Introduction
This chapter describes the features of the NETGEAR Model RT311 and RT314 Internet Access Gateway Routers and discusses planning considerations for installation.

About the Router

The Model RT311 or RT314 Internet Access Gateway Router connects your local area network (LAN) to the Interne t through a n external si ngle-use r access de vice such a s a cable mode m or DSL modem.
When personal computers (PCs) on the LAN need to communicate with locations on the Internet, the PCs send requests to the r out er. The router translates th ose requ ests so that the requests appear to originate from a single PC, rather than from a network of PCs. The router delivers the requests to the external access device for transmission to the Internet.

Key Features

The Model RT311 and RT314 Internet Access Gateway Routers are flexible, high-performance, easy-to-use routers. These routers provide a cost-effective solution for connecting your entire network to a single-user broadband line, such as a cable modem or DSL modem. With minimum setup, you can install and use the router within minutes to meet the networking requirements of your LAN.
Introduction 1-1
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers

Autosensing 10/100 Ethernet

The Model RT311 and RT314 routers connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN interface is autosensing and is capable of full-duplex operation.

TCP/IP

The Model R T 311 and RT314 ro uters sup port t he Transmission Control Protocol/Inte rnet Pr otocol (TCP/IP) and Routing Information Protocol (RIP).
For further information about TCP/IP, refer to Appendix B, “Network and Routing Basics.”
IP Address Masquerading by Dynamic NAT+
The Model RT311 and RT314 routers allow several networked PCs to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Internet service provider (ISP). This technique, an extension of Network Address Translation (NAT), is also known as IP address masquerading and allows the use of an inexpensive single-user ISP account.
Port Forwarding with NAT
Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the router allows incoming traffic to be forwarded to specific PCs based on the service port number of the incoming request.
Automatic Configuration of Attached PCs by DHCP
The Model RT311 and RT314 routers dynamically assign networ k configuration information, including IP, gateway, and domain name server (DNS) addres se s, to attached PCs on the LAN using the Dynamic Host Configuration Protocol (DHCP). This fe ature greatly simplifies configuration of LAN-attached PCs.
DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the router provides its own address as a DNS server to the attached PCs. The router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.
Introduction 1-3
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
PPP over Ethernet (PPPoE)
PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an always-on connection by simulati ng a dial-up connection.

Security

The Model RT311 and RT314 routers are equipped with severa l features designed to maintain security, as described in this section.
PCs Hidden by NAT
Network address translation (NAT) opens a temporary path to the Internet for requests originating from the local network. Requests originating from outside the LAN are discarded, preventing users outside the LAN from finding and directly accessing the PCs on the LAN.
Packet Filtering
The Model RT311 and RT314 routers provide extensive packet filtering capabilities. Packets are allowed or discarded based on their source or destination addresses, service port numbers, or raw data patterns within the packet.
Port-Address Translation
The Model RT311 and RT314 routers perform port-address tra nslation. Requests originating from outside the local network are al lo we d to re ach pa rt icu la r loc al workst ations based on the type of service requested.

Easy Installation and Management

You can install, configure, and operate the Model RT311 or RT314 Internet Access Gateway Router within minutes after connecting it to the network . T he following features simplify installation and management tasks:
Browser-based management
Browser-based configuration allows you to easily configure your router from almost any type of personal computer , such as W indows, Macintosh, or Linux . A user-friendl y Setup Wizard is provided and online help documentation is built into the browser-based Web Management Interface.
Manager Interface
The Manager interface manages and co nfigures th e router thr ough an easily und erstood screen process. You can access this inte rface through the MANAGER port on the rear panel of the router or from across the network, using a Telnet session. The Manager Interface provides access to advanced features such as custom filters.

Connecting the Rout er

Before using your router, you need to do the following:
Connect your local Ethernet network to the LOCAL port(s) of the router (described next).
Connect your cable or DSL modem to the INTERNET port of the router (see page 2-7).
Connect the power adapter (see page 2-8).

Connecting to your Local Ethernet Network

Your local network will attach to the router port or ports marked LOCAL. Because the Model RT314 router includes a four-port switch whil e the Model RT311 router has a single port for connection to your local network, the method of connection is different. Follow the procedure below for your specific mo del .
The LOCAL ports of these rou ters are capable of operation at either 10 Mbps (10BASE-T ) or 100 Mbps (100BASE-Tx), depending on the Ethe rnet interface of the attached PC, hub, or switch. For any connection which will operate at 100 Mbps, you must use a Category 5 (CAT5) rated cable, such as the white Ethernet cable included with the router.
Connecting the Model RT311 router to your Local Area Network
The Model RT311 router has a single por t f or connection to your local network. This port is wir ed as a host rather than a hub, and is intended to connect to a hub or switch in your network. To connect the Model RT311 router to your LAN:
Connect the LOCAL po rt of t he r out er to your existing Ethernet hub or swit ch usi ng the white straight-through Ethernet cable shipped with your router.
To connect the router to a single PC:
Connect the LOCAL port of the router to the Ethernet port of your PC using the red Ethernet crossover cable shipped with your router.
If the Ethernet port of your PC op era te s at 100 Mbp s, you must use a Categ ory 5 rate d cable, such as the red Ethernet cable included with the Model RT311 router.
Connecting the Model RT314 router to your Local Area Network
The Model RT314 router incorporates a four-port switch for connection to your local network. To connect the Model RT314 router to your LAN:
2-6 Setting Up the Hardware
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
Connect up to four PCs directly to any of the four LOCAL ports of the router using standard Ethernet cables.
If your local network cons ists of more than four hosts, you will need to connect your router to another hub or switch:
Connect any LOCAL por t of you r Model R T 314 rout er to th e UPLINK por t of an Ethernet hub or switch using standard Ethernet cable.
If the UPLINK port of your hub or switch is selectable for UPLINK or NORMAL operation, be sure that UPLINK is selected. If the hub or switch does not contain an UPLINK port, you can connect to one of its normal ports using an Ethernet crossover cable.

Connecting to Your Internet Access Device

To connect the ro uter to the Internet (or WAN):
1.
Connect the router’ s INTERNET port to the 10BASE-T Ether net port on your exi sting Internet access device (your ca ble modem or DSL modem).
Note:
The attached modem device must provide a standard 10BASE-T Ethernet connection. The Model RT311 and RT314 routers do not include a cable for this connection. Instead, use the Ethernet cable provided with your access device or any other standard 10BASE-T Ethernet cable. If you are using a DSL modem, the modem’s connection to the phone line remains unchanged.
Note:
The Ethernet cable supplied by your ISP for connecting to your cable or DSL modem may be an Ethernet crossover cable rat her than a st raight- through cable. It is import ant to use th is cable to connect the modem to your router, not to connect your PCs to your router.

Connecting the Serial Cable (Optional)

In normal operation, you will not nee d a ser ial conn ection to the Manager port. This connection is used:
to configure your router using the Manager interface if you cannot use Telnet, or
to restore the router to factory defaults if you have lost your Manager password. To connect the serial cable:
1.
Plug one end of the 9-pin RS-232 cable into the MANAGER port.
Setting Up the Hardware 2-7
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
2.
Plug the other end into a serial port (such as COM1 or COM2) of your PC.
Note:
You must use a 9-pin to 25-pin adapter if your PC has only a 25-pin port
available.

Connecting the Power Adapter

To connect the router to the power adapter:
1.
Plug the connector o f the powe r adapte r into t he 12 VDC adapter o utlet on the rea r panel of the router .
2.
Plug the other end of the adapter into a standard wall outlet.
3.
Verify that the PWR LED on the router is lit.

Verifying Power

After connecting the power adapter to the router and a power source, the router powers on automatica lly. Complete the following steps to verify th at power is correctly applied to the router:
1.
When power is first applied, verify that the PWR LED is on.
2.
Verify that the TEST LED begins to blink within a few seconds.
3.
After approximately 30 seconds, verify that:
a.
The TEST LED is not lit.
b.
The LOCAL LNK/ACT LEDs are lit for any local ports that are connected.
c.
The INTERNET LNK/ACT LED is lit. If a LNK/ACT LED is lit, a link has been established to the connected device.
4.
If a LOCAL port is connected to a 100 Mbps device, verify that the 100 LED is lit.
You are now ready to begin configuration of your network, as described in the following chapter.
2-8 Setting Up the Hardware
Chapter 3
Preparing Your Network
This chapter describes how to prepare your PC network to connect to the Internet through the Model RT311 or RT314 Internet Access Gateway Router and how to order broadband Internet service from an Internet service provider (ISP).

Preparing Your Personal Computers for IP Networking

The Model RT311 and RT314 Internet Access Gateway Routers use the Transmission Control Protocol/Internet Pro toc ol ( TCP/IP). In order to access the Internet through the router, each PC on your network must have TCP/IP installed and selected as the networking protocol.
Note:
In this chapter, we use the term “PC” to refer to personal comp uters in general, and not necessarily Windows computers.
Most operating systems include the software components you need to install and use TCP/IP on your PC:

TCP/IP network.
All versions of UNIX or Linux include TCP/IP components .
Preparing Your Network 3-1
95 or later (including Windows NT®) includes the software components for
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
Follow the instructions provided with your operating system or networking software to install TCP/IP on your computer. Although TCP/IP is built into the Windows operating system (starting with Windows 95), you need to enable and configure it as described in “Configuring Windows 95
or later for IP Networking” on page 3-2. To configure the Macintosh, see “Configuring the Macintosh for IP Networking on page 3-5.
In your IP network, all PCs and the r out er mus t be assign ed IP addresses. Each PC must also have certain other IP co nfigur atio n infor mation such as a subnet mask (ne tmask), a do main name server (DNS) address, and a default gate way address. In most cases, you should ins tall TCP/IP so that the PC obtains its specifi c network config urati on inform ation from a DHCP serve r duri ng bootup . For a detailed explanation of the meaning and purpose of these configuration items, refer to “Appendix B, “Networks, Routing, and Firewall Basics.”
The Model RT311 and RT314 routers are shipped preconfigured as a DHCP server. The router assigns the following TCP/IP configuration information automatically when the PCs are rebooted:
PC or workstation IP addresses—192.168.0.2 through 192.168.0.31
Subnet mask—255.255.255.0
Gateway address (the router)—192.168.0.1 These addresses are part of the IETF-designated private address range for use in private networks.

Configuring Windows 95 or later for IP Networking

As part of the PC preparatio n process, you need to manually install and configure TCP/IP on ea ch networked PC. Before starting, locate your Windows CD; you may need to insert it during the TCP/IP installation process.
To configure Microsoft
1.
On the Wi ndo ws t as kbar, click the Start button, poi nt t o Se tt ing s, and then click Control Panel.

3.
Restart your PC for the changes to take effect.

Configuring TCP/IP Properties

After the TCP/IP protocol components are installed, each PC must be assigned specific information about itself and resources that are available on its network. The simplest way to configure this information is to allow the PC to obtain the information from the internal DHCP server of the Model RT311 and RT314 routers.
Note:
If an ISP technician configured your PC during the installation of a broadband modem, or if you configur ed it us ing inst ructions provided by your IS P, you may need t o copy the current configuration information for use in the configuration of your router. Refer to “Obtaining ISP Configuration Information (Windows)” on page 3-8 or
“Obtaining ISP Configuration Information (Macintosh)” on page 3-9 for further
information.
If you are using DHCP with the recommended default addresses, you can configure your PCs by following these steps:
1.
Install TCP/IP on each PC, leaving the PC configured to obtain configuration settings automatically (by DHCP).
2.
Physically connect the PCs and the router using a hub or a direct connection.
3.
Restart the ro uter and allow it to boot.
4.
Restart each PC.

Verifying TCP/IP Properties (Windows)

After your PC is configured and has rebooted, you can check the TCP/IP configuration using the Windows 95 and 98 utility
3-4 Preparing Your Network
winipcfg.exe
(for Windows NT systems, use
ipconfig.exe
).
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
To check your PC’s TCP/IP configuration:
1.
On the Windows taskbar, click the Start button, and then click Run. The Run window opens. Type
winipcfg
, and then click OK.
2.
The IP Configuratio n window opens, which list s (among other things), your IP addr ess, subnet mask, and default gateway.

The subnet mask is 255.255.255.0
The default gateway is 192.168.0.1

Configuring the Macintosh for IP Networking

Beginning with Macintosh Operating System 7, TCP/IP is already installed on the Macintosh. On each networked Macintosh, you will need to configure TCP/IP to use DHCP by following these steps:
1.
From the Apple menu, select Control Panels, then TCP/IP. The TCP/IP Control Panel opens:
Preparing Your Network 3-5
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
2.
From the “Connect via” box, select your Macintosh’s Ethernet interface.
3.
From the “Configure” box, select Using DHCP Server. You can leave the DHCP Client ID box empty.
4.
Close the TCP/IP Control Panel.
5.
Repeat this for each Macintosh on your network.

Verifying TCP/IP Proper ties (Macintosh)

After your Macintosh is configured and has rebooted, you can check the TCP/IP configuration by returning t o the TCP/IP Control Panel. From the Ap ple menu, select Control Panels, then TCP/IP.
The panel is updated to show your settings, which should match the values below if you are using the default TCP/IP settings that NETGEAR recommends:

The Subnet mask is 255.255.255.0
The Router address is 192.168.0.1
If you do not see these values, you may need to restart your Macintosh or you may need to switch the “Configure” setting to a different option, then back again to “Using DHCP Server”.
3-6 Preparing Your Network
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers

Your Internet Account

For access to the Internet, you need to contract with an Internet service provider (ISP) for a single-user Internet access account using an external broadband access device such as a cable modem or DSL modem. This modem must be a separate physical box (not a card) and must provide an Ethernet port intended for connection to a Network Interface Card (NIC) in a PC.
For a single-user Internet account, your ISP supplies TCP/IP configuration information for one PC. With a typical account, much of the configuration information is dynamically assigned when your PC is first bo ote d up whi l e co nnec te d to the ISP, and you will not need to know that dynamic information.
In order to share the Internet connection among several computers, your router takes the place of the single PC, and you need to configure it with the TCP/IP information that the single PC would normally use. When the route r’ s INTERNET port is connected to t he broadband modem, the r outer appears to be a single PC to the ISP. The router then allows the PCs on the local network to masquerade as the single PC to access the Internet through the broadband modem. The method used by the router to accomplish this is called Network Address Translation (NAT) or IP masquerading.

Login Protocols

Some ISPs require a special login protocol. In this case, you will need to know what type of protocol is used, and you will need a login name and password. The two common protocols are:
PPP over Ethernet (PPPoE) Two common PPPoE clients are WinPOET and EntreNet.
RoadRunner Not all RoadRunner service areas require a login protocol. If your ISP is RoadRunner, you should ask whether your PC must run a RoadRunner login program.
After your network and router are configured, the router will perform the login task when needed, and you will no longer need to login from your PC.

Account Information

Unless these items are dynamically assigned by the ISP, your ISP should give you the following basic information for your account:
Preparing Your Network 3-7
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
An IP address and subnet mask
A gateway IP address, which is the address of the ISP’s router
One or more domain name server (DNS) IP addresses
Host name and domain suffix For example, your account’s full server names may look like this:
mail.xxx.yyy.com
In this example, the domain suffix is
xxx.yyy.com
.
If any of these items are dyna mically suppli ed by the IS P, your router automat ically acquir es them. If an ISP technici an configured your PC during the instal lat i on of the broadband modem, or if you configured it using ins tr uct io ns provided by your ISP, you need to copy configuration information from your PC’s Network TCP/IP Properties window (or Macintosh TCP/IP Control Panel) before reconfiguring your PC for use with the router. These procedures are described next.
Obtaining ISP Configuration Information (Windows)
As mentioned above, you may nee d t o collect configuration information from your PC s o t hat you can use this information when you conf igu re the Model RT311 and R T31 4 rout er s. Fol lowi ng this procedure is only necessary when your ISP does not dynamically supply the account information.
To get the information you need to configure the router for Internet access:
1.
On the Wi ndo ws t as kbar, click the Start button, poi nt t o Se tt ing s, and then click Control Panel.
2.
Double-click the Network icon. The Network window opens, which displays a list of installed components.

Dynamic DNS

Your router supports Dynamic Domain Name Service (DDNS). In a Dynamic DNS service, an IP registry server provi des a public cent ral dat abase where dynamicall y-ass igned IP ad dre sses can be stored and retrieved by hostname lookup. The Dynamic DNS server also stores password-protected e-mail addresses along with IP addresses and hostnames and accepts queries based on e-mail addresses.
To utilize this service, you must register with the Dynamic DNS service provider, who will give you a password or key. At this time, the Model RT311 and RT314 routers only support DynDNS service. For more information, visit www.dyndns.org.
The configuration fields for Dynamic DNS are shown in Table 5-1:
Table 5-1. Dynamic DNS configuration fields
Field Description
Active Use this field to activate or deactivate dynamic DNS registration. Service Provider Select a dynamic DNS servic e provider. Host Name Enter the static host name that will link to your dynamic IP address. E-Mail Address Enter your email address for administrative contact. User Enter the user name of your dynamic DNS account. Password Enter the password of your dynamic DNS account. Enable Wildcard DynDNS.org allows the use of wildcards in resolving your URL.

The second feature category under the Advanced heading is LAN Setup. This menu allows configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser interface, under Advanced, click on LAN to view the LAN Setup menu, shown in Figure 5-1
Figure 5-1. LAN Setup Menu

DHCP

The Model RT311 and RT314 routers have the capability to act as a DHCP server, allowing them to assign IP, DNS, and default gateway addresses to attached PCs. The assigned default gateway address is the LAN address of the router. IP addresses will be assigned to the attached PCs from a pool of addresses specified in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
See “IP Configuration by DHCP” on page B-10 for an explanation of DHCP and information about how to assign IP addresses for your network.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. These default settings are:
DHCP server enabled with 32 client addresses starting from 192.168.0.1.

Table 5-2. DHCP Setup Fields
Field Description
DHCP Server: If this box is checked, the router acts as a DHCP server.
If this box is cleared, the router’s DHCP server is disabled. Pool Starting Address The beginning of the range of IP addresses to assign. Count The number of sequential addresses available for assignment to
attached hosts. The maximum is 32. Primary DNS Server If you want the router to provide the Primary DNS Server address to
attached hosts, enter t he DNS ad dress in th is fie ld. If thi s field is 0.0. 0.0,
the router assigns its own address as DNS Server , a nd perfo rm s a D NS
Proxy if it can obtain a DNS address from the ISP. Secondary DNS Server If you want the router to assign the Secondary DNS Server address
to attached hosts, enter the address in this field.

LAN TCP/IP

Table 5-3 lists and describes the fields to use for setting up TCP/IP parameters for the LAN...
Table 5-3. LAN TCP/IP Setup Fields
Field Description
TCP/IP Setup:
IP Address Enter the IP address of the LAN interface of the router in dotted-decimal
notation (four 8-bit numbers, between 0 and 255, separated by periods,
for example, 192.168.0.1). Every device on the TCP/IP network must
have a unique IP address. IP Subnet Mask An IP address consists of two parts, the network ID and the host ID. The
IP Subnet Mask specifies the network ID portion of the address, written
in dotted-decimal notatio n. The rou ter autom atically calculates this m ask
for the class of the IP address that you assign. Unless you have a
special need for subnetting, use the default subnet mask calculated by
the router. All hosts on the LAN segment should use the same mask.
5-4 Advanced Configuration of the Router
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
Table 5-3. LAN TCP/IP Setup Fields (continued)
Field Description
RIP Direction This parameter determines how the router handles RIP (Routing
Information Protocol). RIP allows the router to exchange routing
information with other routers. If set to None (default), the router does
not participate in any RIP exchange with other routers. If set to Both, the
router broadcasts the routing table of the router on the LAN and
incorporates RIP broadcasts by other routers into its routing table. If set
to In Only, the router broadcasts its routing table on the LAN. If set to
Out Only, the router broadcasts its routing table, but it ignores any RIP
broadcast packets that it receives. Usually, you should leave this
parameter at the default (None)
RIP Version This field determines the format and broadcasting method of any RIP
(Routing Information Protoc ol) transmiss ions by the router . The following
RIP options are supported by the Model RT311 router:
• RIP-1—The router sends RIP-1 messages only.
• RIP-2B—The router sends RIP-2 messages in broadcast format.
• RIP-2M—The router send s RIP-2 messag es in multicast format.
For most applications, the recommended version is RIP-1.
Multicast Some streaming media applications (e.g. Cisco IP/TV, RealPlayer) now
support IP Multicast. To enable Multicast routing, select either IGMP-v1
or IGMP-v2.
.
Note:
If you change the LAN IP address of the router while connected through the browser or Telnet, you will be disconnected. You must then open a new connection to the new IP address and log in again.

Configuring for Port Forwarding to Local Servers

Although the router cause s your entire local network to appear as a single machine to th e I nte rne t, you can make local servers for dif ferent ser vices (f or example, FTP or HTTP) visible an d availabl e to the Interne t. This is done using the PORTS menu. From th e Main Menu of the browser interface, under Advanced, click on PORTS to view the port forwarding screen, shown in
Figure 5-2
Figure 5-2. Port Forwarding Menu
Requested services ar e identi fied by port nu mbers in an incoming I P packet. For example, a pa cket that is sent to the external IP address of your router and destined for port number 80 is an HTTP (Web server) request, and port 21 is an FTP request. Examples of port numbers are shown at the top of the PORTS menu, although you are not limited to these choices. See IETF RFC1700, “Assigned Numbers,” for port numbers for common protocols..
Note:
Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.
5-6 Advanced Configuration of the Router
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
Use the PORTS menu to configure the router to forward incoming protocols to IP addresses on your local network based on the port number . In addition to servers for specific protoc ols , yo u ca n also specify a Default (also called DMZ) Server to which all other incoming protocols are forwarded. To configure port forwarding to a local server:
1.
Enter the Port Number in an unused Port # box.
2.
Enter the IP address of the local server in the corresponding Server IP Address box.
3.
Click Apply at the bottom of the menu.

Local Web and FTP Server Example

If a local PC, with a private address of 192.168.0.33, acts as a Web and FTP server, configure the POR TS menu to forward ports 80 (HTTP) and 21 (FTP) to l oca l address 192.168.0.33 as shown in
Table 5-4.
Table 5-4. Port Table Entries (Example)
Port # Server IP Address
Default 0.0.0.0 80 (HTTP) 192.168.0.33 21 (FTP) 192.168.0.33
In order for a remote user to access this server from the Internet, the remote user must know the IP address that has been as si gned by your ISP. If this address is 172.16.1.23, for examp le, an In ternet user can access your Web server by directing the browser to http://172.16.1.23. The assigned IP address can be found in the Maintenance Status Menu, where it is shown as the WAN IP Address.
Some consid erations for this application are:
If your account’s IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires.
If the IP address of t he loca l PC is ass igned by DHCP, it may ch ange when t he PC is reb ooted. To avoid this, change the configuration of your PCs to use fixed private addresses rather than DHCP-assigned addresses.
Local PCs must access t he local ser ver using th e PCs’ local LAN addr ess (192.168 .0.33 in this example). Attempts by local PCs to access the server using the external IP address (172.16.1.23 in this example) will fail.

Local Game Host or Videoconference Example

Some online games and videoc onferencing applications are incompatible with NAT. The Model Model RT311 and RT314 routers are programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local PC can run the application properly if that PC’s IP address is entered as the default in the PORTS Menu. If one local PC acts as a game or videoconference host, enter its IP address as the default.

Static Routes

The fourth feature category under the Advanced heading is Static Route, which allows configuration of additional routing information. Under normal ci rcumstances, the router has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network.
From the Main Menu of the browser interface, under Advanced, click on Static Route to view the Static Route menu, shown in Figure 5-3.

Figure 5-4. Static Route Entry and Edit Menu
Table 5-5 lists and describes the fields for the IP Static Route Edit menu.
Table 5-5. Edit IP Static Route Fields
Field Description
Route Name Enter a descriptive name for this route for identification purposes only. Active Use this field to activate or deactivate this static route. Destination IP Address Enter the IP network address of the final destination. Routing is always based
on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the
network number to be identical to the host ID. IP Subnet Mask Enter the subnet mask for this destination. Gateway IP Address Enter the IP address of the gateway to the destination network. The gateway
is the next router that your router contacts in order to forward packets to the
destination. On the LAN, the gate way must be a ro uter on the same segment
as the router. Over the WAN, the gateway will be the IP address of the rou ter
at your ISP.
Advanced Configuration of the Router 5-9
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
Table 5-5. Edit IP Static Route Fields (continued)
Field Description
Metric Enter the cost in ‘hops’ of transmission for routing purposes. IP routing uses
hop counts as the measurement of cost, with a minimum of 1 for directly
connected networks. Enter a number that approximates the cost for this link.
The number does no t have to be precise , but i t must b e betw een 1 and 16. In
practice, 2 or 3 is usually a good number. Private Use this field to determine whether the router includes the route to this
remote node in it s R I P bro adc as ts. If set to Yes, thi s rout e is kept private and
not included in any RIP broadcast. If set to No, the route to this remote node
is propagated to other hosts through RIP broadcasts.

Static Route Example

As an example of when a static route is needed, consider the following case:
Your primary Internet access is through a cable modem to an ISP.
You have an ISDN router on your home network for connecting to the company where you are employed. This rout er’s address on your LAN is 192.168.0.100.
Your company’s network is 134.177.0.0.
When you first configur ed your r outer, t wo implic it st atic routes were cr eated . A defaul t rout e was created with your ISP as the gateway, and a second static route was created to your local network for all 192.168.x.x addresses. With this configuration, if you attempt to access a device on the
134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your request to the company where you are employed, and the request will likely be denied by the company’s firewall.
5-10 Advanced Configuration of the Router
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.100. The static route would look like Figure 5-5.
Figure 5-5. Static Route Example
In this exampl e:
The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.x.x addresses.
The Gateway IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100.
A Metric value of either 1 or 2 will work.
Private is selected only as a precautionary security measure in case RIP is activated.

Using the Manager Interface for Initial Router
Configuration
This chapter contains information about basic configuration for your Model RT311 or RT314 Internet Access Gateway Router using the internal Manager interface. The initial configuration consists of :
accessing the Manager, – naming the router, – and setting up the LAN interface, including DHCP parameters to be assigned to the
attached PCs.
After you have performed basic router configuration, proceed to Chapter 8, “Using the Manager
Interface to Configure the Router for Internet Access,” and Chapter 10, “Configuring Filters,” to
configure Internet access and additional features.
Note:
You can also use the browser-based setup to configure basic router features, and
later use the Manager interface to configure advanced fe atures.

Connecting for Configuration

The Manager interface is accessible by a serial connection through the MANAGER port on the rear panel of your router or by a Telnet connection over the local network, as described in the following sections.
Using the Manager Interface for Initial Router Configuration 7-1
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers

Connecting Through a Serial Port

You can access the internal Manager interface through a serial port by using a VT100 terminal or by using a terminal-emulation program on your PC or workstation. If you are using Windows, for example, Microsoft
®
provides HyperTerminal with Windows 95 and Windows 98. Be sure to set
the program for VT100 emulation, including arrow keys. Serial port parameters are as follows:
9600 bps
8 data bits
•1 stop bit
No parity
No flow control When the serial connection has been established, press any key. The router should respond with a
“Password:” prompt. Type the current password to access the Manager interface. The default password is 1234.

Connecting Through a Telnet Connection

You can access the built-in interface by a Telnet call from any TCP/IP workstation on the LAN or the remote network. In order to use the Telnet Protocol, you must know the current IP address of the router. If you do not know the router’s current IP address, you must use a serial connection to assign an IP address. The router is shippped with a default address of 192.168.0.1.
To establish a Telnet connection from the LAN, you must set up your workstation to reach the IP address of the router by doing one of the following:
Set your workstation to an IP address on the currently programmed subnet of the router.
Add a route to the static routing table of the workstation to indicate that the router can be reached through the local LAN port.
To access the router by Telnet from a Windows PC:
From the Windows toolbar, select Start.
1.
Select Run...
2.
In the Open field, type:
3.
telnet 192.168.0.1
7-2 Using the Manager Interface for Initial Router Configura tio n
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
Click on OK.
4.
The router should respond with a “ Passwor d:” prompt. Type the current pass word to access t he Manager interface. The default password is 1234.
.When using Telnet, consider the following restrictions:
Single administrator To prevent confusion and discrepancy on the configuration, the router allows only one
terminal connection at any time. The router also gives priori ty to the RS-232 connection over Telnet. If you have already connected to the router through Telnet, you are logged out if another user then connects through the RS-232 cable. You can use a Telnet connection only after the other administrator has disconnected.
System timeout When you are connected to the router through Telnet, there is a system timeout of 5 minutes
(300 seconds). If you are not configuring the device and leave it inactive for this timeout period, the router automatically disconnects from the Telnet session.

TCP/IP and DHCP Setup
The Model RT311 and RT314 routers have the capability to act as a DHCP server, allowing them to assign IP, DNS, and default gateway addresses to attached PCs or workstations. The assigned default gateway address is the LAN address of the router, as set in the TCP/IP section. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
If you are setting up your network for the first time, read about IP addresses starting with “IP
Addresses and the Internet” on page B-2 and “IP Configuration by DHCP” on page B-10 for an
explanation of DHCP and information about how to assign IP addresses for your network. For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. These
default settings are:
LAN IP address 192.168.0.1 with subnet mask 255.255.255.0.
DHCP server enabled with 32 client addresses starting from 192.168.0.1.
DNS Proxy enabled (the router address is assigned as a DNS server).

Field Description
RIP Direction This parameter determines how the router handles RIP (Routing
Information Protocol). RIP allows the router to exchange routing information with other routers. If set to None (default), the router does not participate in any RIP exchange with other routers. If set to Both, the router broadcasts the routing table of the router on the LAN and incorporates RIP broadcasts by other routers into its routing table. If set to In Only, the router broadcasts its routing table on the LAN. If set to Out Only, the router broadcasts its routing table, but it ignores any RIP broadcast packets that it receives. Usually, you should leave this parameter at the default (None)
RIP Version This field determines the format and broadcasting method of any RIP
(Routing Information Protoc ol) transmiss ions by the router . The following RIP options are supported by the Model RT311 router:
• RIP-1—The router sends RIP-1 messages only.
• RIP-2B—The router sends RIP-2 messages in broadcast format.
• RIP-2M—The router send s RIP-2 messag es in multicast format. For most applications, the recommended version is RIP-1.
Multicast Some streaming media applications (e.g. Cisco IP/TV, RealPlayer) now
support IP Multicast. To enable Multicast routing, select either IGMP-v1 or IGMP-v2.

You can press [Esc] at any time to cancel your selections. When you save this menu, the router automatically creates a default static route to the ISP.

Configuration for Local Servers

Although NAT causes your entire local network to appear as a single machine to the Internet, you can make local servers for different services (for example, FTP or HTTP) visible and available to the Internet. Requested services are identified by port numbers in an incoming IP packet. For example, a packet that is sent to the exte rnal IP address of your rout er and destined for port nu mber 80 is an HTTP (Web server) request, and port 21 is an FTP request. Examples of port numbers are shown at the bottom of Menu 15, although you are not limited to these choices. See IETF RFC1700, “Assigned Numbers,” for port numbers for common protocols..
Note:
Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.
Using the Manager Interface to Configure the Router for Internet Access 8-3
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
Use Menu 15, SUA Server Setup, to configure the router to forward incoming protocols to IP addresses on your local network based on the port number. In addition to servers for specific protocols, you can also specify a default server to which all other incoming protocols are forwarded.

8-4 Using the Manager Interface to Configure the Router for Internet Access
Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers
In order for a remote user to access this server from the Internet, the remote user must know the IP address that has been as si gned by your ISP. If this address is 172.16.1.23, for examp le, an In ternet user can access your Web server by directing the browser to http://172.16.1.23. The assigned IP address can be found in Menu 24.1, in the WAN IP Address field.
Some consid erations for this application are:
If your account’s IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires.
If the IP address of t he loca l PC is ass igned by DHCP, it may ch ange when t he PC is reb ooted. To avoid this, change the configuration of your PCs to use fixed private addresses rather than DHCP-assigned addresses.
Local PCs must access the local server using the PCs’ local LAN address (192.168.0.3 in this example). Attempts by local PCs to access the server using the external IP address (172.16.1.23 in this example) will fail.

Local Game Host or Videoconference Example

Some online games and videoc onferencing applications are incompatible with NAT. The Model Model RT311 and RT314 routers are programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local PC can run the appli cation prop erly if that PC’s IP address is entered as the default in Menu 15. If one local PC acts as a game or videoconference host, enter its IP address as the default.

Setting Static Routes

Under normal circumstances, the router has adequate routing information after you configure the Internet access information, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network.
To view the routes in the routing table:
In the Manager interface, open Menu 24 - System Maintenance.

Static Route Example

As an example of when a static route is needed, consider the following case:
Your primary Internet access is through a cable modem to an ISP.
You have an ISDN router on your home network for connecting to the company where you are employed. This rout er’s address on your LAN is 192.168.0.10.
Your company’s network is 134.177.0.0.
When you first config ure d your Model Mo del RT311 and RT314 routers, two implici t st atic routes were created. A default route was created with your ISP as the gateway, and a second static route was created to your local network for all 192.168.x.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 ne twork, your router will forwar d your reques t to the ISP. The ISP forwards your request to the company where you are employed, and the request will likely be denied by the co mpany’s firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN r outer at 192.1 68.0.10. The stat ic rou te woul d look l ike Figure 8-5.

Back Up and Restore Configuratio n

You can save the router configuration settings to a disk as a binary file. You can also restore the settings from the file at a later time. Saving and restoring the router configuration lets you restore the router to working order if the configuration information in the router is lost or damaged. You can also use the configuration file to configure a new router of the same type if it becomes necessary to replace the router.
NETGEAR highly recommends backing up your router configuration after the router is functioning. You can perform the backup and restore operations through a serial connection using a terminal emulatio n program ( such as Hyp erTerm), or over the LAN using the Telnet protocol and a third-party FTP program. The procedures are described in the following sections.

Backing Up and Restoring the Configuration with a Serial Connection

Your serial communications software must have the ability to transfer data using the XMODEM Protocol.
To back up the configuration with a serial connection:
Establish a serial connection with the router.
1.
For more information, see “Connecting Through a Serial Port“ on page 7-2.
Select Menu 24 - System Maintenance.
2.
Enter 5 to select Backup Configuration.
3.
You are prompted to receive the file using the XMODEM transfer function of your terminal emulation program.
To restore the configuration:
Establish a serial connection with the router.
1.
For more information, see “Connecting Through a Serial Port“ on page 7-2.
Select Menu 24 - System Maintenance.
2.
Enter 6 to select Restore Configuration.
3.
You are prompted to send the file using the XMODEM transfer function of your terminal-emu lation program.

The procedure for receiving or sending the configuration file varies depending on the type of terminal software used to access the router.

Backing Up and Restoring the Configuration Using F TP

To back up or restore the configuration file over the LAN, you must have an FTP client program. Windows includes an FTP client program that can be accessed using the Start button and Run menu. Other FTP client programs are avai lable through many software retailers and shareware sites.
To back up or restore the configuration:
If you are sending a configuration file to the router, first rename it to rom-0.
1.
Establish an FTP connection to the LAN IP address of the router.
2.
No login name is necessary. The password is the current Manager password. The factory default password is 1234.
Select binary (not ascii) transfer mode.
3.
Use your FTP program to get (back up) or put (restore) the file named rom-0 in the
4.
router.

Software Update

You can update the router software updates either by using the serial cable connection or by using an FTP program.

Updating Router Software Using FTP

You can update the router so ft ware over the LAN using an FTP client program. Windows i ncl ude s an FTP client program that can be accessed using the Start button and Run menu. Other FTP client programs are available through many software retailers and shareware sites.
To update the router software:
Rename the new software file to ras.
1.
Establish an FTP connection to the LAN IP address of the router.
2.
No login name is necessary. The password is the current Manager password. The factory default password is 1234.
Select binary (not ascii) transfer mode.
3.
Use your FTP program to put the file named ras in the router.
4.
After the data tr ansfer is finished, the router pr ograms the upgraded firmware into flash memory and reboots itself, dropping the FTP session.
