Wireless-G ADSL Home Gateway

Chapter 1: Introduction

Welcome

Thank you for choosing the Wireless-G ADSL Home Gateway. This Gateway will provide your computers with a high-speed Internet connection as well as resources, including files and printers. Since the Gateway is wireless, Internet access can be shared over the wired network as well as the wireless broadcast at up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G.

How does the Gateway do all of this? By connecting the Internet, as well as your computers and peripherals, to the Gateway, then the Gateway can direct and control communications for your network.

To protect your data and privacy, the Gateway features an advanced firewall to keep out Internet intruders. Wireless transmissions can be protected by powerful data encryption. In addition, you can safeguard your family with parental control features such as Internet access restrictions and keyword blocking. You can configure the Gateway’s settings through the easy-to-use, browser-based utility.

But what does all of this mean?

Networks are useful tools for sharing Internet access and computer resources. You can access one printer from different computers and access data located on another computer’s hard drive. Networks are even used for playing multiplayer video games. So, networks not only are useful in homes and offices, but also can be fun.

PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is why the network is called “wired”. PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called a WLAN, or Wireless Local Area Network. Since the Gateway has wireless capabilities, it can bridge your wired and wireless networks, letting them communicate with each other.

With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet access—and even play games. All the while, the Wireless-G ADSL Home Gateway protects your networks from unauthorized and unwelcome users.

Linksys recommends using the Setup CD-ROM for first-time installation of the Gateway. If you do not wish to run the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the Gateway, set it up, and configure it to bridge your different networks. These instructions should be all you need to get the most out of the Wireless-G ADSL Home Gateway.

wpa (wi-fi protected access): a wireless security protocol using TKIP (Temporal Key Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server.

spi (stateful packet inspection) firewall: a technology that inspects incoming packets of information before allowing them to enter the network.

firewall: Security measures that protect the resources of a local network from intruders.

nat (network address translation): NAT technology translates IP addresses of a local area network to a different IP address for the Internet.

network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users

lan (local area network): The computers and networking products that make up the network in your home or office.

Wireless-G ADSL Home Gateway

Chapter 2 : Planning Y our Network

The Gateway’s Functions

A Gateway is a network device that connects two networks together.

In this instance, the Gateway connects your Local Area Network (LAN), or the group of computers in your home or office, to the Internet. The Gateway processes and regulates the data that travels between these two networks.

The Gateway’s NAT feature protects your network of computers so users on the public, Internet side cannot “see” your computers. This is how your network remains private. The Gateway protects your network by inspecting every packet coming in through the Internet port before delivery to the appropriate computer on your network. The Gateway inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate computer on the LAN side.

Remember that the Gateway’s ports connect to two sides. The LAN ports connect to the LAN, and the ADSL port connects to the Internet. The LAN ports transmit data at 10/100Mbps.

IP Addresses

What’s an IP Address?

IP stands for Internet Protocol. Every device on an IP-based network, including computers, print servers, and Gateways, requires an IP address to identify its “location,” or address, on the network. This applies to both the Internet and LAN connections. There are two ways of assigning an IP address to your network devices. You can assign static IP addresses or use the Gateway to assign IP addresses dynamically.

Static IP Addresses

A static IP address is a fixed IP address that you assign manually to a computer or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses must be unique and are commonly used with network devices such as server computers or print servers.

Chapter 2: Planning Your Network The Gateway’s Functions

Figure 2-1: Network

ip (internet protocol): a protocol used to send data over a network

NOTE: Since the Gateway is a device that connects two networks, it needs two IP addresses—one for the LAN, and one for the Internet. In this User Guide, you’ll see references to the “Internet IP address” and the “LAN IP address.”

Since the Gateway uses NAT technology, the only IP address that can be seen from the Internet for your network is the Gateway’s Internet IP address. However, even this Internet IP address can be blocked, so that the Gateway and network seem invisible to the Internet—see the Block WAN Requests description under Security in “Chapter 5: Configuring the Wireless-G ADSL Home Gateway.”

Wireless-G ADSL Home Gateway

Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Gateway. You can get that information from your ISP.

Dynamic IP Addresses

A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers. These IP addresses are called “dynamic” because they are only temporarily assigned to the computer or device. After a certain time period, they expire and may change. If a computer logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will automatically assign it a new dynamic IP address.

DHCP (Dynamic Host Configuration Protocol) Servers

Computers and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP server. The computer or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.

A DHCP server can either be a designated computer on the network or another network device, such as the Gateway. By default, the Gateway’s DHCP Server function is enabled.

If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Gateway, see the DHCP section in “Chapter 5: Configuring the Wireless-G ADSL Home Gateway.”

Wired Connection to a Computer

1. Make sure that all of your network’s hardware is powered off, including the Gateway and all computers.

2. Connect a phone cable from the Line port on the Gateway’s side panel to the wall jack of the ADSL line. A small device called a microfilter (not included) may be necessary between each phone and wall jack to prevent interference. Contact your ISP if you have any questions.

NOTE:

A small device called a microfilter (not included) may be necessary between each phone

and wall jack to prevent interference. Contact your ISP if you have any questions.

IMPORTANT: For countries that have phone jacks with RJ-11 connectors, make sure to only place the microfilters between the phone and the wall jack and not between the Gateway and the wall jack or your ADSL will not connect.

For countries that do not have phone jacks with RJ-11 connectors (e.g. France, Sweden, Switzerland, United Kingdom, etc.), except for ISDN users, the microfilter has to be used between the Gateway and the wall jack, because the microfilter will have the RJ-11 connector.

Annex B users (E1 and DE versions of the Gateway) must use the included special cable to connect the Gateway to the wall jack (RJ-45 to RJ-12). If you require splitters or special jacks, please contact your service provider.

3. Connect one end of an Ethernet network cable to one of the Ethernet ports (labeled 1-4) on the back of the Gateway, and the other end to an Ethernet port on a computer.

Repeat this step to connect more computers, a switch, or other network devices to the Gateway.

4. Connect the power adapter to the Gateway’s Power port, and then plug the power adapter into a power outlet.

NOTE: You should always plug the Gateway’s power adapter into a power strip with surge protection.

• Network Address Server Settings (DHCP). Configure the Gateway’s Dynamic Host Configuration Protocol (DHCP) settings in this section.

• Local DHCP Server. A Dynamic Host Configuration Protocol (DHCP) server automatically assigns an IP

address to each computer on your network for you. Unless you already have one, it is highly recommended that you leave the Gateway enabled as a DHCP server. You can also use the Gateway in DHCP Relay mode.

• DHCP Relay Server. If you enable the DHCP Relay mode for the Local DHCP Server setting, enter the IP

address for the DHCP server in the fields provided.

• Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. This value

must be 192.168.1. 2 or greater, because the default IP address for the Gateway is 192.168.1.1.

• Maximum Number of DHCP Users. Enter the maximum number of users/clients that can obtain an IP

address. The number will vary depending on the starting IP address entered.

• Client Lease Time. The Client Lease Time is the amount of time a computer will be allowed connection to

the Gateway with its current dynamic IP address. Enter the amount of time, in minutes, that the computer will be “leased” this dynamic IP address.

The Advanced Routing Tab

The Advanced Routing screen allows you to configure the NAT, dynamic routing, and static routing settings.

Advanced Routing

• Operating Mode. In this section, you will configure the Gateway’s general routing settings.

• NAT. NAT is a security feature that is enabled by default. It enables the Gateway to translate IP addresses

of your local area network to a different IP address for the Internet. To disable NAT, click the Disabled radio button.

• RIP. If you have multiple routers, you may want to use the Routing Information Protocol (RIP) so the routers

can exchange routing information with each other. To use RIP, select the Enabled radio button. Otherwise, keep the default, Disabled.

• Send Default Route. To use RIP version 1 for routing, select the Enabled radio button. Otherwise, keep the

default, Disabled.

• Interface. This setting is available when you have configured a static route and you need to choose an

interface for that route. Select the interface that the Gateway will be using: LAN/Wireless or Internet.

• Dynamic Routing. With Dynamic Routing you can enable the Gateway to automatically adjust to physical changes in the network’s layout. Using RIP, the Gateway determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other Gateways on the network.

• Transmit RIP Version. To transmit RIP messages, select the protocol you want: RIP1, RIP1-Compatible,

or RIP2. If you don’t want to transmit RIP messages, select None.

• Receive RIP Version. To receive RIP messages, select the protocol you want: RIP1 or RIP2. If you don’t

want to receive RIP messages, select None.

• Multicast or Broadcast. RIP can be sent using either methods. If you want to use multicasting, select

Multicast. If you want to use Broadcast, select Broadcast.

• Static Routing. If the Gateway is connected to more than one network, it may be necessary to set up a static route between them. A static route is a pre-determined pathway that network information must travel to reach a specific host or network. To create a static route, change the following settings:

Chapter 5: Configuring the Wireless-G ADSL Home Gateway The Setup Tab

Wireless-G ADSL Home Gateway

• Select set number. Select the number of the static route from the drop-down menu. The Gateway

supports up to 20 static route entries. If you need to delete a route, then select the entry and click the Delete This Entry button.

• Destination IP Address. The Destination IP Address is the address of the remote network or host to which

you want to assign a static route. Enter the IP address of the host for which you wish to create a static route. If you are building a route to an entire network, be sure that the network portion of the IP address is set to 0.

• Subnet Mask. Enter the Subnet Mask (also known as the Network Mask), which determines which portion

of an IP address is the network portion, and which portion is the host portion.

• Gateway. Enter the IP address of the gateway device that allows for contact between the Gateway and the

remote network or host.

• Hop Count. Hop Count is the number of hops to each node until the destination is reached (16 hops

maximum). Enter the Hop Count in the field provided.

• Show Routing Table. Click the Show Routing Table button to open a screen displaying how data is routed through your local network. For each route, the Destination LAN IP address, Subnet Mask, Gateway, and Interface are displayed. Click the Refresh button to update the information. Click the Close button to return to the previous screen.

The Wireless Tab

The Basic Wireless Settings Tab

This screen allows you to choose your wireless network mode and wireless security.

Wireless Network

• Wireless Network Mode. If you have 802.11g and 802.11b devices in your network, then keep the default

setting, Mixed. If you have only 802.11g devices, select 802.11g. If you have only 802.11b devices, select

802.11b. If you want to disable wireless networking, select Disabled.

• Wireless Network Name (SSID). Enter the name for your wireless network into the field. The SSID is the network name shared among all devices in a wireless network. It must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any keyboard character. Linksys recommends that you change the default SSID (linksys) to a unique name of your choice.

• Wireless Channel. Select the appropriate channel from the list provided to correspond with your network settings. All devices in your wireless network must use the same channel in order to function correctly. Wireless computers or clients will automatically detect the wireless channel of the Gateway.

• Wireless SSID Broadcast. When wireless computers or clients survey the local area for wireless networks to associate with, they will detect the SSID broadcast by the Gateway. To broadcast the Gateway's SSID, keep the default setting, Enable. If you do not want to broadcast the Gateway's SSID, then select Disable.

The Wireless Security Tab

The Wireless Security settings configure the security of your wireless network. There are two wireless security options supported by the Gateway: WPA Personal and WEP. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent Privacy.) These are briefly discussed here. For detailed instructions on configuring wireless security for the Gateway, turn to “Appendix B: Wireless Security.” If you want to disable wireless security, select Disable from the drop-down menu for Security Mode.

WPA Personal. Enter a WPA Personal of 8-32 characters. Then enter a Group Key Renewal period, which instructs the Gateway how often it should change the encryption keys.

Figure 5-15: WPA Personal

Chapter 5: Configuring the Wireless-G ADSL Home Gateway The Wireless Tab

Wireless-G ADSL Home Gateway

WEP. WEP is a basic encryption method, which is not as secure as WPA. To use WEP, select a Default Key (this indicates which Key to use) and a level of WEP encryption, 64 bits 10 hex digits or 128 bits 26 hex digits. Then either generate a WEP key using a Passphrase or enter the WEP key manually.

• WEP Encryption. An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode data transmissions, all devices in a network must use an identical WEP key. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption, they may decrease network performance. To enable WEP, select 64 bits 10 hex digits or 128 bits 26 hex digits.

• Default Transmit Key Select which WEP key (1-4) will be used when the Gateway sends data. Make sure that the receiving device (wireless computer or client) is using the same key.

• Passphrase. Instead of manually entering WEP keys, you can enter a passphrase. This passphrase is used to generate one or more WEP keys. It is case-sensitive and should not be longer than 32 alphanumeric characters. (This Passphrase function is compatible with Linksys wireless products only and cannot be used with Windows XP Zero Configuration. If you want to communicate with non-Linksys wireless products or Windows XP Zero Configuration, make a note of the WEP key generated in the Key 1 field, and enter it manually in the wireless computer or client.) After you enter the Passphrase, click the Generate button to create WEP keys.

• WEP Keys 1-4. WEP keys enable you to create an encryption scheme for wireless network transmissions. If you are not using a Passphrase, then manually enter a set of values. (Do not leave a key field blank, and do not enter all zeroes; they are not valid key values.) If you are using 64-bit WEP encryption, the key must be exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, the key must be exactly 26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.
