Overview of the SMC7301TA ISDN

Router

The SMC7301TA ISDN Router is a small desktop router that sits between your local Ethernet network and a remote network (For example, the Internet or a remote office). The SMC7301TA contains an ISDN S/T interface, a 10Mbps WAN port, a 10/100Mbps LAN port, and a conso le port for management capability. Data comes into the SMC7301TA from the LAN and then is “routed” to the remote network, and vice versa. In addition to its capability to route IP traffic, the SMC7301TA also acts as a bridge for other network protocols , such as Appletalk or SNA.

SMC7301TA Applications

The main functions of the SMC7301TA are to support devices on your LAN to access the Internet, to support remote users to dial -in and access resources on your LAN, and to support communications among branch

offices.

Accessing the Internet

The most common use for the SMC7301TA is to provide Internet access, so that everyone on your LAN can surf the web, send/receive e -mail, or share files. The SMC7301TA automatically acquires the necessary IP addre ss when the connection to the Internet is established. You don’t need to apply for or assign an IP address to each PC or workstation on your network. There are two alternatives in establishing the connection between the LAN and the Internet: either thr ough ISDN or through an xDSL/cable modem. With built-in PPPoE (Point-to-Point Protocol over Ethernet) support, the SMC7301TA provides virtual dial -up environments and allows end users to connect via an xDSL/cable modem to the Internet whenever they wan t. Alternatively, end users can connect via an ISDN connection to the Internet. In this situation, the SMC7301TA supports “bandwidth on demand”. For example, any user’s initial intent to access the Internet will trigger a B-channel connection to be se t up. As the traffic builds (for example, more users try to access the Internet, or the same user generates a lot of traffic), the SMC7301TA will establish the second connection through the other B-channel. As traffic decreases, one B -channel will be taken down, until finally, after a configurable period of inactivity, the remaining B -channel will also be disconnected.

Supporting Dial-in Access to Your Network

Under an ISDN connection you can set up your SMC7301TA to allow users to connect to your ne twork and share resources from their homes while

they are traveling. The SMC7301TA’s built -in “Broadband Router Manager” makes the necessary setup a snap. As a security feature, after a user calls in, the SMC7301TA will hang up and call that user back at a pre-configured telephone number.

Creating Your Own Private Wide Area Network

Under an ISDN Connection you can also create your own private wide area network with the SMC7301TA and allow two or more remote networks to connect to one another and share resources. The remote network can use an ISDN router from a different vendor - as long as it also supports LAN -to-LAN communication.

Security Overview

More and more people are concerned about security of their data in this Internet era. The SMC7301 TA provides many ways to help make your network and your data secure:

 All dial-in users and LAN -to-LAN communications require

CHAP/PAP/MS-CHAP authentication (basically, user name and

password).

 SMC7301TA also supports call back for dial -in users so that remote

users are really who they say they are.

 ISDN Caller ID may be used for incoming call authentication.  SMC7301TA uses a private IP addressing scheme to prevent devices

on your LAN from being accessed by users on the Internet.

 Console and Telnet Configu ration provide password protection.  IP packet filtering may be used to enhance security requirements.

Chapter 2 Installing the

SMC7301TA

Hardware Installation

Follow these steps to complete the hardware installation for the SMC7301TA:

 Connect the SMC7301TA from the WAN port to an xDSL/cable modem,

or attach an ISDN line to the ISDN port (S/T interface).

 Connect your PC to the RJ -45 LAN port. Two or more PCs can be

connected via a multi-port hub or switch which you can connect to the RJ-45 LAN port of the SMC7301TA.

 Plug the power adapter into a wall outlet and the AC connector on the

back of the SMC7301TA.

 The RS-232 port is only used to connect a terminal to run the

Command Line Interface using the null modem cable. (This is an

optional connection.)

 There is a DIP switch located on the rear panel for setting the

terminating resistor. You only need to adjust this switch if ther e are two or more external ISDN equipment attached to the local telephone line.

Setting Up a Windows PC

This section describes the configuration required by LAN -attached PCs which communicate with the SMC7301TA, either to configure the SMC7301TA, or for network access. These PCs must have an Ethernet interface installed properly, be connected to the SMC7301TA either directly or through an external hub or switch, and have TCP/IP installed and configured to obtain an IP address through a DHCP server. Directly connect a Windows 95/98/2000 PC to the SMC7301TA. If TCP/IP is not already installed, follow the steps below for its installation.

Note: Any TCP/IP capable workstation can be used to communicate with or through the SMC7301TA. To configure oth er types of workstations, please consult the manufacturer’s documentation.

Step 10: With the SMC7301TA powered on and connected to the LAN, reboot the PC. After the PC is re -booted, you should be ready to configure the SMC7301TA. See Chapter 3.

Chapter 3 Internet Access

Configuration

Once you have completed the installation stage and have configured PCs in the way described in chapter two, you are ready to configure the SMC7301TA for actual applications. This chapter describes how to configure you’re SMC7301TA for basic Internet access, as well as Internet access with advanced features. In the following sections you will be shown how to configure the SMC7301TA for basic Internet acce ss in less than five minutes using the web-based “Broadband Router Manager”.

Using Different Browsers to

Configure the SMC7301TA

To configure your SMC7301TA, you can use popular browsers such as Netscape 4.x and Internet Explorer 4.x and 5.x. The fol lowing describes how to access the “Broadband Router Manager” through IE or Netscape Navigator.

Netscape Navigator 4.x:

In the Location box (where you normally enter the URL address), enter

the default private IP address of SMC7301TA followed by hitt ing the return key: http://192.168.2.1

Internet Explorer 4.x and 5.x:

In the Address box (where you normally enter the URL address), enter the default private IP address of SMC7301TA followed by hitting the return key: http://192.168.2.1

Logging On

A password screen will ask you to log on after you enter the default IP address described above. If you are logging on for the first time, you should accept the factory default password (which is “password”). The password is always displayed as a string of asterisks (“*”). Clicking the Log On button will begin the Configuration process for the SMC7301TA.

The next time you log in, even if you have modified the password, the default password (“password”) will still be us ed as the default. You need to change it to the correct password before you will be let in. No matter what password you use, each character will always be displayed as a “*”. If you forget the password, you need to follow the steps described later in the chapter to be able to log on.

After clicking Log On, the following screen will display, and you must select either ISDN or WAN as the interface for Internet Access. Click Next to proceed in the configuration process. Please see the following text for de tails.

Customizing the User Interface to

Fit Your Specific Needs

When you enter into the main configuration window, click “ Customize User Interface” in the SYSTEM TOOLS Menu on the left side of the screen, this will allow you to customize the Broadband Router Manager to suit your own specific needs. The selections you make determine what configuration menus and buttons will appear in the screen. For example, if you select Basic Internet Access only, the interface will only displa y buttons that you need for basic Internet access. If you subsequently use Broadband Router Manager to configure the SMC7301TA for other applications, you can return to this screen to “re-customize” your interface by selecting Customize User Interface from the SYSTEM TOOLS Menu.

Basic Internet Access

Select this option if you need basic Internet access. This will enable you to configure Internet Access for all of your LAN users. There are two Internet access interface selections provided by the SMC7301TA: through ISDN or through WAN.

Internet Access with Advanced

Configuration

Select this option if you want to configure advanced options, such as changing the private IP address (for example, when you intend to create your own private WAN between multiple SMC7301TA routers), or adding a public IP address (e.g., when you want to install servers on the LAN which are accessible from the Internet).

Access to/from Remote Site (e.g., Branch Office)

Select this option if you want to create connec tions to other LAN sites, that is, users at each site can share resources. If you use Windows PCs, for example, then from the Network Neighborhood facility, you can access files from remote PCs directly. This feature is valid only when you select ISDN as

the interface for Internet access.

Dial-in Access for Off-Site Users

Select this option if you want to allow users on a stand -alone computer to dial in and access resources on your network. This feature is valid only when you select ISDN as the interfa ce for Internet access.

Click Next when you have selected the options you want. The quantity of selections is not limited but step -by-step configuration is recommended.

Overview of Broadband Router

Manager Screen

Before you begin the configuration process, take a moment to look at the Broadband Router Manager screen. Look for these areas:

 Menu Window (in the left side of the screen)  Configuration Window (in the right -upper side of the screen)  Message Window (in the right -lower side of the screen)  System Status Monitoring Window (the separate window)

Menu Window

This part of the browser screen contains items you can click to display the various screens for configuring your SMC7301TA.

Configuration Window

This is the window where the actual configuration screens appear.

Message Window

Whenever appropriate, the SMC7301TA will display system status or error messages in this window. For example, when you try to connect to the Internet, if you had configured your password incorrectly, the message window will display an appropriate message.

System Status Monitoring Window

This section displays statistics and the status of all interfaces. This window is invoked as a separate browser screen from the main Broadband Router Manager browser screen and appears automatically each time you start Broadband Router Manager . If you close this window, you can always restart it by clicking System Status in the MONITORING Menu. It does not contain any toolbars or browser menu buttons. Although the main Broadband Router Manager screen will timeout, this screen will not, and will continue to be operational as long as it is active.

The following statistics are reported for each interface: Device: lists all interfaces, including both the physical interface as well as logical connections that have been activated (such as connections to the Internet or to remote offices). Status: indicates the current state of the interface: For the LAN, Up means that the interface is up and functioning, Down means that this interface is not connected. For WAN or ISDN B channels, if the interface is active, the profile name is displayed. NoCall means an ISDN B1 or B2 channel is idle. Xmt Pkts: indicates the number of packets th at have been transmitted through the interface.

Rcv Pkts: indicates the number of packets that the interface has received. Err Pkts: indicates the number of error (bad) packets that have been

received. Disconnect: if an interface has been selected (highlig hted), clicking this button will cause the connection to be taken down. The LAN interface and the ISDN physical line are not affected by this operation. Clear: resets the selected statistic values to zero.

What is a Connection Profile?

To access the I nternet via PPPoE, you need to apply for an account with an ISP (Internet Service Provider), who will provide you a username and password that the ISP will use for authentication purposes and will also

provide all necessary information such as WAN IP Addr ess, Netmask, ISP Gateway IP Address, DNS IP Address. Alternatively, the SMC7301TA users can select to access the Internet via ISDN, which you need to apply for an account with an ISP (Internet Service Provider). The ISP will provide you with a username and password that the ISP will use for authentication purposes, and will also provide telephone numbers for dialing -up.

You need to enter such information into a “connection profile” in the SMC7301TA. Likewise, a connection profile needs to be created fo r each dial-in user, or for each remote office.

Essentially, a connection profile contains all the information that the SMC7301TA needs to access the Internet for LAN users, or to support a remote dial-in user, or to set up a connection with a remote o ffice. Such information includes dial -up phone numbers, authentication information (the local user name and password, and possibly the remote site user name and password), plus other information that may be required for the communication.

Basic Internet Access Configuration

via WAN

This section describes the steps to set configuration for Basic Internet Access via WAN. You will find that the SMC7301TA is optimized for Basic Internet Access. You don’t need to understand, to apply for or to assign an y IP addresses in your entire network. The SMC7301TA does these things for you automatically. You need to configure each device on your LAN in a uniform way as described in Chapter 2. What is Basic Internet Access? It means accessing the Internet, surf ing the web, accessing a remote FTP server (to send or receive files), and sending and receiving e -mail. These are the tasks that users perform most. When you apply for an account with your Internet Service Provider (ISP), you will be given the username, password, and other necessary information. Follow the steps below.

Step 1: When you logon, select Customize User Interface in the SYSTEM

TOOLS Menu. Accept the Basic Internet Access selection and click Next. The following window will be displayed , and select “ I use Internet access

Note: When you click Apply and Test, the SMC7301TA attempts to place a call to your Internet Servi ce Provider and log in. Watch the Message Window for any messages. After the test is successful, the SMC7301TA will disconnect from your ISP. If it is not successful, make any necessary changes based on progress messages that appear in the message window, and try again.

After Apply and Test is successful, any users on your LAN who want to access the Internet should configure their PCs or workstations in the way described in Chapter 2. Then, they must reboot their workstations in order to update them with information that the SMC7301TA learned from the ISP during the Apply and Test operation.

IP Configuration for Internet Access

Using the IP option in the Menu Window, you can assign a public IP address to the SMC7301TA, modify the private IP addre ss of the SMC7301TA, modify DNS addresses, and enable or disable DHCP.

Step 1: Select Internet Access with Advanced Configuration from Broadband Router Manager . Then click IP from the Menu Window. Step 2: The System IP Configuration screen appears:

Note: To install public servers on your network (For Example, Web or ftp servers), you need to apply for an IP address for each server plus one for the LAN port of the SMC7301TA. All these public IP addresses have to belong to the same IP network.

Set the following parameters: Public IP Address: the public IP address for the LAN interface on the SMC7301TA. Public IP Netmask: the network mask for the public network address on your LAN. Private IP Address: the private IP address for the LAN interface on the SMC7301TA. The default private IP address is 192.168.2.1. If you want to create your own private network through other SMC7301TA with remote offices, you need to make sure that each SMC7301TA on each LAN is assigned a unique private IP net work address. However, please note that once you change the private IP address (such as from the default of

192.168.2.1 to 192.168.1.1) either from the browser or through a telnet session (which is based on the IP address), the device from which you operate will no longer be able to communicate with your SMC7301TA. To reconnect, you need to restart your device to allow it to acquire the new private IP address from the SMC7301TA, and then your device can again communicate with your SMC7301TA. For the same re ason, all devices on the

LAN need to be restarted before they can access the Internet again. Private IP Netmask: the network mask for your private network. Its value is

255.255.255.0, and cannot be changed. Primary DNS IP Address: the IP address of the pri mary Domain Name Server (DNS). If properly configured, when a device reboots and acquires the IP address from the SMC7301TA, the IP addresses of both the primary and the secondary DNS server will be provided for client workstations or PCs. Secondary DNS IP Address: the IP address of the secondary domain name server.

Note: When an SMC7301TA connects to the ISP, it will automatically be assigned the IP address for a primary Domain Name Server (DNS) , as well as the IP address for a secondary DNS. Alternative ly, the user can decide to assign their own DNS IP addresses.

DHCP: enables or disables the SMC7301TA’s Dynamic Host Configuration Protocol (DHCP) feature. If you want the SMC7301TA to act as a DHCP server and assigns private IP addresses to any requestin g DHCP client, make sure DHCP is enabled. When enabled, the SMC7301TA will provide an IP address, network mask, gateway address (SMC7301TA’s private IP address), and DNS addresses to any workstations on the local area network that are configured as a DHCP client. Devices on your network that are configured with public IP addresses are not DHCP clients. Therefore, you need to assign their IP addresses, network mask, default gateway IP address, primary and secondary DNS IP addresses manually. IP Address Assignment-High & Low: the maximum and minimum private IP address which can assigned to each client PC or workstation in the LAN. The range is from 1 to 254.

Step 3: Click Routing, Address Translation or Static DHCP if it is necessary to set these configurations. Otherwise click Apply to confirm the configuration and return to the main configuration screen.

The IP Routing Table

The IP Routing Table contains all the information that the SMC7301TA needs to route an IP data packet. You can view the IP Routi ng Table by

clicking on the Routing button at the bottom of the Advanced Internet Access Setup screen (described in the previous section). From this screen, you can also add new routing entries to the table. The following screen shows an example of the IP Routing Table.

When an IP packet arrives in the SMC7301TA, IP tries to determine if the destination IP address contained in the packet is within the network defined by the “Dest IP” and “Netmask” pair of an entry in the routing tab le. If a match is found, the packet is forwarded to the interface or profile specified in the “IfName” field. The “Hops” field is the number of routers the packet must travel through in order to reach its final destination. If this value is zero, the destination is in a network directly attached to this router, such as a LAN. If no match is found with a destination network, then a special entry called the “Default IP Route” is used. This normally is set to a path where another router can be reached that has additional information about other networks not known to the Broadband Router, such as the interface to the Internet. If no match is found and a default IP route is not defined, the IP packet is discarded and will go nowhere. An entry for a specif ic host or network may be added manually. This “Static Route” is indicated by an “S” in the Flag’s field. Other flag field entries are “H” for host, and “G” for gateway.

Note: To delete a static route, select it in the routing table and click the Delete button. You cannot delete Host or Gateway routes.

Follow the steps to add or to change the default route or add a static route: Step 1: Click the Add button in the IP Routing Table screen to display the following screen:

Step 2: Enter the following information: Default Route: select if you want to specify a new default route. Note that the

Remote IP Address and Remote IP netmask fields do not appear if you select this option. CAUTION: Misconfiguring the default route may result in abnormal system behavior and/or unnecessary telephone charges.

Static Route: select if you want to add a static route. Remote IP Address: the remote IP address of the new route. Remote IP Netmask: the IP netmask of the new route. Gateway: identifies if the gateway is an IP address or interface. Hop Count: the maximum number of hops for this route. Step 3 Click APPLY.

IP Address Translation

Configuration

For security and economic purposes, the SMC7301TA supports Single User Account feature (SUA). Multiple users in the LAN can share a public IP address from an ISP, and the whole LAN will be viewed as a big “device” by Internet users. However, servers in the LAN are allowed to provide services to the Internet users if you properly configure the server’s p rivate IP address “translated” to the corresponding service port number. For example, you can set the FTP server’s private IP address mapped to port 21. Follow the steps and the SMC7301TA will automatically complete the mapping procedure.

Note: Remember to set a fixed private IP address for each server providing services to the Internet users, i.e., these servers can’t be DHCP clients.

Add or Edit an IP Address Translation

Step 1: Click Address Translation button in the Advanced Internet Access

Setup screen. The following IP Address Translation Configuration screen will appear.

Step 2: Click Add for adding an IP address translation, or click Edit for editing an existing IP address translation after selecting the IP address translation that you want to edit. The Following screen will appear.

Step 3: Enter the following parameters. Add Address Translation: Available options are Default Enter and Static

Entry. Public Port Number: The public port number corresponding to the service that the specific server provides. Private IP Address: The private IP address that you want to assign to the server. Private Port Number: The private port number corresponding to the service that the specific server provides. Public Port Number and Private Port Number should be the same.

Step 4: Click Apply.

Delete an IP Address Translation

Step 1: Select the IP address translation that you want to delete from the IP

Address Translation Configuration screen.

Step 2: Click Edit.

Static DHCP Configuration

By the built-in DHCP feature, the SMC7301TA can automatically assign a private IP address to each PC or workstation in the LAN. But under some situations, you need to set a static private IP address for certain PCs or workstations. Follow the steps to as sign a static private IP address to a PC or a workstation.

Note: Remember to properly set network configurations from the operating systems on the PCs or workstations to whom you want the SMC7301TA to assign a static private IP address.

Add or Edit a Static Private IP address

Step 1: Click Static DHCP from Advanced Internet Access Setup Screen. The

following screen will appear.

Step 2: Click Add for adding a static private IP address, or click Edit for editing an existing static private IP address afte r selecting a new static private IP address. The following screen will appear.

Name: A name is assigned for router manager identification purpose. IP Address: The static private IP address that you want to assign. MAC Address: The MAC address of the physical interface between the

SMC7301TA and the PC or workstation.

Step 3: Click Apply.

Delete a Static Private IP address

Step 1: Select a static private IP address that you want to delete form the

DHCP Configuration window.

Step 2: Click Delete.

Chapter 4 Remote Office

Access Configuration

In order for the local LAN users to access a remote LAN, you need to configure a connection profile for the router on each site (the remote router and the Broadband Router). Note that the remote site does not have to have a SMC7301TA router, and may not be configurable by the local administrator. In either case , make sure the configuration of SMC7301TA matches the requirements of the remote site.

Remote Office Access by ISDN

To configuring the ISDN interface for Remote Office connectivity, follow these steps:

Step 1: Select Access to/from Remote Site in the Broadband Router Manager screen and click Next:

Step 2: If you have already conf igured your ISDN interface, skip to Step 3.

Otherwise, configure your ISDN interface in the way described in the chapter

Step 3: Click Connection Profiles in the Menu Window. The Connection Profile Summary window will appear if there was connection prof ile

configured previously.

Step 4: Select New and Click Next , the Connection Profile Configuration window should appear as follows,

Step 5: Enter the following information : Profile Name: a name associated with this profile. Call Direction: if the remote site will be dialing in, select Incoming. If the

SMC7301TA will dial out to the remote site, select Outgoing. Select Both if either side can initiate the connection. The default setting is Both.

Note: If you set Call Direction to Incoming, the Remote Phone Number, My System Name, and My System Password fields will not display unless Call Back is Yes. If only incoming calls are allowed with this profile, the APPLY and TEST button will not display. If you set Call Direction to Outgoing, the Call Back fields will not display.

Call Back: if Call Back is enabled ( Yes is selected), the SMC7301TA checks the Remote System Name and Remote Password. If a call is received and authentication succeeds, the SMC7301TA disconnects the incoming call, and calls the number in the Call Back field. If Call Back is not enabled (No), the Call Back Number field will not display. If the Call Direction is Outgoing only, Call Back options will not display. Remote Phone Number: the ISDN phone number of the remote router

connected to the remote LAN. My System Name: the name that the remote system will use to recognize your network. This field is case sensitive. My System Password: the password the remote system will use to authenticate your system. This field is case sensitive.

Note: Make sure the remote site is configured with the same values you specify in My System Name and My System Password .

Remote System Name: the name of the remote network that will dial in. This field is case sensitive. Remote System Password: the password that your SMC7301TA will expect to see from the remote system. Note that authentication is CHAP, PAP, or MS-CHAP, meaning that CHAP will be used to authenticate the incoming call first. If CHAP fails, then PAP will be used. If PAP fails again, then MS -CHAP will be used.

Step 6: If you selected Outgoing or Both as your Call Direction, click APPLY and TEST, or select ADVANCED for more options. You must still click Apply and Test even if the other end of the connection has not been

configured. In this case the test will fail, but that can be considered normal.

Note: When you click APPLY and TEST, the SMC7301TA attempts to place a call to your remote site and log in. Watch the Message Window for any progress messages. After the test is successful, the SMC730 1TA will disconnect from your remote site. If it is not successful, you can make any necessary changes based on progress messages that appear in the message window, and try again.

Caller ID Authentication: select Yes if you want the SMC7301TA to check the caller ID before accepting the call. This service may require a special agreement with your ISDN service provider. Caller ID Number: if you enabled Caller ID Authentication, enter the expected Caller ID Number in this field. STAC Compression: allows outgoing data to be compressed to achieve higher throughput, and compr essed incoming data to be recognized. The ability to use compression depends on the capabilities of the ISP. Idle Timeout: the number of seconds of inactivity over the connection. When this value is reached, SMC7301TA will disconnect the call. You can set the idle timeout from 0 to 3600 seconds. The default setting is 120 seconds. If you select 0, the connection will never be timed out.

Enable IP: select Yes to allow IP routing over a connection using this profile. IP RIP: enable or disable IP Routing Infor mation Protocol. Available RIP

options are RIP1 and RIP2 Remote IP Address: the IP address of a destination computer on a network reachable through this connection.

Remote IP Netmask: the IP subnet mask of the Remote IP Address. Enable Bridging: select Enable to bridge other protocols, for example, SNA,

Appletalk, and NetBEUI. Step 2: If advanced configuration is required for the operation of ISDN, and its load sharing capabilities, then click Multilink. Alternatively skip to step 4.

Step 3: Click OK after completing the parameters in the following windows.

Multilink Usage: determines how the SMC7301TA utilizes the two B channels

in your ISDN connection. Options are: One B Channel Only: SMC7301TA will only use one B channel, regardless of the traffic. Two B Channels Only When Needed: SMC7301TA will initiate a connection with one B channel, and only bring up the other B channel if the traffic increases beyond the capacity of the first B channel. Always two B Channels: SMC7301TA will always use both B chan nels, regardless of traffic.

Depending on the selection of the ISDN link usage, the following options may be offered. Upper utilization threshold: determines when the SMC7301TA will activate the second ‘ B’ channel. Lower utilization threshold: determines when the SMC7301TA will drop the second “B” channel call. Optional 2nd Remote Phone Number: required if the remote site requires two separate numbers for dial in access.

Step 4: Skip to step 6 or click Alternative Numbers if it is required to set more than one choice of remote phone numbers. The screen will appears as follows,

Step 5: Select the Number of the Alternative Remote Phone Numbers and then enter the remote phone numbers in the corresponding blanks. Click OK to go back to the previous screen.

Step 6: Click OK to go back to the main configuration screen and click Apply and Test.

Note: When you click APPLY and TEST, the SMC7301TA attempts to place a call to your remote site and log in. Watch the Message Window for any progress messages.

Chapter 6 Packet Filtering

Configuration

This chapter covers IP packet filtering configuration of the SMC7301TA.

Note: Packet filtering is a sophisticated feature that can substantially impact your SMC7301TA operation. Therefore be sure that you fully understand the descriptions in this chapter before you start to configure and use this feature. This is because if you make any mistakes, it may produce drastic and potentially undesired results.

IP Packet Filtering Overview

The SMC7301TA already provides you with many different ways to ensure the security of your data in your local environment. For example, the concept of single IP address and private networking means devices on your network can access the Internet, but not vice versa. This feature has proven to be useful and effective to most users. However, for some users, additional security requirements may exist, which can be satisfied by this packet filtering feature. Packet filtering is a security feature that allows you to s electively pass or throw away data traffic between your local LAN and the wide area network (For example, the Internet). Specifically, it allows you to define:

 each and every IP packet to be inspected to determine if it should be

allowed to be transmitted over a WAN interface, or alternatively,

 each and every IP packet to be inspected to determine if it should be

disallowed from being transmitted over a WAN interface.

Due to the conflicting nature of allow and disallow, only one of the above two choices can be made for each WAN interface. After the choice is made, you can define selection rules to “select” which packets will be allowed (or disallowed). Each selection rule consists of:

 a set of local IP addresses/ports, plus  a set of remote IP addresses/ports,

Note: IP addresses can be a single IP address, a range of IP addresses, a network address, or any IP address. Port numbers can be a single port number, a range of port numbers, or any port number.

Therefore packet filtering simply defines specific sets of rules of what to allow or disallow through a set of parameters as highlighted below:

 remote devices with IP addresses/port numbers are allowed (or

disallowed) to communicate with local devices with IP addresses/port numbers over a WAN connection.

Examples of packet filtering requirements are:

1. “I want to block any outside user from being able to telnet into my web server”.

2. “I want to disallow people in the manufacturing department to access the Internet“.

The corresponding “transla ted” packet rules are:

1. Remote devices with ANY IP address/port number are disallowed to communicate with the local web server (identified by its IP address and the HTTP port number ) over my Internet connection .

2. Remote devices with the range of IP addresse s in the manufacturing department and any port number are disallowed to communicate with any IP address/port number over my Internet connection.

Adding/Editing/Deleting a Packet

Rule

To add a new packet rule or to edit an existing one, select IP Filter from the Configuration Menu. Then IP Filtering Configuration window will appear.

Step 1: From the IP Filtering Configuration screen, select the WAN profile of interest from the pull down menu. For example, if your only need is to access the Internet, you should only select the Internet access profile. Step 2: Select send or discarded as desired, which is equivalent to allow and disallow, respectively. Step 3: If you are just starting, click Add to add a new selection rule. If you have previously defined rules, you will see those rules shown as entries in the rule table, and you can edit the rule by first highlighting the desired entry in the rule table followed by clicking the Edit button. Step 4: In case of adding a new selection rule, the foll owing screen shows.

Enter the following information:

Rule No.: a number used for identification purposes. Rule Name: a name by which you will refer to this rule. Interface: the specific WAN interface this new selection rule will apply to. IP Protocol: The IP protocol that this new selection rule will apply to. Available options are Any, TCP, UDP, ICMP, and IGMP. Local IP Address: the IP address(es) of the local devices this new rule will apply to. You can select a single IP address, a range of IP addresses, a network, or any IP addresses. The screen may change to show fields you

need to fill out accordingly. For example, if you select a range, you will also see (From) and (To) fields where you need to fill out the starting IP address and the ending IP address.

Local Port: the port number(s) of the local devices this new rule will apply to. Remote IP Address: the IP address(es) of the remote devices this new rule will apply to. You can select a single IP address, a range of IP addresses, a network, or any IP addresses. The screen may change to show fields you

need to fill out accordingly. For example, if you select range, you will also see (From) and (To) fields where you need to fill out the starting IP address and the ending IP address. Remote Port: the port number(s) of the remote devices this new rule will apply to. A If you highlighted an existing entry in the IP Filtering Configuration window and clicked Edit instead, a similar screen will display, with all fields already filled out previously. Then you can make changes if necessary. If you highlighted an existing entry and clicked Delete instead, the corresponding entry in the rule table will be removed.

Chapter 7 Managing the

SMC7301TA

This Chapter contains the following sections which cover management of the SMC7301TA:

 How to view the connection log?  How to upgrade my SMC7301TA firmware?  How to save or clear my configuration changes?  How to reset my system?  How to change my Broadband Router Manager password?  What if I forget the Broadband Router Manager password?  How to configure general system settings?  How to use Command Line Interface?

How to View the Connection Log

The SMC7301TA provides a connection log that you can use to track the telephone connections in and out of your SMC7301TA. Connect and disconnect messages can be useful in determining your telephone costs, and trigger messages are useful in determining which applications and tasks trigger a connection. These messages contain the IP address of th e PC, which caused the connection to be established, as well as the port number or

application name. To view the Connection Log, select Connection Log from the Monitoring Menu. The Connection Log Window will appear.

There are three types of mess ages that appear in the Connection Log: Connect and Disconnect messages: Shows the date, time, and port (channel) when a connection is completed or disconnected. Trigger messages: Shows the date, time, channel, duration, and details of an event that triggers a connection.

How to Upgrade the SMC7301TA

Firmware

You can also upgrade your SMC7301TA firmware (the software that controls the router’s operations). Normally, this is done when you discover a problem which is resolved in a different version o f firmware, or when SMC produces a new software version that contains new features that you need. Otherwise, if you are happy with your current unit, you may not want to upgrade even if a new version is available. A firmware upgrade can be performed through the Broadband Router Manager as follows:

Step 1: Select System Upgrade from the Menu Window. The following screen is displayed:

Step 2: To update the SMC7301TA firmware, download the firmware from SMC’s web site and install the firmware in your local environment first, then from the above screen enter a path or filename, or click Browse to select a path to the firmware. Next, Click the Upgrade button below the file name and follow the onscreen instructions. The new firmware will begin loading across the network. After the operation is complete, be sure to reset the system to have the new firmware take effect.

How to Save or Clear Configuration

Changes

Every 30 minutes, the SMC7301TA automatically saves configuration changes that are unsaved. You can use the Configuration Data Options from System Tools Menu to manually save changes or clear the configuration completely. You should do this after every configuration action. Step 1: Select Configuration Data Options from the System Tools Menu. The following screen displays:

Step 2: Select Save to save, or Clear and Reset to erase your entire configuration database and reset the system. Step 3: When you click Clear and Reset, you will be asked to confirm your choice.

Click Yes to clear the configuration and reset the system, or click No to cancel.

How to Reset SMC7301TA

You can reset the system from the System Tools Menu or by unplugging and plugging back in the power connector to the SMC7301TA. Follow the steps to reset the system:

Step 1: Select Reset System from the System Tools Menu. The following screen displays.

Step 2: Click YES to reset the SMC7301TA.

Note: Resetting the SMC7301TA will disconnect any active calls, and may disrupt current user operations. You may also lose recen t configuration changes (those that have been made within the last 30 minutes) unless you manually save the configuration (see the previous section). All saved configuration changes are restored after the system re -initializes.

How to Change the Broadband

Router Manager Password

After you start using the SMC7301TA, you should change the factory default password. Follow the steps to change the password.

Step 1: Select Change Password from the System Tools Menu: The following screen displays:

Step 2: Enter the following information: Current Password: the current password for theSMC7301TA. New Password: the new password for the SMC7301TA Confirm Password: the new password for the SMC7301TA, entered again

for confirmation.

Note: If you are changing the password for the first time, the Current Password is “password”.

Step 3 Click Submit.

What if I Forget the Password

If you forget the Broadband Router Manager password, the only way to recover it is to clear the entire configuration and return the u nit to its original state as shipped from the factory. Unfortunately, this means that you have to re-enter all of your configuration data. To clear the configuration and restore the password to the default, follow these steps:

Step 1: Using the supplied Null Modem Cable, connect a console (or a PC running a terminal emulation program such as HyperTerminal) to the SMC7301TA Console port. The default port settings are 19200, N, 8, 1, no flow control. Step 2: Turn off the SMC7301TA, then turn it on again. In the console window,

you’ll see the message “Loading firmware...”. Step 3: When you see the message "Ready", immediately (within one second) press Ctrl+C. Step 4: The SMC7301TA resets. When this is complete, the SMC7301TA will return to its factory defa ult settings. The password will once again be “password”.

Note: Keep in mind that anyone can perform this procedure and seriously compromise security in your network. Make sure physical access to the SMC7301TA is consistent with your security requirements .

How to Configure General System

Settings

To view or change general system settings, select System from the

Configuration Menu. The following screen displays:

Step 1: Enter the following information: System Uptime: the elapsed time since the SMC7 301TA was powered on. System Name: a unique name that you assign to the SMC7301TA. System Contact: the network administrator responsible for maintaining the

network.

System Location: where the SMC7301TA is physically located.

Step 2: Click Apply.

Using the Command Line Interface

If you prefer, you can configure the SMC7301TA using a command line interface (CLI). There are two ways to connect to the SMC7301TA’s CLI:

• telnet,

• direct PC connection running terminal emulation software.

Connecting to the CLI With Telnet

If you are on the network, you can use Telnet to connect to the CLI. Use any telnet program (or from Windows 95/98, select Run for the Start menu, and enter “telnet” followed by the IP address), and connect to 192.168.2.1 (or the new private address if you have changed it). You will see the following prompt: Manager Console Version: <revision number, build date and time> Please enter your password: Enter the current pa ssword (which is the same as the browser password) and the command prompt displays: Command>

Connecting to the CLI through the Console Port

Another way to invoke the command line interface is to connect the console port on the SMC7301TA to a PC running the terminal software. In the box, you’ll find a null modem cable that you can use to connect your PC (usually the COM2 port) to the SMC7301TA console port. Connect to the CLI with a termina l program such as Hypercritical or Proclaim. Set your COM port parameters to 19200, N, 8, 1, with hardware flow control disabled. If your program does not allow you to set flow control options, set it in the Device Manager area of the Windows System settin gs (accessible from the Control Panel). Note that after configuring these settings, some programs require that you close the application and re -open it. Enter a carriage return to start your session, and you’ll see the following prompt: Manager Console Version: <revision number, build date and time> Please enter your password: Enter the current password (which is the same as the browser password) and the command prompt displays.
