Web User Interface

Overview

The Web User Interface (WUI) is one of three router user interfaces. The other interfaces
are the Terminal User Interface (TUI) and Command Line Interface (CLI). Each interface
allows you to set up, modify, and view router configuration variables and operational data.

The Web User Interface is a system of graphical menus. Menu pages control router
parameters and provide information about them. The WUI organizes these router
parameters into six topics. Here are the six topics, in the order that the WUI displays them...

• Quick Setup • Firewall Settings

• Service Provider

Settings

• Tools

• Network Settings • Statistics

This part of the manual discusses all but the Quick Setup topic. You’ll find information on
using the Quick Setup feature in the Quick Installation Guide.

This manual begins topic discussions with a picture of the top-level menu screen. A
description of screen terms and procedures follows each screen shot. Either text or a table
defines screen variables. Afterward, summarized, step-by-step procedures often follow.

Selecting Topics. When you look at a menu page, notice the divider tabs at the very top of
the page. You can access any of the six router configuration and information topics by
clicking on its tab. The graphic below portrays the six divider tabs as they appear on a
menu.

ADSL Standard

The ADSL Standard menu configures the ADSL protocol. You’ll find four supported
protocols: Multi-mode, T1.413, G.dmt and G.lite. Your ISP determines the protocol to use.
In most cases, Multi-mode should allow a connection to the ISP.

PPPoE Relay

PPPoE Relay protocol supports multiple PPPoE sessions through the router, on a LAN
interface, over an RFC1483 Bridged PVC. The router supports multiple sessions by
maintaining a mapping table. In this table, each entry represents one session. The Client /

file:///P|/T_WRITER/Documentation/Released/900...ide/9003%20(Guiness)%20prac%20template/wui.htm (5 of 55) [11/6/2002 8:53:37 AM]

U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide

Server side MAC address and the Session Id provide the basis for the mapping. Refer to
WAN setup instructions on configuring PPPoE. The PPPoE Relay option requires an ATM
PVC (server) and a LAN interface (client). The client initiates a PPPoE session with the
server via a third-party PPPoE client. Follow these steps…

1. Configure the client and server.

2. Click Enable to start the relay function.

NAPT Bridge

This screen provides the option of enabling or disabling MER PVC. From this screen, you
can also change this PVC’s ATM values. The MER Interface is an RFC1483 Bridged PVC,
terminated in the router with a static public address. The ISP provides the static public
address. This type PVC operates with Network Address Translation (NAT) and DHCP.
These protocols allow the router to serve LAN users with private addresses.

Use LAN Setup to set the router’s IP Address and Subnet Mask. The LAN IP address
allows you to connect the router to your LAN. This address also allows you to manage the
router from your LAN. A LAN (Local Area Network) connects computers in the same
building or area.

Subnet masks split one network into a set of mini networks or subnets. Subnetting helps to
reduce traffic on each subnet. Subnetting also makes the network more manageable. Each
subnet functions as if it were an independent network.

To set up the LAN…

1. Enter the LAN IP Address for the router to use on the network.

2. Enter the Subnet Mask for the network that the router connects to.

3. Click Apply.

NOTICE. The LAN setup process changes the IP address of the Web User Interface. The
apply action causes the router to save your current configuration and then restart. After the
router restarts, you'll have to reapply to the Web User Interface using a new IP address.

DHCP

DHCP stands for Dynamic Host Configuration Protocol. This protocol dynamically assigns

IP addresses and related information to Local Area Network (LAN) nodes. For temporarily
connected network users, DHCP provides safe, reliable, and simple TCP/IP network
configuration.

The top DHCP menu screen lists DHCP server entries. To remove the entry…

1. Click the radio button beside the entry.

2. Click Delete.

You can also start or stop the DHCP server by clicking Start/Stop.

To create a new DHCP server entry, click Add.

Note: Before adding a new DHCP server entry, you must first stop the DHCP server.

The following screen appears:

Configure the following parameters:

•Interface. LAN port that the DHCP server will support.

•Starting IP Address. First IP address in a block of addresses. The DHCP server uses this

address in responding to a LAN port node’s DHCP request.

•End IP Address. Last IP address in a block of addresses. The DHCP server uses this
address in responding to a LAN port node’s DHCP request.

•Gateway. IP address of the Default Gateway or Router that the node will use.

•Netmask. Subnet Mask for the LAN that the node will be on.

•DNS. Domain Name Server. The DNS that the node will use. DNS is a server with a

database. The database translates a domain name into a corresponding IP address. For
example, “USR.com” resolves into IP address 231.222.320.4. Communications over the
LAN between the node and USR.com web site use this address.

•Lease Time. Number of days that the node can use a DHCP lease. Subsequently, you
must renew the lease with the DHCP server.

DHCP Relay

Suppose that a Dynamic Host Configuration Protocol (DHCP) server resides on a different
LAN than the node broadcasting for DHCP service. Then the DHCP broadcast request must
be forwarded across the router/WAN to a subnet where a DHCP server resides. The router
must relay the DHCP request. DHCP relay assures that the requesting node receives an IP
address that corresponds to the node’s subnet. The router must have a record of the DHCP
server’s IP address. With this address, the router can correctly direct the request to the
appropriate DHCP server.

After you input the IP address into the menu, start the relay agent by clicking Start.

U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide

DNS Relay

The DNS Relay function supports forwarding of DNS requests from a LAN node to a known
DNS server.

•Domain Name. Internet site address that the router is a group of (i.e. usr.com).

•Primary DNS Server. IP address of the Primary DNS that the router will use. Domain

Name Server (DNS) is a server with a database. This server translates a domain name into
the corresponding IP address. For example, USR.com resolves into IP address

231.222.320.4. Communications over the LAN between the node and web site USR.com
use this address.

•Secondary DNS Server. IP address of the Secondary DNS that the router will use.

•Gateway. IP address of the Default Gateway the Router is to use.

•DNS Relay. Enabling or Disabling router ability to convey a DNS request from a LAN node.

Routing Setup

A router forwards data packets between local area networks (LANs) or wide area networks
(WANs). Based on routing tables and routing protocols, routers read the network address in
each transmitted packet. Routers then decide where to send the packet. A router bases this
decision on the best route. The Routing Setup menu allows the user to configure how the
router forwards received IP packets.

RIP Information

Routing Information Protocol (RIP) is a routing protocol and is part of the TCP/IP suite. RIP
determines a route based on the smallest hop count between source and destination. RIP
determines the smallest hop count by communicating with other routers within the network.
Only use RIP if the target router also utilizes RIP.

•RIP Status=On/Off selection.

•Version= Version 1 (RIP1) or Version 2 (RIP2). Should match RIP versions used by other

routers in the network.

To save and install RIP data…

Spanning Tree-Bridging

Transparent bridges use the spanning tree algorithm to dynamically determine the best
source-to- destination path. This algorithm avoids bridge loops (multiple paths linking one
segment to another) within a network. The algorithm determines all redundant paths and
makes only one of them active. The spanning tree protocol (STP) is part of the IEEE 802.1d
standard.

Proxy Configuration

Proxy Services are specialized application programs. These programs accept users’
requests from LAN clients for Internet services like HTTP. On behalf of LAN clients, proxy
services also set up connections to WAN servers. A proxy server authenticates against the
user database (Access Control). The proxy server filters a request against the Access
Control List (ACL). Then the server forwards the request to actual services. Proxy Servers
are application specific. Each application needs its own proxy server.

To save and install proxy configuration data…

1. Click the radio button beside the HTTP proxy that you want to enable. (The illustration
above doesn’t show proxy radio buttons.)

2. Click Enable beside HTTP Proxy.

3. Click Authentication. Clicking this box authenticates the user during the HTTP
Proxy.

Should You Connect via Ethernet or USB?

The U.S. Robotics ADSL Ethernet/USB Router gives you the option to connect through a
USB or an Ethernet port. Selecting how to connect your router is a matter of preference.
Connection also depends on your available computer ports and the operating system that you
use. For example, you must use an Ethernet connection with these operating systems:
Windows 95, Windows NT 4.0, Macintosh and Linux.

U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide

Step 1. Connect Microfilters (If Necessary)

● If your package didn't include microfilters, and your ISP didn't provide any: Skip to Step

2 of these instructions.

● If your installation requires microfilters: Install one on each telephone device that shares

the same phone line as the ADSL signal. (Telephone devices include telephones,
answering machines, and fax machines.)

A microfilter is a small device that reduces interference between ADSL signals and telephone
signals. You only need a microfilter if the ADSL router and a telephone device share the
same phone line. If you don't use a microfilter, you may experience background noise on your
telephone during data transmission. Also, telephone calls may interrupt data transmissions.

Connect Microfilters to Telephone Devices

To install the microfilter, plug the phone into the microfilter, and then plug the microfilter into
the telephone wall jack. Do not install a microfilter on the cable that connects your router to
the telephone jack unless your microfilter has a connection for both the telephone and the
DSL device.

Terminal User Interface

Overview

The Terminal User Interface (TUI) is one of three router user interfaces. The other interfaces are
the Web User Interface (WUI) and Command Line Interface (CLI). Each interface allows you to
set up, modify, and view router configuration variables and operational data.

The Terminal User Interface is a system of hierarchical, character-based menus. See the
nearby overview for a graphic map of the interface.

Each menu presents options and prompts you for a response. Options occupy most of a menu
screen. The bottom of the screen provides information about expected responses…

● Mandatory vs. optional

● Allowable formats

● Operation success or failure

● Error messages

● Directions on what to do next

This document often refers to menu screens with path notation. For example, consider the
example in the following table…

U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide

IP addresses deliver packets of data across a network. These addresses differentiate the
source and destination IP address and keep them constant. When a router port detects a
packet, the router checks the routing table. The port attempts to match the network number of
the destination IP address with its routing table entry. If the port finds a match, it forwards the
packet to the destination network. With no match, the port forwards the packet to a router
defined as the default gateway.

Subnet masks split one network into a set of mini networks or subnets. Subnetting helps to
reduce traffic on each subnet. Subnetting also makes the network more manageable. Each
subnet functions as if it were an independent network.

U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide

● Configure Route. Enter 2 at the Routing Setup Menu. The Configure Route Menu

appears. From this menu, you can add new static routes. A router forwards data packets
between local area networks (LANs) or wide area networks (WANs). Based on routing
tables and routing protocols, routers read the network address in each transmitted frame.
Routers then decide how to send the frame. A router bases this decision on the best
route. The Configure Route Menu allows you to adjust how the router forwards received
IP packets.

To configure a route…

1. Enter a valid destination network ID. This is the network IP designation of the network
defined in the table.

2. Enter a valid destination subnet mask. This is the network subnet mask of the entry
defined in the table.

3. Enter a valid next hop ID. This is the IP address or gateway that the router uses to arrive
at the destination address.

4. After you complete your configuration, proceed to the Basic Menu and enter 8. The Save
& Reboot Menu appears. From this menu, save your changes and reboot the router.

this menu to turn RIP on or off. Also use the menu to define which RIP version to use. Routing
Information Protocol (RIP) is a routing protocol and is part of the TCP/IP suite. RIP plots a route
based on the smallest hop count between source and destination. RIP determines the smallest
hop count by communicating with other routers in the network. Only use RIP if the target router
also utilizes RIP.

DHCP Server

Enter 2 at the Advanced Menu. The DHCP Server Menu appears. DHCP stands for Dynamic
Host Configuration Protocol. This protocol dynamically assigns IP addresses and related
information to Local Area Network (LAN) nodes. For temporarily connected network users,
DHCP provides safe, reliable, and simple TCP/IP network configuration. DHCP confers these
benefits by preventing address conflicts and conserving IP address use. To conserve address
use, DHCP centralizes address allocation.

Starting IP Address First IP address provided on a LAN port node’s DHCP

request.

End IP Address Last IP address in the pool provided on a LAN port

node’s DHCP request.

Gateway IP address of the Default Gateway or Router that the

node will use.

Netmask Subnet Mask for the LAN that the node will be on.

DNS Domain Name Server. Actually, here we aren’t referring

to the DNS itself. Instead, we refer to the IP address of
the DNS that the node will use. DNS is a server with a
database. The database translates a domain name into a
corresponding IP address. For example, “USR.com”
resolves into IP address 231.222.320.04. Use this
address to communicate over the LAN between the node
and USR.com web site.

Lease Time Number of days that the node can use a DHCP lease.

Subsequently, you must renew the lease with the DHCP
server.

appears. This menu displays DHCP Relay information.

● Configure DHCP Relay. Enter 5 at the DHCP Server Menu. The DHCP Server Status

Menu appears. This menu allows you to configure DHCP relay functions. Suppose that a
Dynamic Host Configuration Protocol (DHCP) server resides on a different LAN than the
node broadcasting for DHCP service. Then the DHCP broadcast request must be
forwarded across the router/WAN to a subnet where a DHCP server resides. To assure
receipt of an IP address that corresponds to this subnet, the router relays DHCP. The
router must have a record of the DHCP server’s IP address. With this address, the router
can direct the request to the DHCP server’s appropriate input IP address.

To configure a DHCP relay, follow these steps…
