Embedded Software Version 8.7.4. Telnet-based management provides access to a wide variety of features that
the Router supports. You can customize these features for your individual setup. This chapter describes how to
access the Telnet-based management screens. This section covers the following topics:
•
“Motorola Netopia® Telnet Menus” on page 1-2
•
“Motorola Netopia® Models” on page 1-3
•
“Connecting through a Telnet Session” on page 1-4
•
“Navigating through the Telnet Screens” on page 1-5

Telnet Menus
Telnet-based management screens contain the main entry points to Motorola Netopia® Embedded Software
Version 8.7.4 configuration and monitoring features. The entry points are displayed in the Main Menu shown
below:
•
The Easy Setup menus display and permit changing the values contained in the default connection profile.
You can use Easy Setup to initially configure the Router directly through a Telnet session.
Easy Setup menus contain up to five descendant screens for viewing or altering these values. The number
of screens depends on whether you have optional features installed.
The Quickstart Guide describes the Easy Setup menus to get you up and running quickly.

Connecting through a Telnet Session
Features of Motorola Netopia® Embedded Software Version 8.7.4 can be configured through the Telnet
screens.
Before you can access the console screens through Telnet, you must have:
•
A network connection locally to the Router or IP access to the Router.
•
Telnet software installed on the computer you will use to configure the Router
Configuring Telnet software
If you are configuring your device using a Telnet session, your computer must be running a Telnet software
program.
•
If you connect a PC with Microsoft Windows, you can use a Windows Telnet application or run Telnet from
the Start menu.
•If you connect a Macintosh computer, Mac OS X users can use the Terminal application that comes with
Mac OS X in the Utilities folder.

Introduction 1-5

2-2 Administrator’s Handbook
•Address Translation Enabled allows you to specify whether or not the router performs Network Address
Translation (NAT) on the Ethernet WAN port. NAT is enabled by default.
•Obtain WAN address via DHCP allows you to toggle WAN DHCP Off and On. DHCP is On by default. so that
if you do not change the setting, the Router will acquire its WAN IP address automatically. By default, the
router acts as a DHCP client on the Ethernet WAN port and and attempts to acquire an address from a
DHCP server.
•The Local WAN IP Address field allows you to manually configure an IP address for use on the Ethernet
WAN port. This field only becomes visible if you toggle Obtain WAN address via DHCP to Off.
•The Local WAN IP Mask field becomes visible if you specify a Local WAN IP Address. This allows you to
manually configure an IP subnet mask for use on the Ethernet WAN port. This item is visible only if you
have configured a non-zero Ethernet IP Address; otherwise, the router obtains a subnet mask via DHCP.
•The NAT Map List and NAT Server List options are set to the defaults, Easy-PAT List and Easy-Servers.
These provide standard NAT mappings. For more advanced NAT configurations, see “Multi-NAT” on
page 4-1.
•NAT Options allows you to specify IP Passthrough, allowing a single PC on the LAN to have the router’s
public address assigned to it. See “IP Passthrough” on page 4-27.
•If you set Stateful Inspection Enabled to Yes , you can enable a security feature for computers on your LAN
when NAT is disabled. See “Stateful Inspection” on page 3-3.
•The Filter Set pop-up allows you to associate an IP filter set with the Ethernet WAN port. See “About Filters
and Filter Sets” on page 10-20.
•Remove Filter Set allows you to remove a previously associated filter set.
•The WAN Ethernet Speed Setting is configurable via a pop-up menu. Options are:
•Auto-Negotiation (the default)

This may be useful in mixed networks, where multiple routers have different ethernet speed capability. If
you want to maintain a single speed setting for compatibility with multiple routers on your LAN, you can
select a speed/duplex combination that all of your routers can match.
•The Wan Ethernet MAC Address is the hardware address of the Motorola Netopia®device. Some service
providers require a specific MAC address as part of their authentication process. In such a case, you can
enter the MAC address that your service provider requires. If your service provider doesn’t use this
method, you don’t need to change this field.
•The DHCP Client Mode setting depends on the type of access concentrator equipment your service
provider uses. Most use Standards-Based. Alternatively, your provider may instruct you to select Copper
Mountain Specific.
•The RIP Options selection displays the WAN Ethernet RIP Parameters screen.
•The Receive RIP pop-up menu controls the reception and transmission of Routing Information Protocol
(RIP) packets on the Ethernet WAN port. The default is Both.
WAN Ethernet RIP Parameters
+----------------+
+----------------+
Receive RIP: | Off |
| v1 |
| v2 |
| Both v1 and v2 |
| v2 MD5 Authentication
+----------------+

2-4 Administrator’s Handbook
The Transmit RIP pop-up menu is hidden if NAT is enabled.
Routing Information Protocol (RIP) is needed if there are IP routers on other segments of your Ethernet
network that the Motorola Netopia®Router needs to recognize. Set to “Both” (the default) Motorola
Netopia® Embedded Software Version 8.7.4 will accept information from either RIP v1 or v2 routers.
Alternatively, select Receive RIP and select v1, v2, or v2 MD5 Authentication from the popup menu. With
Receive RIP set to “v1,” the Motorola Netopia®Router’s Ethernet port will accept routing information
provided by RIP packets from other routers that use the same subnet mask. Set to “v2,” the Motorola
Netopia® Embedded Software Version 8.7.4 will accept routing information provided by RIP packets from
other routers that use different subnet masks.
For more information on v2 MD5 Authentication, see “RIP Options” on page 7-9.
If you want the Motorola Netopia®Router to advertise its routing table to other routers via RIP, select
Transmit RIP and select v1, v2 (broadcast), or v2 (multicast) from the popup menu. With Transmit RIP v1
selected, the Motorola Netopia® Embedded Software Version 8.7.4 will generate RIP packets only to other
RIP v1 routers. With Transmit RIP v2 (broadcast) selected, the Motorola Netopia® Embedded Software
Version 8.7.4 will generate RIP packets to all other hosts on the network. With Transmit RIP v2 (multicast)
selected, the Motorola Netopia® Embedded Software Version 8.7.4 will generate RIP packets only to other
routers capable of recognizing RIP v2 packets.
ADSL Line Configuration screen
The ADSL Line Configuration screen is shown below:
1. Select Circuit Type and from the pop-up menu choose the type of circuit to which you will be connecting:
Multimode, T1.413, G.dmt, or G.lite.
2. Select Trellis Coding Enabled. Toggle it to On (the default) or Off.
3. Select Signaling Mode and choose Echo Cancellation or FDM (the default).
4. If you selected Multimode Circuit Type, the Fast Retrain Enabled field appears. Toggle it to On (the default)
or Off.
