Netopia R910 manual System configuration screens, User’s Reference Guide

8-44 User’s Reference Guide

■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.

■Local WAN IP Address allows you to manually configure an IP address for use on the Ethernet WAN port. The value 0.0.0.0 indicates that the device will act as a DHCP client on the Ethernet WAN port and attempt to acquire an address from a DHCP server. By default, the router acts as a DHCP client on the Ethernet WAN port.

■Local WAN IP Mask 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 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 13-126.

■

Remove Filter Set allows you to remove a previously associated filter set.

The Receive RIP pop-up controls the reception and transmission of Routing Information Protocol (RIP) packets on the Ethernet WAN port. The default is Both. The Transmit RIP pop-up 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 Netopia R910 needs to recognize. Set to “Both” (the default) the Netopia R910 will accept information from either RIP v1 or v2 routers. Alternatively, select Receive RIP and select v1 or v2 from the popup menu. With Receive RIP set to “v1,” the Netopia R910’s Ethernet port will accept routing information provided by RIP packets from other routers that use the same subnet mask. Set to “v2,” the Netopia R910 will accept routing information provided by RIP packets from other routers that use different subnet masks.

If you want the Netopia R910 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 Netopia R910 will generate RIP packets only to other RIP v1 routers. With Transmit RIP v2 (broadcast) selected, the Netopia R910 will generate RIP packets to all other hosts on the network. With Transmit RIP v2 (multicast) selected, the Netopia R910 will generate RIP packets only to other routers capable of recognizing RIP v2 packets.

System configuration screens

You can connect to the Netopia R910’s system configuration screens in either of two ways:

■By using Telnet with the Router’s Ethernet port IP address

■Through the console port, using a local terminal (see “Connecting a console cable to your router” on page 6-33)

You can also retrieve the Netopia R910’s configuration information and remotely set its parameters using the Simple Network Management Protocol (see “SNMP” on page 12-118).

Open a Telnet connection to the router’s IP address; for example, “192.168.1.1.”
