Dual-Ethernet Router Configuration
General Information on Dual Ethernet router
To configure the Dual-Ethernet router, access the router using the Command Line Interface (CLI). The CLI
can be accessed from a Telnet or a console session (using the console cable) connected to the router’s default
IP address of 192.169.254.254. You can also configure the router using the Web browser GUI. Refer to the
Dual-Ethernet Router Quick Start Guide
.
The Dual-Ethernet router has two interfaces:
ETH/0—refers to the router’s hub with four 10Base-T connectors
ETH/1—refers to the single 10Base-T connector
Bridging is enabled by default when the router boots up. IP and IPX routing are disabled.
The router’s default IP address is 192.168.254.254.
DHCP is enabled by default and the router’s DHCP server issues IP addresses to any PC request. The DHCP
default IP pool is 192.168.254. 2 through 192.168.254.20.
To connect to the router, use the router’s default IP address using a Telnet session, for example, and any
10Base-T port on the router.
Warning:
You cannot boot from the ETH/1 interface.
Configuring the Dual-Ethernet Router as a Bridge
This router is configured by default as a bridge and no configuration steps are needed. The user needs only
establish a connection to the remote location (to the Internet Service Provider, for example).
Bridging is enabled by default when the router boots up. IP and IPX routing are disabled.
Configuring the Dual-Ethernet Router for IP Routing
The
eth
commands are used to configure the Dual-Ethernet router for IP routing. Refer to the section
Dual-
Ethernet Router Commands (ETH), on page 172,
for usage and syntax information.
The last argument of each ETH command determines which interface is being configured (0 for ETH/0, 1 for
ETH/1).
Each interface (ETH/0 and ETH/1) must be set. A minimum of one route must be defined to have a working
configuration. This is generally a default route on the ETH/1 interface where all traffic otherwise specified is
automatically forwarded. This default route is: 0.0.0.0 255.255.255.255 1.
The Gateway address is the IP address supplied by your Internet Service Provider or Network Administrator.
You can customize your router by using the scripting feature, which loads batch files of preset configuration
commands into the router (refer to the
Batch File Command Execution, on page 228
section).
A Dual-Ethernet router sample configuration with IP Routing is provided in the
Sample Configuration 3:
Configuring a Dual-Ethernet Router for IP Routing, on page 68
section.
