How to control ethxx gateway

Vernon Brown_4 — Sun, 11 Sep 2005 17:33:42 GMT

I have a workstation with eth0 and eth1. Eth0 connects to a cable modem with internet access. Eth1 connects to a LAN router which has DSL internet access. I want to control which eth card is my gateway to internet access while keeping both eth cards active.

You need to set the default gateway. It should be in networks file in /etc/inet directory.

Vernon,

Add a statement to the config file.

/etc/sysconfig/network-scripts/ifcfg-eth0 or eth1

You really can't have two DEFAULT gateways, but but there is nothing that says you can't have gateway statements.

GATEWAY=192.168.0.15

Or whatever.

if you are running redhat then edit /etc/sysconfig/network file and set GATEWAY= to your default gateway IP address.

/etc/sysconfig/static-routes -- defines the static routes that are non interface-specific.

/etc/sysconfig/network-scripts/route-eth? -- defines the interface specific static routes. (I think started with RHL9/RHEL3; before that all static routes were in /etc/sysconfig/static-routes)
