Re: routes question



try to give gateway at /etc/sysconfig/network

GATEWAY=XX.XX.XX.XX
remove it from both the nic.

then restrt the network services.

#service network restart.

then check route -n

Destination     Gateway         Genmask         Flags Metric Ref    Use

Some thing like last line should be apear.

Hope this will help you.

I've setup a gateway/router for a small internal network that we are
using to disinfect virus ridden windows machines. eth0 serves the ip's
to the internal network (192.168.1.1) and eth1 is connected to the
internet (130.111.68.110).

This works very well, except when I start the machine with the eth0
network cable unplugged and then plug it back in after the machine has
started. When this happens, people are still able to get an ip but are
not able to get out on the internet. If I go on the server and try to
ping something, it doesn't work, it's trying to use eth0 to ping and
is getting a host unreachable. A restart with the cable plugged in
seems to fix it.

I'm thinking this has to do with setting routes. Though I'm not sure
what routes are appropriate to set. Should eth0's route be
130.111.68.1? Does this sound like a route problem?

Here is the output of the routes command:
