2 NICs 2 networks 2 gateways

We have a redhat machine sat on two networks, each network having its own gateway. We want the machine to be able to see both networks and connect to machines through the gateways. We do not want the machine to allow talk between the two networks however.

I set up the two gateways in /etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-eth1, and commented out the default gateway in /etc/sysconfig/network.

# netstat -rn

Kernel IP routing table
Destination____Gateway________Genmask Flags MSS Window irtt Iface 0 0 0 eth1 0 0 0 eth0 0 0 0 lo 0 0 0 eth1 0 0 0 eth0 0 0 0 eth1 0 0 0 eth0

This allows me to ping IPs on the network, includign those that can only be reached through the gateway However, despite being able to ping the gateway I cannot ping anything through it.

Does anyone know what is going on? This is very confusing and any help would be greatly appreciated!

Many thanks,

You should try adding a route for 10.172.x.x informing your computer how you want it to try to get there using the 'route' command:

route add -net netmask eth1
