Please someone help with my routing problem

[datadan_1]

I have rh6.2 and I can't ping from one ethernet to another.

10.1.31.0
10.10.12.0

I can ping from the .10.12 network to the linux box.
I can ping from the .1.31 network to the linux box.
But I can't ping from the .10.12 network to the .1.31 nework.

I don't have too much trouble manipulating the routing table, I just don't know what the routing table shoudl look like. What route do I need to put in that allows traffic to go back and forth between the subnets?


Please help!
Thanks.

Have you specified a default gateway address for the machines on each network? The IP would be that of respective NIC in the Linux gateway box. For example:
route add default gw 10.1.31.1

Check the Subnet Mask ... Networks on a different subnet cannot read each other ..,. try 255.0.0.0

oh and check to see ip IP fowarding is enabled .... Okam's Razor........

Ummm - are you sure about this? I've got three boxen running through a freesco router, all on 'different' class C networks (different subnets), and the only thing that gave me trouble was trying to browse the network(s) neighbourhood on Win98 machines.

Samba sorted that problem out for me, anyway &lt;g&gt;
