Eth1 and eth0

Hello, Board:

I am using Fedora Core 2 in my computer, which is setup with two NICs: Eth1 NIC is connected to the LAN; and eth0 connected to the Internet. Also, eth1 NIC has as a gateway an interface of a router.

Both eth0 and eth1 are active. I can ping from one another interface and to any host on either side. The problem I have is that I cannot reach the other side of the router.

What can I do to be able to have my computer talk to both sides and across the router, when I know that the router will reply on the other side if I have eth0 (Internet) removed?

Thanks,

Jesus

I assume you network setup is something like this:


LAN1 PC1 ----|switch1---- eth1 <Your FC2> eth0------ switch2| ---- LAN2 PC1
LAN1 PC2 ----|switch1---- eth1 <Your FC2> eth0------ switch2|----- LAN2 PC2
LAN1 PC3 ----| switch1---- eth1 <Your FC2> eth0------ switch2|----- Gateway/Router ---- {Internet}


By default all PC on LAN1 should set their gateway to eth1 IP address then all PC from LAN1 should be able to reach LAN2

All PC from LAN2 should also set their gateway to eth0 IP address to allow them to access LAN1

Do a command - route on you FC2 and you will see the routing table.
