I'm trying to setup 2 wireless networks being served by one server with 2
NICs. I need 2 wireless networks due to the number of subscibers. The
server will provide dhcp, dns and a proxy. The proxy is required by my
satellite provider. DHCP and DNS both work correctly, but the proxy is
only able to connect to the server @ 10.10.11.50 via eth0. eth1 will not
connect. I am able to route to eth0 but not to eth1. I have tried adding
the following to /etc/sysconfig:

network-scripts/route-eth0 containing 10.10.11.50 via 192.168.1.1
network-scripts/route-eth1 containing 10.10.11.50 via 192.168.100.1

The only route that shows up is the route via 192.168.1.1.

I have tried adding static routes, but then niether interface connected.

Is there any way to accomplish what I am trying to do?

Is your FC2 server also serving as a router to connect your 2 wireless LANs together?


I don't think you really need to be able to connect to 10.10.11.50 via both interfaces. If the clients on network 192.168.1.0/24 are assigned a gateway of 192.168.1.20 (your eth0) and the clients on network 192.168.100.0/24 are assigned a gateway of 192.168.100.20 (your eth1), then they should all send packets for any off-net addresses such as 10.10.11.50 to you. You only then need a single route to that IP in order to be able to forward those packets to the right destination.

So you should be able to get rid of network-scripts/route-eth1 and the clients on that network should still be able to send packets to 10.10.11.50, by forwarding the packets to you (who has IP forwarding turned on), and you forward the packet via eth0 to 10.10.11.50.
