    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.
