    It's sounds like IP forwarding isn't working. Take down the interface
    that uses 10.1.1.1 and then try to ping the firewall. What happens?

    What is the output when you run "cat /proc/sys/net/ipv4/ip_forward" ?
    If you get a zero, execute "echo 1 >/proc/sys/net/ipv4/ip_forward" bring
    up the 10.1.1.1 interface and try things then. Let us know what happens.
