    I have a box running 4.8 that is my gateway. I've used this box with 2
    NICs, one to my internal LAN and one to the Internet, and it works well.
    Now I've added a third NIC and attached a Netgear wireless/ethernet bridge
    (ME101) which I want to use to connect to a wireless access point (my
    neighbor's). Here's a diagram:

            Internet
                |
            Public IP
                |
          ADSL Modem/Router
           192.168.10.1
                |
               dc0
           192.168.10.2
                |
            FBSD 4.8 ------- rl0
                | |
               dc1 192.168.0.2
           192.168.1.2 |
                | Wireless Bridge
           Internal LAN

    I want packets addressed to the 0 subnet to be passed to the rl0 interface
    and the 1 subnet to the dc1 interface. All other packets should be passed
    to dc0.

    I've read the handbook on routing and I think my configuration is correct,
    yet I can't reach any hosts on the 0 subnet. Specifically I should be able
    to connect to the web configuration interface on the bridge but can not. I
    can't even ping the bridge from the gateway machine. I can ping the rl0
    interface from machines on the 1 subnet. Here's my routing table:

    Routing tables

    Internet:
    Destination Gateway Flags Refs Use Netif Expire
    default router UGSc 6 660 dc1
    localhost localhost UH 1 10 lo0
    192.168.0 link#1 UC 2 0 rl0
    192.168.0.2 00:05:5d:d0:ba:67 UHLW 0 8 lo0
    192.168.0.200 link#1 UHLW 0 1 rl0
    192.168.1 link#2 UC 4 0 dc0
    bigdaddy 00:0c:6e:32:73:b1 UHLW 2 1195 dc0 1114
    blacklamb 00:e0:18:c4:f4:5e UHLW 0 39 dc0 1131
    192.168.1.11 00:a0:24:95:d7:d8 UHLW 0 97 dc0 209
    192.168.1.255 ff:ff:ff:ff:ff:ff UHLWb 1 39 dc0
    192.168.10 link#3 UC 1 0 dc1
    router 00:c0:49:27:b2:0b UHLW 7 600 dc1 765

    Based on my understanding of the handbook, this should work. Can anyone
    confirm this for me? Is there something I'm missing?

    Thanks,

    Drew
