    I guess I didn't make it clear enough, let me try again.

    I'm attempting to create a static route for my FreeBSD host so that
    *all* local traffic is routed across the gateway firewall, rather than
    being delivered on the local network segment, as is the default with
    LANs. If you view the routing table (below) again, you'll notice that
    traffic from the FreeBSD box (192.168.0.53) to another box on the same
    subnet (192.168.0.42) is still being delivered locally, rather than
    being routed through the gateway (192.168.0.1). This is *after* I've
    added a static route for 192.168.0.0/24 to use 192.168.0.1.

    Destination Gateway Flags Refs Use Netif Expire
    default 192.168.0.1 UGSc 2 0 fxp0
    127.0.0.1 127.0.0.1 UH 1 0 lo0
    192.168.0 link#1 UC 3 0 fxp0
    192.168.0.1 00:a0:cc:e2:7e:f4 UHLW 3 808 fxp0 596
    192.168.0.42 00:05:5d:a6:df:e3 UHLW 1 63 fxp0 992
    192.168.0.53 127.0.0.1 UGHS 0 0 lo0

    There are no routers inbetween. Just a host on a LAN behind a firewall
    (which routes between the LAN and the internet, of course).
