Yes, the FreeBSD machine has been acting as a router/gateway/firewall
for the wired network for quite some time. I did look at the handbook,
that's usually my first stop.

Also, made one small error in my initial post.  The wireless router has 
IP 192.168.1.1 and the server's 'wireless' interface is 192.168.1.2 
(going to switch these as soon as I get access to the wireless router 
settings).

I've tried setting static routes between various interfaces on the 
FreeBSD machine, it hasn't worked, but I may be doing it wrong. I 
thought routed should take care of this dynamically, but I'm a bit 
unsure about that.
