Is your FreeBSD box hooked directly to the frame-relay or point to point
connection to your ISP, or do you have a router and the FreeBSD box is
hooked to the router over ethernet?

It could be that your router (the one hooked to the upstream provider) has
the entire class c routed to it's ethernet interface, in which you can
only put nodes on it.  If you set up that router to do private IP on a
crossover cable to your freebsd box (multihomed freebsd), then on do
gateway_enable in /etc/rc.conf, and from the other router hooked to your
ISP you set a static route to the private ip address of your freebsd
box.  Then, on the other Freebsd nic, set an IP address and netmask for
the NIC, then that will work.

Have I thoroughly confused you yet?

If your freebsd box is hooked directly to your ISP, then you just need to
set your IP address and netmask for your NIC on the ethernet
network.  255.255.255.0 will be your netmask.  That's 24 bits for network
and 8 bits for host.

Sincerely,

Rick Duvall
