Hi,

I have a FreeBSD 4.1 machine which has been running as a natd router for the 
past 1.5 years. It currently has 2 network cards, one attached to my lan 
(192.168.*) and the other connected to my cable modem.

I now want to add another network card to the machine to server another lan 
(10.*). I want the FBSD machine to forward all traffic between the lans and 
provide NAT access through the cable modem to each. i.e.

               FreeBSD Machine
                  +-------+
     10.* ========|---+   |
                  |   +---|===== *. (outside world)
     192.168.* ===|---+   |
                  +-------+

Each of the subnets will machines set with their gateway as the FBSD machine 
anyway.

What ipfw rules do I need to do this?

Thanks
