add a static route on the Nat machine.

route add 192.168.66.0 192.168.66.1/24

>Can this be done with routing or do I have to use ipfw to forward between both networks? I would prefer just to run the nat & ipfw instance on the DSL interface and run pure routing between the lan interface & the interface which connects to the frame-relay network..
