Yeah, but if you're just passing packets to and from three subnets, then you can get away with less than a handful of rules to cover it. > > There is an easier way to forward packets from each network.

Totally, but if you have a firewall in place, you're still going to need to allow the traffic to pass through in either direction. > >> >> I suspect the easiest way may be to have one NIC per subnet in the fbsd >> router, and use natd. > More than one nic is not required, but if you have the slots available, it > can save some increadible headaches.
