The Yes. > way I prefer it, is to route between the nets, but stay with a single NIC. You may *think* you prefer it, but if you do it that way you'll find that 1 NIC per network is best. > Is it enough to simply bind an IP address of the old net to the routing > box's NIC, and it will then automatically forward packets? I know this may > be a silly question, but I am little confused about it. I hope someone may > give me a hint or two :) You can put IP addresses 194.19.1.1 and 194.19.2.1 onto a single NIC and have two logical networks on the one cable, but it would be better to have 194.19.1 machines on one physical network and 194.19.2 machines on another. Don't forget to enable gateway="YES" in rc.conf. Dnny
