A router just receives IP packets and decides where the next place to send them should be. You probably are not just routing. Does each of the eight machines have a globally valid IP address that you some how get from @Home? If they do, you may be doing routing (but I would more likely expect bridging). If they are not, you are doing network address translation (NAT). NAT seems to be what you are incorrectly calling proxying (but you seem to realize this). IPFilter, ipf(8), and IPFW, ipfw(8), do not do NAT themselves, but each has closely associated software that does the trick, ipnat(8) and natd(8), respectively. A simple NAT setup is quite easy to do. Have a look at the various documentation and feel free to come back with more specific questions. -- Crist J.
