I've got a version of that set up at home. You can definatly do it with choparp. Assuming the addresses you want to proxy are in a block which could theoreticaly be subnetted (i.e. properly aligned and sized) then you can do this fairly easily. I've got a setup where I've got 16 IPs within a /24 subnet from my ISP. I simply configured my box with the outside interface set up like normal on the /24 net and the inside interface on the /28 net consisting of my IP addresses. I then use choparp to proxy the entire /28 subnet on the outside interface. With forwarding enabled my other hosts think they are on a /28 subnet and everything just works. > Please see the thread "arp proxy" in freebsd-questions, where Christ J. > Clark does his best to help me. His "no docs on a sysctl switch! > *SHOCK*" gave me the idea of creating the PR btw.. I don't read -questions. My pain tolerance isn't that high. ;-) I did dig your message up on Geo Crawler and it looks like your situation is virtualy identical to mine so choparp should do it. If you're addresses aren't aligned, then you're may have to do some weird things, but it should be possiable to make it work. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
