Hi. I want to get some games and other things working on machines inside my Linux NAT server.
eg for Close Combat, I need ports 47624 and 2300-2400 on both TCP and UDP redirected so from the outside they look like they're going to/from my Linux box, but everything gets redirected in both directions to my PC. I also want to redirect different ranges of ports to different machines on my internal network. I *need* to be able to play Total Annihilation from my Mac! I can't work out how to do this. All the instructions I can find tell me to use ipfwadm, but Debian doesn't seem to offer it (not listed in debian packages, for example). I presume ipchains can do this, but I don't seem to have an ipchains man page (how can I reinstall the man page, btw?) and I could never make that work anyway. I'd love to understand the general theory of how to redirect particular ports for particular protocols to particular machines. ipchains? ipautofw? ipportfw? TIA
