Hi all, I'm fairly new to linux and ran across a problem that I'm not sure how to fix. I'm running a Linux box (Mandrake 7.0), which is set up as a router for my other winblows comps. I am trying to use a program called battlecom(on windows comp), which has not worked since I started using my linux box as a router. I found the config below on the website of battlecom, but I wasnt sure where I'm supposed to enter these lines. Do they go into the etc/rc.d/rc.local file?? Any help is highly appreciated. Thanks Marc Step 1: You need to have root or su access. Step 2: Find the ipmasqadm rpm for ipchains or the ipautofw rpm if you're using ipfwadm and install the RPM (if not already installed... can be found at rpmfind.net) Step 3: For IP Chains use this command set: ipmasqadm autofw -A -v -r udp 2300 2400 -h www.xxx.yyy.zzz ipmasqadm autofw -A -v -r tcp 2300 2400 -h www.xxx.yyy.zzz ipmasqadm autofw -A -v -r tcp 47624 47624 -h www.xxx.yyy.zzz ipmasqadm autofw -A -v -r udp 47624 47624 -h www.xxx.yyy.zzz ipmasqadm autofw -A -v -r udp 28800 28900 -h www.xxx.yyy.zzz For ipfwadm: ipautofw -A -v -r udp 2300 2400 -h www.xxx.yyy.zzz ipautofw -A -v -r tcp 2300 2400 -h www.xxx.yyy.zzz ipautofw -A -v -r tcp 47624 47624 -h www.xxx.yyy.zzz ipautofw -A -v -r udp 47624 47624 -h www.xxx.yyy.zzz ipautofw -A -v -r udp 28800 28900 -h www.xxx.yyy.zzz You should replace www.xxx.yyy.zzz with the IP Address of the PC behind the masquerade that will be running the BattleCom Client.
