help setting up port forwarding

[onearmedscissor]

ok, i've read everything i could find about port forwarding and i still can't get it to work. i'm at my friend's house right now and i did the same thing i did for my router (which works fine), plus a ton of other things that different sites recommended. the only difference is his router is a wireless and mine isn't. his model is linksys wrt54g. it's wireless, but he has a cord directly connected to it. his internet is provided by a satellite dish, if that matters.

i've tried to get forwarding to work for two applications: warcraft iii and azureus bittorrent client. i went to the router settings, and game and applications tab, then i typed in the port for warcraft on both sides (6112) and selected both for the udp/tcp option. i typed in wc3 under application name. then i typed in 101 (my internal ip). doing this is supposed to let me host games on warcraft, but it didn't help. i also did the same thing with different ports for azureus and it gives me a nat error when i test it and shows a yellow status signal.

i've tried unplugging the router and the cables and replugging them in. my internal ip changed from 100 to 101 and i tested forwarding with both, but neither worked. i changed my azureus port twice and none of them worked either. and i tried ports 6112 and 6113 for warcraft iii but no luck. i also tried enabling and disabling my software firewall (kerio), but it didn't change anything. i even tried dmz host but that didn't work either. i had dmz host, kerio disabled, and ports forwarded all at once even, but it STILL didn't work. i have windows xp and i've disabled the xp firewall. i have no idea how to fix this, so can anyone please help? thank you very much.

edit: and i tried restarting the computer and unplugging the power from the router.

Remove the computer from the router so it's directly connected, and try forwarding all those ports on your software firewall. Is he getting a real ip address from his satellite provider, i.e. routable and pingable? Some sattelite providers automatically hand out private ip's now, which puts you in a double NAT scenario if you're using a router and that will make things a little more complicated.

thanks, but how do i test if his ip is routable? and by forwarding the ports on my software firewall, do you just mean to let whatever program i'm using access them? and what's a double nat scenario mean? sorry for the dumb questions.

Not dumb questions at all. In his router, look at the connection status page, and see what the wan ip is, it should not be a private ip address, 10.0.0.0 - 10.255.255.255, 172.16.0.0 - 172.31.255.255, 192.168.0.0 - 192.168.255.255. NAT (network address translation) is what your router does, it takes a real ip from your provider, and distributes private ip addresses to all connected computers, i.e. the reason your ip address from the router is 192.168.xxx.xxx. If your provider is giving you a private ip, then your router is taking that and giving you a different private ip on a different subnet, which would constitute a double NAT scenario. Hooking your computer directly to the sattelite modem, and creatiing rules for your software firewall for the games you listed is a good test to check. Create rules in your software firewall allowing warcraft or whatever game to have access to the ports it needs. If all is well, then the games should play fine and you know you need to research port forwarding on the linksys. Their site has manuals for all their products as well as a knowledge base.

there's a white wire that comes from the wall and is connected to a bridge, on the side with "p data out," then a red wire coming out the other side with "data in" on it. the red wire connects to the internet slot on the router, and a blue wire is connected to the "1" slot that directly connects to the computer. the internet works fine with this setup, but when i took the red wire out of the router and plugged it directly in the computer, where the blue one used to be, the internet didn't work at all. then i plugged the white wire directly into the computer but that didn't help either.

and on the router page, under status > router > internet > configuration type, it says under ip address "10.10.17.**." i'm not sure if that's the one you mean since i couldn't find one for wan anywhere. the ip address i get on whatsmyip.org is completely different. any more help would be greatly appreciated. thanks again!
