My friend's having a problem with using a router and, although I'm sure I've seen it answered before, I can't remember what the answer was :-)

He and his friend want to play war3, but they're both on the same router. When he creates a game, only the person on the other computer can join it.

Is there some way to be able to host on one computer, and play both from battle.net and the other computer on the network?

Thanks!

Yes. Forward all packets from port # (6112-6119) (TCP) to his internal IP. On my old router it was under port forwarding.

Ok, that's what I thought, but he doesn't know how to do that, and I don't have physical access to his computer. Ohwell, I'll tell him that.

Thanks!

I found this on a website:
---------
To host from behind a router, you must access the setup software inside your router and find the "Forwarding" section (usually under "Advanced" settings). Port forwarding is used to set up public services on your network. When users from the Internet make certain requests on your router, they will be redirected to the specified IP.

After identifying the IP address of the computer you are hosting on, set "Service Port Range" to 6112-6119, then in the Protocol section, pick "Both TCP and UDP".

war3 needs udp?

I've used just TCP and it's worked ok - I'm not sure what uses the UDP on it.

That's because when you send outgoing UDP you can receive incoming UDP. It's hard to explain, but it works.

I never even checked, that's actually from a site about how to host a dedicated server for Ghost Recon, which apparently needs both :)

Ghost Recon supposedly uses tcp for the game and udp to measure latency.
