I have an interesting problem: I'm moved into university and people can't join custom games I create in warcraft 3. However, people CAN join games I create in starcraft. What would cause this? How do I fix it?
 
Physics news on Phys.org
You'll need to try forwarding some of the ports required by Warcraft 3. I believe they are:

TCP and UDP: 6112-6119
TCP: 116 and 118

You'll need to poke holes in your firewall accordingly as well.
 
Hmm, not sure about that, but in my case i can play LAN games with my friends as long as they are in the same college. I can't play with them even they are in the same university network but different colleges.

Well, for portforwarding, u could try www.portforward.com .
 
How do I forward the port? Keep in mind I'm at university and they're not going to let me touch any of their stuff.

I've used Putty to forward a port for mail before, but only because step by step instructions were given.
 
You could read this article: http://puremhz.com:8080/showthread.php?t=3424 .

It talks about how to set up an SSH tunnel and send any and all traffic through the tunnel to a "server" you've set up elsewhere.

I guess if this doesn't help you, you could google along similar lines and find a solution. btw, starcraft is a really great game.

Hope it helps.

First thing you need to do is forward your port on your modem. not all modems are compatible with this. http://www.portforward.com/english/applications/port_forwarding/Warcraft_III/Warcraft_IIIindex.htm select your modem and follow the steps from this link. you will also need a LAN emulator to play with people from different colleges or any friends. Try Hamachi http://hamachi.en.softonic.com/

Set up your LAN with hamachi and host games with anyone on the server

Hope this helps :D
