Multiplayer with 2 computers on 1 IP

[UThomas]

Which games support this and how do they do it? I want to have to computers playing the same game behind my router. I know on Half Life you had to change the command prompt to use a different port for the second computer. I'm specifically wondering about Quake 3 and Return to Castle Wolfenstein. Also, how about Unreal Tournament?

I believe you have to set up a DMZ host in order for 2 computers to play a game behind a router. It's usually somewhere in the router configuration page. Which router are you using? Hope this helps.

I've never looked into how, but I've seen(on several occasions) 2 kids from the same ip playing on a Tactical Ops server(UT mod), so I'd imagine UT can do it.

I know Unreal works. Pretty sure Quake3 works, although it's been a long time since I tried. I should try RtCW, because I'm sure I'll be wanting to play when friends/family come over but lately I've just been too preoccupied with trying to finish it. I assume it'll work. Any MS Gamezone games will NOT work behind a router unless you forward the specific ports the game uses to the specific PC you want to play on. This means no way two machines can play at the same time.

quake3 and all its mods work
halflife and all its mods work
RTCW works
I've played all three with multiple machines behind a router with no port settings

Battle.NET (starcraft, diablo, etc) will not work, since bnet requires everyone use UDP 6112, and two computers cant use the same port and IP

My roommate and I have had no probs playing behind my Linksys router...except for when CS started noticing the "Key Already in Use" crap, then he had to buy his own verison :frown:

What router do you have?

You should have to do nothing.


The IP is used just to connect the two networks. The MAC-Address of the network cards (NIC) will be used for addressing to specific machines.

This is how multiple machines can share one "IP"
