Networking issue with Starcraft

[octopus41092]

I can host and everything but the problem is when me and one other person on my network behind the same router joins the game it lags. We can both join different games and play just fine. I have the ports 6112-6119 open. From what I've read it has problems sending packets to the right place.

One system is running Windows XP Professional the other is running Windows Vista Business 64-bit. The other thing is that there's a third computer on the network that needs to be able to host for Warcraft III so that has to work too. With port forwarding it makes it so that computer can't host.

Does anyone know how to fix this or if there's a program like pickuplistchecker but for Starcraft?

tell me you have a switch and not a hub

I have a router, D-Link DIR-655.

I don't think this will solve your Starcraft lag problem, but for Warcraft III, you only have to forward the ports used by listchecker (and the one in WC3 settings) to the computer that hosts. For example, I use listchecker with the default settings, which is 6112 for LC and 6113 for Warcraft. So I only forward 6112-6113 to my computer. Just select some other port for Starcraft (like 6114 or whatever, forward that port to your Starcraft computer, and host with it.

Starcraft unfortunately doesn't have LC Host. Also, the port forwarding is not the problem. I have the ports OPEN so that traffic can come in. With forwarding I can only forward to one computer and that doesn't work for me. Is there some way that I can get all information from those ports sent to multiple locations instead of it trying to figure out where it goes? I think the issue with Starcraft is that it is sending the wrong information to the wrong ports or is takign too long to figure it out. Like I said before, I get intermittent lag in the game with two people behind my network in the same game.

Here is the solution Octopus. This is a known problem with Starcraft as it was never designed to work with more than one machine with a router. For some reason they never made a patch to fix it but a quick search brought me the information i used last time and it worked great:

on any client machine (ie not the router/server) go to start->run->regedit and find this key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Battle.net\Configuration]
and in there make a new DWORD key, name it "Game Data Port" and its value should be in decimal 6112 or 6113 and so on, a different value for each machine, then you have to set up the router to make those ports work on those IPs

So basically it is a port forwarding issue but you have to define it in the router and also in those registry keys.
