here is some photo.Īs you can see from sc, everything is RED lag, and i get that error msg if i try to join any games. like you said, i should be able to join games without any configtion to router, but it appears other wise. anyways i disable the special app, and just left virtual, but no dice either. but i also play sc on laptop late at nite. basiclly i config my main comp to have DMZ while my laptop is safe under router firewall. its just annoying that i have to reconfig router to different DMZ ip just to play. i COULD be playing sc on either one of the computer that connects to this router, but not at the same time. i understand what u saying about two comp at same time, but let me rephase myself. Hey, thanks for your help, but its still not working. Also, if you have the firewall enabled on an SMC router, you'll need to allow TCP port 6112 in through the firewall.ĭunno what you're messing with port 5190 for. The special application settings may be interfering, since the only use for that is with applications that automatically need to open certain ports. So when the return traffic comes back, it knows that the traffic from server A is meant for computer A, and traffic from server B is meant for computer B. The router uses certain information in the packets and in the NAT table so that it knows that even though you're both using the same port, the traffic is going to different remote IP addresses. If you both connect to different servers, then depending on the router, it may be able to handle it just fine. Server A responds to one of you, how does the router know which one of you the response is meant for? Computers A and B both connect to server A, on the same port. The router's mapping of NAT translations gets confused.

If you both try to connect to the same server, the router doesn't know how to handle the traffic because two different internal IPs are connecting to the same remote server IP, on the same port. The problem is that your router is using a single external IP address to connect. When you connect to a game, your computer uses UDP port 6112 to connect to the server. Your machine connects to on TCP port 6112 to make the initial connection. You shouldn't need any port forwarding just to connect to a server online. The TCP connection is only used for chat over, and doesn't need to be forwarded because it's only made by your machine to the b.net server once and then kept open. Starcraft needs UDP port 6112 forwarded both in and out, not TCP, and is only needed if you are the one hosting the game.
