I am a network technician and I know how to solve this problem. the triggering range is 3073-3075 forward port 3074.the triggering range is 87-89 forward port 88.the triggering range is 79-81 forward port 80.the triggering range is 52-54 forward port 53.The reason both 360s wont work, or work a short time, is that the router handling the packets doesn't know which 360 to forward them to so comes the problem with it.īy enabling the DMZ you are basically putting one 360 outside your nat network and the router can send the packets to each 360 without any problem.īy the way, lag shouldnt be any problem if you have a decent internet connection. Save your settings and you should be good to go. It will ask for an IP Address at which just enter one of the Xbox 360. You need to find out the ip address of the 360s, you actually only need one but it's nice to know both just in case.Īt this point you need to enable the DMZ feature in the router. You are going to want to enable the UPnP setting and just to help out, open the port numbers for the xbox, they can be found online with google. When you have the router get into the interface of it, ie log on with the ip address (192.168.1.1- might vary but should be mentioned in the manuel.) Get a good router, perferably linksys since I did this with one. And sorry if someone else has posted this elsewhere and this is a repost.įirst. This is to anyone who wants to connect two Xbox 360s on one network and have them both on xbox live playing at the same time.
