Is it possible to use 2 Xbox 360 consoles through a router to log onto Xbox live?

I have tried to connect 2 xbox 360 consoles through my router to get on Xbox live, but only one of them can get on. The other one has its DNS test fail on me even though the IP test passes. Can anyone help me figure out what is happening?Is it possible to use 2 Xbox 360 consoles through a router to log onto Xbox live?
In terms of using a router, this is absolutely possible. Make SURE that you are using a router indeed though. Routers and switches physically can look almost identical but the underlying layers in the operations that each perform are much different. A router should be transparent to your ISP and if you have NAT (Network Address Translation) turned on, it should issue 192.168.x.x IP addresses to your Xbox 360. Now if you have NAT turned off, both Xbox 360s will attempt to go to your ISP and register an IP address over the one connection. This will deny one or the other of a connection unless your ISP has issued you more than one IP address which usually costs about 5 dollars extra a month. If you really have a router, double check to make sure NAT is turned - along with DHCP on and then setup your Xbox 360s to automatically obtain an IP address from your router. Usually the routers should be configured to do this out of the box like linksys or netgear. Also double check your cables to make sure that you have your internet connection from your modem to the router plugged into the WAN port and that the Xbox 360s are on one of the LAN or Local Area Network ports. I currently have 2 Xbox 360s, 2 PCs and a laptop connected to the internet simultaneously through my router with no problems. Just think of your router as a splitter. Make sure that on the Xbox 360 that you are failing at the DNS level that the setting for your DNS server are identical to that of the console that is able to connect. Good luck and I hope this helps!Is it possible to use 2 Xbox 360 consoles through a router to log onto Xbox live?

Check your cables and such, this may be the problem, but you should be able to connect them up, as the XB360 uses the same Windows Networking Client as Windows XP.



Try turning on the other console first, and then check to see if it connects.



You could also try manually assigning different "static" IP numbers to them, though I'm not totally sure on how to do this.



Also, check with your ISP and have them do a line test, to see whether you can obtain the bandwidth necessary to connect 2 consoles.



Lastly, do both consoles show up on your routers internal log, (most routers have an internal IP number [check with your manual/manufacturer for this] that shows you what devices are connected to it, via their IP number).
