Friend did a post in the hardware section but ill let people reading this forum as well. Microsofts routers do not work with msn game zone? Why might you ask ? Because the DMZ is not a true dmz it still filters those ports. SO, you can get into the zone but when you launch a game it crashes back to desktop. This Non DMZ , DMZ also interferes with a variety of other apps. You would think they would have tested this. So if you have any sense, dont buy one. Linksys and Dlink work fine. You will not get the seamless integration with othe ms products that you would hope for expect for.
