I recently moved to a new flat and went with BT and their new home hub stuff. Everything works like a charm. My laptop works perfectly, my PS3 connects perfectly and so does my Wii. So im a happy bunny until now... Ive just noticed that although i can connect to xbox live with no problems at all when I run a network test I am getting a strict NAT setting. This should be set to OPEN otherwise you can not join or talk to a lot of people on xbox live. I am quite up to speed with how routers work and things like upnp. I have checked everything on the router and upnp is on. This usually is the cause of the problem but makes no difference with my xbox. The REALLY weird thing is I have sometimes randomly got an OPEN return when doing a xbox live test for my NAT but it seems to randomly switch between OPEN, MODERATE and STRICT whenever it feels like. It is really frustrating and i dont know what more I can check on the HUB to make this stay as OPEN. I previously was with BULLDOG and was using a d link router. Once I activated upnp on the router I never had a problem with the NAT setting at all. Ive rung xbox support and they are useless. BT are an approved provider for xbox live so I didnt think i would have such problems.. Anyone got any ideas reg settings on the router I can ammend or experiencing the same problem?
