Unable to join Xbox Live Party Chat with Open NAT

My friend and I both have open NAT, yet we are unable to connect to Xbox Live Party Chat or for example in Halo 4. I also have all of the correct ports forwarded (although redundant, UPnP is enabled as well). What else could possibly prevent us from connecting?

Hi,

Please do not forward ports as well as using UPnP and forwarding can cause issues so please use one or the other not both. What NAT status does your friend have?

We will need more information on both set-ups really

Please read:- forums.xbox.com/.../811997.aspx

And post back yours and your friends details in full (the bits that are in bold on that post) so that people may help

If you are wireless can you also state whether you are using the white or black external adapter or the Xbox 360S Internal adapter

Thanks

UPnP is now disabled. Forwarding ports 88 (UDP) and 3074 (UDP and TCP). Also forwarding ports 80 (TCP) and 53 (TCP and UDP) for good measure. All ports are forwarded to the Xbox's IP address (the IP address is a reserved IP address in the DHCP address pool). I should also mention that technically the ports are forwarded via the router's Virtual Server feature. NAT status reports Open.

My friend claims his NAT also reports Open, but I do not know his settings.

If my NAT status is Open, doesn't that mean I have all the correct ports forwarded? I do not understand what it means technically speaking when your NAT is moderate or strict. What does that mean from a networking standpoint?

Do you have this issue with other friends? If not I would say your set-up is fine

As far as I know, he's the only one I have this problem with. But again, if his NAT is Open what else could prevent connection?

What is it that you're saying? I consider it my problem when I can't connect to him.

What I mean is... if he is the only friend you cannot connect to, it could well be that your own set-up is fine and it is his set-up that needs looking at, is it possible for him to post his details here?
