Nat rules - 871w

Hey all,

I am in dire need of some help.  I am currently trying to open my NAT for use with Xbox live.  I have searched the forums and found great information but I cannot seem to get it to work for me.  If I do not use any port forwarding rules at all I can connect to live with a moderate nat setting.  Using what I have below it will not even connect to live at all...but what I have here seems correct.  Can anybody see anything I am missing or have incorrect?  I have my xbox configured with 192.168.1.102.

Have you tried if static 1-1 nat works? I see that you are getting one IP address via dhcp for the outside interface.

Based on the above article, it looks like you need a lot more ports than the two that you have open via static pat.
