basically, you have internal IP addresses and an external IP address. Your external IP is the one provided by your ISP, and normally takes to form of something like: 81.149.x.x This IP address is what is 'seen' on the internet.
Internal IP addresses typically appear in the form of 192.168.x.x Each PC or Xbox on your home network will have been assigned one of these addresses so that they can communicate with each other. To communicate on the internet, your router will translate the internal IP to your external IP so that it can 'talk' to other computers online. This, basically is what your NAT does.
Your router will be set to assign the next available internal IP to each device that is connected. There is no need to change this setting at all.
On your Xbox you should be able to assign an available internal IP address to the machine.
You can then open the ports on the router **for the IP address that you have assigned to the xbox**
I think what seems to be happening is that the router is assigning different IP addresses the the xbox each time it is turned on. As you will have only opened the ports for one internal IP address, it will not work properly on other internal IP addresses.
I hope this makes sense to you! Let me know if you need any more help!

i think there is a bit of confusion...
the static IP given by your ISP is a WAN IP
the IP for your xbox should be a LAN IP
your router handles the translation of the WAN IP to the LAN subnet.
therefore, you should not assign the IP given by your ISP to your xbox. it should go in the WAN IP configuration of your router. if your ISP says your router doesn't support it, i'd take their word for it IF they are the ones who supplied the router/modem to you.
you can assign a static LAN IP on almost any device, including your router. but the LAN IP is for devices on YOUR network only...
SO, this means your router could have static WAN IP and ALSO a static LAN IP, and the two are not the same thing.
to try to simplify...
you shouldn't need a static WAN IP just for xbox live. people use static WAN IP's for web hosting, and stuff like that. i think it's safe to say that a static WAN IP is not your problem with XBOX LIVE.
that said... XBOX LIVE has been flake-y as hell for the past 2 - 3 weeks. Microsoft has acknowledged the problem, and said that it's due to a larger than expected number of new sign ups over the holidays.
are you sure your LIVE issues are YOUR issues and not the terrible state of LIVE recently? last night was the first time in weeks that i was able to play multiplayer without f-ing around with things...
