I know it is complicated but then you can always give it a try..

These things look complicated until you understand the workings of the router in question. If you just read the post/link i sent you, you will find the part that relates to your question, i can not give you a short cut because it would not work. It depends on what kind of network you have setup, every ones network is different (routers, switches, ip addresses (inside and out)) So the best i can give you in terms of the help you are asking for is (like i said) in my earlier post. If you can give us a good idea why you need to have the setup this way, then maybe i can scratch my head a bit more and give you a solution.

Please post back if you have any more problems or questions.

Advertising your NAT pool to your ISP doesn't make sense since they already know they assigned the public addresses to you can don't care what your private nonroutable addressing is.

If you want your ISP to know your 2800 is on their network I'd say use OSPF [that is if their routers will take your 2800 advertisments]
