Firstly, are you going to host any servers on your private network? If so, you're probably trying to "double NAT". Check out this post for some views on the subject.

If you do want to go ahead with it, you will need to:
1. Set the external interface of the "outer" router to the IP provided by your ISP.
2. Select a private subnet to which both the internal interface of the "outer" router, and the external interface of the "inner" router will belong to.
3. Finally, select another private subnet which will exist behind the "inner" router.

The following step is not required if you are not hosting any services behind the routers:

You will then need to setup port forwarding from the external interface of the "outer" router all the way through to the internal network behind the "inner" router.

I'll give it a shot...Thanks for the info.
