Thought you might find this useful. It's the Cisco 827 config for the 5 static IP package using NAT. The one that is presently posted is for straight routing.

I also have to point out that this router works great with SBC DSL. None of the MTU issues that I had with other routers and I have been able to go months without power cycling.
