Hi all. (waiting for TAC support to register me)

I'm trying to find information on setting up a Dynamic NAT for my 1841 using the SDM. I know how to do the static NATs and they seem to work fine. However, our Japan office would like Dynamic NAT. Where can I find info on how to set this up?

I have a range of server addresses on my network (E0) from to The addressing I have for these on the "outside" (E1) is to 172.25.40/16.

I tried to set this up, but it seemed that the router duplicated all of my server addresses and my systems weren't happy.

Thanks for any assistance.

I got it working. I reset to factory and configured it again and it works.
