I have an issue where I can VPN client to IOS router 12.2.15T and everything works with the exception of the Statically assigned NAT'ed servers. Unless I remove the NAT assignment, I cannot access the server. Any ideas here?
The Static NAT's always exist. Meaning that you have to do policy routing to make the router think the traffic is not coming from the "ip nat inside" interface going to the "ip nat outside" interface. Basically you route the traffic out a loopback interface and it comes right back in then out thru the VPN without being NAT'd.
Take a look at this, it will resolve your problem:
