I have a situation where I own both sides of a VPN tunnel between IOS boxes with no NAT at all. However, I have 2 servers that I now have to static NAT to two brand new IP addresses to meet network requirements on the "far" end. Unfortunately I never NAT on an IOS device--always a PIX/ASA or VPN-3000 box, and just haven't gotten the hang of it from the configuration examples.
A basic example of how to do this (without NATing any of the other traffic) would be greatly appreciated.
Just configure static NAT for both servers. Here's a sample config.
ip address 172.16.1.1 255.255.255.0
ip nat inside
ip address 192.168.1.1 255.255.255.248
ip nat outside
ip nat inside source static 172.16.1.254 10.1.1.254
172.16.1.254 --> Real Address of the Server.
10.1.1.254 --> Global address of the Server to which the far end user sends traffic to.
