Cisco IOS - how to config static nat not to NAT over the VPNs

Hi everyone,

I need some help.

I've configured a site-to-site VPN between two IOS routers. One of the routers already had a static NAT (172.16.100.1 inside to public IP), however this static NAT is preventing the remote VPN hosts from accessing the 172.16.100.1 host as the router tries to NAT the response to the configured public IP.

Does anyone know how to use static NAT for the inside to outside, but do no NAT on the inside to outside VPN traffic?

I know how to do this using a route-map for 'overload' dynamic NAT, but I can?t see how you can use a route-map on the static NAT statement.

Any help you can provide would be appreciated.

Chris
