We just implemented a site to site tunnel with another network and now need to NAT addresses from our LAN through the tunnel. Not sure how to do this correctly, and without breaking anything else.
The internal network is 172.16.0.0. The tunnel allows traffic between 126.96.36.199 and 188.8.131.52. I need to translate 172.16.0.0 to 184.108.40.206 to get to 220.127.116.11. Is there a way to do this on the ASA? Or do I need a router in front of the ASA to NAT addresses? Currently 172.16.0.0 is being NAT'd outbound to a global pool for internet traffic, and that needs to stay in place.
