Is it possible to NAT to 1 of 2 different inside destination IP's based solely on the external source IP address?
There is something similar described but it doesn't work:
access-list WEB permit tcp host 10.1.2.1 22.214.171.124 255.255.255.255 eq 80
access-list TELNET permit tcp host 10.1.3.1 126.96.36.199 255.255.255.255 eq 23
nat (outside) 1 access-list WEB outside
global (inside) 1 188.8.131.52
nat (outside) 2 access-list TELNET outside
global (inside) 2 184.108.40.206
One final follow-up to this conversation (just for completeness). If you happened to use policy-nat, please note that it does not support using ports in the ACL. The ACL must only contain IPs/networks and no ports.
Sorry for not mentioning that sooner.
