I have the following configuration on an ASA running 8.4 already;
object network SERVER-01 host 192.168.0.1 ! object network SERVER-01 nat (Inside,Outside) static interface service tcp 3389 5001
I have this config repeated several times to allow RDP to multiple machines behind the ASA, on different ports; 5001 forwards to one server, 5002 to another, and so on.
For this one server in the above config though, I want to forward port 5555 publicly to port 5555 at the same private IP, 192.168.0.1.
If I try to enter the above config but with different port numbers, it is overwritten, I can't seem to add an additional NAT entry, only replace that one. This indicates I can only have one port forwarded to each internal IP at a time. Is that correct, or can I forward various public ports to an internal host, but using some other method? If so, how?
