I'm curious if its possible to use a static (inside,outside) for my server to receive connections from the outside, but reply with my global NAT IP?
Server1 : 10.10.10.10
Public IP : 22.214.171.124
static (inside,outside) 126.96.36.199 10.10.10.10
access-lists are opened etc.
How can I control the NAT procedure to disable the server responce from being NAT'ed to the static. And being NAT'ed through my global statement instead?
I've scanned through the cisco NAT documentation but I might have missed it.
No, it can't - not over the same connection (TCP stream). The server can reply via the same NAT'd IP and port and tell the client to connect to a different IP address/port. Or, the server can ask the client what address IT is listening on, and connect to the client on that port via a different NAT'd address. That's kind of what FTP does with port 20/21.

AFAIK you can't do this because the static statement is bi-directional so it applies both to the inbound and outbound traffic.
