Lets say I have three inside addresses 10.10.10.1, 10.10.10.2, and 10.10.10.3. All three of these addresses will be translated to an outside address of 184.108.40.206 and I have PAT set up. My destination address will an outside address of 220.127.116.11.
When 10.10.10.1 initiates a connection to 18.104.22.168 I see the translation of 10.10.10.1:80=22.214.171.124:8000.
From my outside host of 126.96.36.199 could I initiate a connection back to the inside host and map that connection to a different port? For example I am sitting on 188.8.131.52 and I want to ssh to my inside client of 10.10.10.1. From 184.108.40.206 I type ssh 220.127.116.11:8000. When the packet hits my NAT router, I want the NAT router to MAP that 18.104.22.168:8000, back into 10.10.10.1:22.
Is this possible?
