Mapping one public IP to many private IPs via different ports is normally supported in some firewalls.
What about Cisco PIX or ASA? Is this possible that we can configure that if somebody hit public IP 22.214.171.124 on port 8000 then take it to 192.168.1.1 and if same public IP got hit on port 9000 then map connect to 192.168.1.2. Is this possible? If yes then please somebody help me.
Yes this is possible.
