I have a Cisco firewall, and using nat. I have an official internet adress on the outside interface, and a Ubuntu server on the inside interface. I have configured NAT and security rules.
Problem is. When I open port 80 I am able to connect to the Ubuntu machine from outside. However, when I try port 22 ( SSH ) it will not pass trough. If I move the Ubuntu machine to a DMZ all ports work. IT seems that the lower ports on the inside interface is blocked whatever I try to do.
Need help to enable port on port 22 on the inside interface.
