Marcelo,

There are different types of firewalls in Cisco IOS, and it depends on your particular configuration how the ports should be opened. Can you post your current running-config (removing the sensitive information, of course)?

Best regards,

Peter

Hi Marcelo,

If you want open the above ports from outside (internet) you need to have configure NAT & PAT for that particular server in order to accessible from outside through the specific ports.
