API Port

Hi,
I can access all my ports(ftp, webport, tcp and etc..) except for my API port. I have also checked in the IP>services and infact API port is enabled. I don’t understand where i went wrong.

Cheers,
Botter

Are you able to access these services because there are appropriate port specific input filters in the firewall, or because there is a rule allowing access to any ports for the relevant interface?
