If you are looking for a tool to manage ports from CLI, then I use UFW.
If you need a tool with GUI and you are on a Linux server, then maybe you should ask within the Community of the Control Panel you are using. For example,
if you use cPanel, there might be a cPanel Plugin
if you use CWP, maybe there is an opensource Module for it etc
If you need GUI and you are on a Linux Personal Computer, I just saw one called GUFW. http://gufw.org/
