How to open some ports from my Whm Cpanel?

[plimper]

Dear support and members of this board.
I run on a linux centos based Whm Cpanel and i want to open the following ports.

28934 tcp/udp
20500 udp
20510 udp
443 tcp
3074 tcp
5223 tcp

Can anyone guide me on how can i do that?

Unless traffic is explicitly blocked by a firewall configuration the ports should be "open."

If the firewall configuration is unknown or if you are seeking a simplified interface for firewall setup I would consider trying CSF that is mentioned in the following forums thread: Third Party Applications Available for cPanel/WHM - cPanel Forums

Reference links for "ConfigServer Security & Firewall" (CSF):

Hi,

Which Firewall did you installed on the server? You can open/block the port from the firewall configuration itself.

Plimper,
If you have installed APF or CSF, you can open those ports from your WHM. Just go to Home >> Plugins and you will find the icon to access the firewall settings there.
There are too many docs available online to know how to install APF of CSF. Takes only a couple of minutes to get them installed
