Hi,

We are trying to setup a firewall at our data center, I was wondering if some one could give us a list of the ports that must remain open TCP/UDP in order for Cpanel/WHM to work.

Besides from the obvious standard ports like SMTP, DNS, POP3, HTTP, etc.... what ports should we leave open? 2082, 2086, 2087, 2095, are there more?

Thanks!

That is it from in-bound connection ports.

Adam,

What about for out-bound ports?

if you begin blocking outbound connections, you are going to have problems syncing time (rdate) with the license server, and a few other things.
