Using communication ports between IPortalDoc and Light

What are the communication ports used between an IPBrick server with iPortalDoc and another IPBrick server with Light?

The necessary ports to allow the communication between iPortalDoc and Light servers are:

• HTTP and HTTPS (tcp/80) (tcp/443)
• Database (tcp/5433)
• LDAP (tcp/389)
• IMAP (tcp/143)

Notes:

• There is always a two-way communication.

• PING has to be working between the 2 servers because of Light's IPBrick, i.e., both servers need to be able to ping each other.
