Note: Port 5065 is used only on a branch office server that:

Uses only the eth0 network interface

Runs the IP Telephony and Messaging software configuration

Back End Server Ports The Back End Servers (Accounting Server, Authentication and Directory Server) use these ports in order to provide redundant service to remote clients. Normally, these ports can be blocked by the internal firewall.

However, if the redundant servers are separated on either side of the internal firewall, the firewall must be configured to not block these ports.
