Endpoint Agent to Endpoint Server communication is over port 10443. This port can be changed in the Enforce console, under the Endpoint Server configuration page:
NOTE: The Endpoint Agent's port number (the one used to connect to its Endpoint Server) can be set during the installation, or during post installation by changing the port number setting in the SQLite database. This can be done by using vontu_sqlite3.exe located in the installation package in the Tools directory. A re-start of the Endpoint Agent process will cause it to update its port number. Please refer to this KB for using vontu_sqlite3 - Change a DLP agent from one Endpoint Server to another:
