Goverlan uses one TCP Socket port for client/server communication. The default port is 21159. However, it can be changed to fit your firewall infrastructure. To use a non-default port number, you must configure both the Goverlan Agents and the Goverlan Clients with the new port number.
Once the Goverlan Agents have already been installed on a machine, you can view and modify its communication port by opening the Goverlan Remote Control applet in the Control Panel. Click on the Communication Port button of the applet and change the port number to the desired value.
This setting can be distributed to a set of machines. See: Settings Distribution - Overview
To change the port numbers used by Goverlan, open the Settings window and select the Network Settings category.
