* Since the relay is an update server that needs to listen all the time on a port, Bitdefender provides a mechanism able to automatically open a random port on localhost (127.0.0.1), so that the update server can receive proper configuration details. This mechanism applies when the default port 7074 is used by another application. In this case, the update server tries to open the 7075 port to listen on localhost. If 7075 port is also unavailable, the update server will search for another port that is free (in range of 1025 to 65535) and successfully bind to listen on localhost.
