Ports Used by Remote Utilities
Direct connection port
To use direct connection you must open the inbound TCP port
5650 on the computer where Host or Agent is running.
During Host installation the program automatically adds an "allow" rule to your Windows firewall on the Host PC. If you use different firewall software, you need to manually open this port in the firewall settings.
5650 is the default value. You can change it in the Host network settings. If you changed the port on the Host side, remember to update the port in the corresponding connection properties (the Network tab) in the Viewer address book.
Internet-ID connection ports
Opening an inbound port is not necessary for the Internet-ID connection. Only certain outbound ports need to be open—specific values depend on whether you connect via our public Internet-ID service or your self-hosted RU Server.
You cannot change ports used by the public server. However, ports used by RU Server can be customized.
Remote Utilities uses the outbound TCP port
5655 to communicate with our public server. If this port is blocked, the program automatically attempts to use the TCP port
