How do I set up port forwarding for the Host?

Port forwarding (also port mapping) is a technique of translating the address and/or port number of a network packet to a new destination. Port forwarding allows remote computers, located on the Internet, to connect to a specific computer or service within a private local area network (LAN).

Port forwarding rules are set on routers or other network devices that act as an Internet gateway for other computers in a local network. To create a port forwarding rule and access Remote Utilities Host from outside the local network, you need to know:

  • The Host computer local IP address (for example,
  • Host listening port (5650 by default)

You need a port forwarding rule only when two conditions are met:

  1. You want to use a direct point-to-point connection between the Viewer and Host.
  2. The Host PC accesses the Internet from behind a router/firewall and doesn't have an external IP address of its own.


If you connect using Internet-ID you don't need port forwarding.
