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 (
You need a port forwarding rule only when two conditions are met:
- You want to use a direct connection between the Viewer and Host.
- 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.
