Port forwarding

How it is used

Common in small offices and home setups: engineers set up, add or remove port forwarding on the router or firewall for cameras, game servers or remote access. Opening ports to the internet carries security risks, so many companies prefer a VPN.

Example sentences

1. We set up port forwarding so that port 8443 on the public address goes to the camera recorder.

2. Remove the old port forwarding rule for RDP; it's a security risk.
