Port Forwarding and Port Triggering on RV320 and RV325 VPN Router Series

Objective

Port Forwarding is a technology that is used to redirect packets that are sent across a network. This ensures that the packets have a clear path to the intended destination, which allows for faster download speeds and lower latency. The RV32x VPN Router Series supports port range forwarding and port triggering. Port range forwarding is a static port forwarding that opens a specific range of ports. This increases security risk as the configured ports are always open. Port triggering is dynamic port forwarding. When a device that is connected to the router opens a trigger port defined in the trigger rule, the configured incoming ports are opened. Once the trigger ports are no longer forwarded, the incoming ports are closed. Port triggering offers higher security since the configured ports are not always open, however a port trigger rule can only be used by one client at a time.

This article explains how to configure port forwarding and port triggering on the RV32x VPN Router Series.
