Objective

Port Triggering provides for a more secure environment by closing off ports when they are not in use and are also used for special applications that can request a port to be opened on demand. Port triggering allows the computers behind a NAT-enabled router to access a special server or use a special application on the Internet.

The objective of this document is to guide the user to set up port triggering on RV016, RV042, RV042G, and RV082 VPN Routers.
