modem router temporarily opens the incoming port or ports that you specify in your rule and forwards that incoming
traffic to that destination.
Port forwarding creates a static mapping of a port number or range of ports to a single local computer. Port triggering
can dynamically open ports to any computer when needed and close the ports when they are no longer needed.
If you use applications such as multiplayer gaming, peer-to-peer connections, real-time
communications such as instant messaging, or remote assistance, enable Universal Plug and
Play (UPnP). See Improve Network Connections With Universal Plug and Play on page 146.
