Two examples: Dynamic port forwarding (DPF) is an on-demand method of traversing a firewall or NAT through the use of firewall pinholes. Wenn ein Rechner über eine Anwendung, deren Ports im Port Triggering festgelegt wurden, Daten ins Internet sendet, speichert der Router die IP-Adresse dieses Rechners und leitet die eingehenden Antwortpakete, entsprechend an diese IP-Adresse weiter (zurück). Select the Firewall tab. Unturned 2.x and 3.0 use different ports in their forwards, the default port for 2.x is 25444 and the default port for 3.0 is the port range 27015-27017(3.0 uses three ports that need to be forwarded.). The source address and port are, in this case, left unchanged. When configuring port forwarding, the network administrator sets aside one port number on the gateway for the exclusive use of communicating with a service in the private network, located on a specific host.

Da der entsprechende Netzwerkdienst nicht von dem weiterleitenden Computer selbst geleistet wird, ist die Bezeichnung virtueller Server irreführend. An application that provides an Internet-based service may discover such gateways and use the UPnP IGD protocol to reserve a port number on the gateway and cause the gateway to forward packets to its listening socket. A certain video game might use ports 3478 through 3480, for example, so instead of typing all three into the router as separate port forwards, forward that whole range to the computer running that game. Port Triggering erweitert damit die Technik der einfachen Portweiterleitung.

Sobald der Port wieder geschlossen wird (siehe oben) ist es wieder nicht möglich, eingehende Anrufe zu empfangen. (On Linux kernels, this is DNAT rule).

Through SSH, this can be accomplished by opening the virtual network computing port (5900) and including the destination computer’s address.
