2.
The router receives the message and finds your port forwarding rule for incoming
port 80 traffic.

The router changes the destination IP address in the message to 192.168.1.33 and
sends the message to that computer.
4.
Your web server at IP address 192.168.1.33 receives the request and sends a reply
message to your router.

Manage port triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
•
An application must use port forwarding to more than one local computer (but not
simultaneously).
•
An application must open incoming ports that are different from the outgoing port.
With port triggering, the router monitors traffic to the Internet from an outbound “trigger”
port that you specify. For outbound traffic through that port, the router saves the IP
address of the computer that sent the traffic. The 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.
NOTE: 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 N Play (UPnP). See Improve network
connections with Universal Plug and Play on page 120.
