sends the reply through the Internet to the computer or wireless device that sent the web

Set Up 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 from 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 (a feature in Windows XP), enable Universal Plug
and Play (UPnP). For more information, see Universal Plug and Play
on page 105.
