Prestige 310 Broadband Sharing Gateway
Network Address Translation (NAT)
6-23
LAN computers dynamically take turns using the mapping based on the trigger port. There is no need to
reconfigure a new IP address each time you want a different computer (as you would with Port Forwarding)
to use the application.
6.6.1 Two Points To Remember About Trigger Ports
1.
Trigger events only happen on data coming from inside the Prestige to the outside.
2.
If an application needs a continuous data stream, that port (range) will be tied up so that another
computer on the LAN can’t trigger it.
Only one LAN computer can use a trigger port (range) at a time.
