10.1.2.2 Two Points To Remember About Trigger Ports

1 Trigger events only happen on data that is going coming from inside the ZyXEL Device
and going 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.

10.2 General NAT Screen

Use this screen to enable and disable port forwarding, trigger port, and other NAT rules. To
open this screen, click Network > NAT > General.
Note: Make sure your firewall allows the traffic you specify in the NAT screens to be
forwarded through the ZyXEL Device. You might have to create a firewall rule.
