4-28 Firewall Protection and Content Filtering

Note these restrictions with Port Triggering:
• Only one PC can use a port triggering application at any time.
• After a PC has finished using a port triggering application, there is a time-out period before the
application can be used by another PC. This is required because the VPN firewall cannot be
sure when the application has terminated.
To add a port triggering rule:
1. Select Security > Port Triggering from the main menu. The Port Triggering screen is
displayed..
2. Enter a user-defined name for this rule in the Name field.
3. From the Enable pull-down menu, indicate if the rule is enabled or disabled.
4. From the Protocol pull-down menu, choose either TCP or UDP transport protocol.
5. In the Outgoing (Trigger) Port Range fields:
a. Enter the Start Port range (1 - 65534).
b. Enter the End Port range (1 - 65534).
6. In the Incoming (Response) Port Range fields:
Note: For additional ways of allowing inbound traffic, see “Inbound Rules (Port
