ProSafe VPN Firewall 50 FVS338 Reference Manual
4-34 Firewall Protection and Content Filtering
v1.0, January 2010
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 this VPN firewall cannot
be sure when the application has terminated.
To add a port triggering rule:
1. Select Security from the main menu and Port Triggering from the submenu. The Port
Triggering screen will display.
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, select either TCP or UDP 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).
Note: For additional ways of allowing inbound traffic, see “Creating a LAN WAN
Inbound Services Rule” on page 4-9.
