ProSecure Unified Threat Management (UTM) Appliance Reference Manual
Firewall Protection 5-47
v1.0, January 2010
Note these restrictions on 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 short time-out period
before the application can be used by another PC. This time-out period is required so the UTM
can determine that the application has terminated.
To add a port triggering rule:
1. Select Network Security > Port Triggering from the menu. The Port Triggering screen
displays. (Figure 5-28 shows a rule in the Port Triggering Rule table as an example.)
2. Below Add Port Triggering Rule, enter the settings as explained in Table 5-10 on page 5-48.
Note: For additional ways of allowing inbound traffic, see
“Inbound Rules (Port Forwarding)” on page 5-6.
