Note: Only one computer can use a port triggering application at any time.
After a computer has finished using a port triggering application,
there is a short time-out period before the application can be used by
another computer.
To configure port triggering:
1. In the main menu
, select Security > Port Triggering. The Port Triggering screen
displays.
2. Specify the information for port triggering:
• Service Name. Ente
r a name for the rule, up to 30 characters.
• Service User. The co
mputer on the LAN that can use the port triggering rule to create
a dynamic inbound mapping to it. There are 2 options:
- The port triggering rule is applied to all computers on the LAN. That is, any
compute
r on the LAN can use the rule and make the router to open a dynamic
mapping to it.
- The p
ort triggering rule is applied only to the
user-specified computer on the LAN.
• Service Type. Defines whe
ther the traffic is TCP or UDP.
• Triggering Port. The d
estination port number of the traffic. That is, when there is a
packet from a LAN computer that the rule is applied to, with the specified service type
and destined to the specified triggering port, the router creates a rule for dynamic
mapping to the LAN computer.
• Required Inbound Connection.
This defines what the dynamic mapping is. The
connection type defines whether the dynamic mapping is for TCP traffic, UDP traffic,
or TCP and UDP traffic. The open port range is specified by the starting port and the
ending port, and this defines the port that the dynamic mapping is applied to.
3. Click Apply to
save your settings and activate the port triggers that you have enabled.
