Port Triggering
Port triggering is a way to automate port forwarding with outbound traffic on predetermined ports
(‘triggering ports’), incoming ports are dynamically forwarded to the initiating host, while the
outbound ports are in use. Port triggering triggers can open an incoming port when a client on the
local network makes an outgoing connection on a predetermined port or a range of ports.
Click
Add
to add a port triggering rule.
Interface:
Select from the drop-down menu the interface you want the port triggering rules apply to.
Application:
Preinstalled applications or Custom Application user can customize the utility yourself.
Custom Application:
It is a kind of service to let users themselves customizes the service they
want. Enter the user-defined service name here.
Trigger Port
Start:
Enter a port number as the triggering port starting number.
End:
Enter a port number as the triggering port ending number.
Any port in the range delimited by the ‘Start’ and ‘End’ would be the trigger port.

Open port
Start:
Enter a port number as the open port staring number.
End:
Enter a port number as the open port ending number.
Any port in the range delimited by the ‘Start’ and ‘End’ would be the preset forwarding port or open
port.
Protocol:
select the protocol this service used: TCP/UDP, TCP, UDP.
Set up
An example of how port triggering works, when a client behind a NAT router connecting to Aim Talk,
it is a TCP connection with the default port 4099.
When connecting to Aim Talk, the client typically makes an outgoing connection on port 4099 to the
Aim Talk server, but when the computer is behind the NAT, the NAT silently drops this connection
because it does not know which computer behind the NAT to send the request to connect.
So, in this case, port triggering in the router is working, when an outbound connection is attempted
on port 4099 (or any port in the range set), it should allow inbound connections to that particular
computer.
1.
Select a Server Name from the drop-down menu, then the port will automatically appear, modify
some as you like, or you can just leave it as default. Remember to enter your server IP Address.
2.
Press
Apply
to conform, and the items will be list in the
Virtual Servers Setup
table.
