NAT – Port Triggering (Example)
Example: How to create and delete a Virtual Server rule
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.
Manually create a rule of your own If Application does not contain the application you are looking for.
Click Apply to save the settings.
New rules will be listed in the Port Triggering table.
To remove a rule, simply click the check-box of the unwanted rule then click Remove to delete it.
