Add Port Forwarding Rules

Add port forwarding rules to specify the destination ports of your USB Station 2 that will receive packages from

specific router ports.

To add port forwarding rules:

1 Click Create.

2 Do one of the following:

 If you want to create port forwarding rules for system services (for example, FTP), choose Built-in

application and tick the system services.

 If you want to create port forwarding rules for custom services, choose Custom port. You can use the

following syntax to specify port numbers and range:

 Use “-” to describe port range. For example, 6881-6890.

 Use “,” to separate ports. For example: 21,22 or 21,55536-55663.

Note:

 Some routers don't allow using custom ports for system services forwarding. See the documentation that came

with your router for more information.

 Each router port can be used for one forwarding rule only. Using a router port for two or more rules will cause

conflicts, and a warning message will appear on the screen. You need to set another port for the rule to avoid

conflicts.

3 Click Save.

You may need to wait for a few minutes before the rules start working, depending on the models of your routers.

To test whether your rules are working or not:

1 Select the rules you want to test and click Test Connection.

2 The result will be displayed in the Connection Test Result column.

Give USB Station 2 a DDNS Hostname

You can register a DDNS (Dynamic Domain Name Server) hostname for your USB Station 2, allowing it to be

connected anywhere by entering the hostname in the address bar of your web browser.

Once set up, you and your friends no longer need to remember the IP address to access your USB Station 2.

Simply type in the DDNS hostname on the web browser as you would when connecting to any website. After the

setup is complete, the hostname will always point to the external IP of your USB Station 2.
