To change the default port of OpenWrt, you can follow these steps:

1. Access the router’s management page by typing “192.168.1.1” into the browser to open the OpenWrt web interface.

3. Locate and click on the “Network” option in the management interface.
4. Select the “Firewall” tab in the network settings page.

After completing the above steps, the default port of OpenWrt will be changed to the port number you have selected. Make sure to choose a secure and not easily guessed port number when making the change to ensure the security of the router.
