1. At first, you need to login to the control panel of your Asus router. Usually, by default, it is 192.168.1.1
You should type this address in the address bar in a browser. The window will prompt and will ask for username and password to access the control panel. Use your set username and password. If you have never changed the password, the credentials should be: admin/admin or admin without the password.
2. After you are logged in to the Control Panel you should go to the VPN tab on the left side of the window.
3. Click on the VPN Client in the opened window.
4. Click on Add profile button at the bottom of the window.
