Скачать или смотреть Ubiquiti Unifi USG: Setting up VPN L2TP Over IPSEC

Short video that shows how I configured my Unifi USG to be a VPN server.
This video is merely a reference, I hope it helps you.

1) Download the config.gateway.json file posted by UBNT-MikeD post #10 on https://community.ubnt.com/t5/UniFi-R...

2) Look for your controller directory folder ( in windows it is located at
C:\Users\yourUsername\Ubiquiti Unifi\data\sites\default)

3) Copy the config.gateway.json file you downloaded in step 1 to your controller folder (see step 2)

4) Run a provision by creating a port forward rule in the GUI: Devices - USG router - Configuration - Port forward

5) Via CLI check and see if the config.gateway.json file configuration settings were added to your USG
