Ubiquiti VPN Setup

This post is based on a support page on the Ubiquiti support site.  If you have a UniFi Security Gateway of the UniFi Security Gateway Pro this procedure will work for you. There are 3 steps to setting up the VPN; configuring the UniFi RADIUS server, creating the network, configure the client, in this case Windows 10.

All of the step in this procedure are the same except configuring the Windows client. I need to add steps 6 – 12 in the Windows 10 Client setup because the VPN could authenticate properly without the Challenge Handshake Authentication Protocol (CHAP).

All steps except for the client configuration will be done in  the UniFi Console, in the settings area. To get there click on the cogs in the lower left corner.
