How to Configure and Use NordVPN on pfSense 2.5

pfSense 2.5 firmware-based routers now provide support for WireGuard VPN clients.

But fret not, you can configure the OpenVPN client of NordVPN on your pfSense router and encrypt your complete web connection. Go through the following steps to learn how. 


If you’re using pfSense 2.4.4 or 2.4.5, check our separate guides.
