I'm using 21.02 FW and downloaded the OVPN config file from Nord, put my credentials in and got the VPN to start. As soon as the VPN starts, I lose internet connection. I can still Ping out from what I'm seeing under Network=>Diagnostics but pulling up webpages isn't running normally. I have attempted to add the VPN interface as well as set the WAN zone in Firewall settings to tun0. I'm new to all this so I've been using the LEDE interface rather than command line.
For what it's worth, with VPN disabled, normal internet. With VPN enabled, no internet when connected to the POE brick or wirelessly.
If you followed that advice, please post the solution if you have an opportunity - as I'm curious to know how it was fixed. I'm sure someone else who searches and finds this thread would be grateful too.
Changing the DNS servers had no beneficial effect. When VPN is activated, I lose internet yet still can ping addresses and get back good results as seen in the picture.
Solved!! I went back into Network=> Firewall => Zones => WAN => Edit => Advanced Settings => Covered Devices=== and selected: Ethernet Adapter: "tun0" (VPN)
