I didn’t test a VPN provider yet. If anyone does, feel free to let us know the result. Note that Wireguard is already available, as you can see in the options above.

EDIT/Feb 29, 2022: Now in the L5’s main Settings app, under the Network category, there is an option for adding a VPN connection. I think this is new, but I might be mistaken.
