I wondered if openvpn works with mailinabox. I searched but didn’t find any results about that. So i decided to try. Installed pritunl for vpn. It uses openvpn but gives you amazing admin panel. Better than openvpn access server. I want to say, it works like a charm.
Only you have to give access to ports. Pritunl uses 9700 for its admin panel. Also you need to give access for vpn port.
You can do them with
ufw allow portnumber
