As a temporary solution, see if you can find what you're looking for in /etc/openvpn (enable SSH on the router and connect using WinSCP software)Feature suggestion: is it possible to give the possibility to export the actual configuration of each openvpn CLIENT in a .ovpn client?
And also I don't know if that's possible, but if it was possibly to export also on the same file the policy rules it would be perfect.
