Description
One of my users cannot log-in using opevpn, since the activation of the firewall/DNS blocking is failing (log is attached).

As "no end points available from endpoint mapper" is RPC related and opening the WFP engine itself seems to fail (which doesn't require any extra privileges), I suspect some required firewall related services are not running on the host or some other security software is interfering with it.
The more verbose log linked to at https://community.openvpn.net/openvpn/attachment/ticket/1146/charite-schenkc.log is with interactive service not running (or GUI run as admin?). Please start the GUI as limited user, ensure interactive service is running, set verb=4 and post the logs. Also check the eventviewer to see any additional errors logged there by the service.
The log linked to through forum.netgate.com is using the service but not verbose enough (use verb=4).
