OpenVPN on Failover GW Master and backup problem

[rirak]

I have two opnsens servers in master/slave configuration.
I have two WAN interfaces.
I need to have failover for OpenVPN

When I set the OpenVPN interface to a failover GW, the OpenVPN service on both servers starts. They both try to connect to the remote OpenVPN server and they both succeed in this alternately. Which means no consistent connection from one site to the other. This is basicly the same problem as choosing a non-CARP IP.

Any ideas? Is this a bug or a feature?
