I have posted, that I have troubles with the configuration of a OpenVPN-Server with HAProxy in Post #283. I have to apologise for the confusion I have caused. The HAProxy config was absolut perfect - thanks to author of this thread - the problem was a incorrect certificate in the OpenVPN server - today I've got it solved! The right configuration can be found in post #171 - that works perfect! The hint I could give is that you have to put the virtual adress of your VPN server in the "real server" IP adress field.
