OpenVPN Wizard protocol defaults to "UDP IPv4 and IPv6 on all interfaces" causing problems
The OpenVPN Wizard's default protocol is "UDP IPv4 and IPv6 on all interfaces (multihome). However, when you are binding the service to a VIP (CARP or IP Alias), OpenVPN is unable to determine the address-family of the VIP and assumes "IPv6 Only".
So, if you use the wizard and bind to a VIP, OpenVPN throws TLS handshake errors and such. A user must go back and change the Protocol to "UDP on IPv4 Only" in order for it to work.
