Ok, for anyone else who is unable to get port forward OpenVPN to work with multi wan, where you forwarded all vpn traffic to local host. The issue I had above was a result of allowing the default protocol listing for OpenVPN. I left it at UDP for IPv4 and IPv6 on all interfaces (multihome). Once I changed it to UDP for IPv4 only, everything worked as described in the online manuals. Good luck out there!
