ER-Lite OpenVPN Client Dual WAN

Hi,

I did configure an ERL mit Dual WAN and OpenVPN client connection to an VyOS server. WAN Failover for Internet traffic is working good. OpenVPN also works good when only one WAN-Port is connected. Else I am loosing at least 50% packets. How can I configure WAN Failover for OpenVPN client?

I would also be willed to pay for it if someone could configure it for me.

Thank you
