in my setup I'm using an OpenVPN client, connected to 3 different endpoints, and MWAN3 to do a load balancing and splitting traffic to use VPN or don't use it. Everything is fine with this configurations, but I experience some lost VPN connections.
To better understand the problem, I want to monitor the VPN endpoints and ping them using the 3 TUN interfaces.
Thus, is there a way to use multiple ping plugin instances, each ping a single server BUT using the appropriate interface?
Thanks in advance for your support!
