My current setup involves an OpenVPN TAP connection and a WiFi network. The WiFi network has it's own dedicated network interface. I have bridged the TAP interface to the WiFi interface. Currently, if a device connects to the WiFi network, it's as if it connected to the same network as the OpenVPN TAP host.
I am attempting to add a failover to my setup. So, if my main TAP interface is not available for some reason, I'd like traffic to be router through a secondary OpenVPN instance. (I have already created this secondary instance, which is TUN in this case).
I attempted to use the mwan3 package to implement this fallback. As far as I can tell, I've done this process correctly for both of the OpenVPN interfaces, as the Load Balancing status page shows the two VPN interfaces correctly.
However, I can't find a way to access the... output(?) of mwan3? Is there a way to perhaps have the mwan3 route to a single downstream interface (that I could bridge to the WiFi network), and mwan3 handles the upstream switching between the two OpenVPN profiles?
I may be trying to go about this the wrong way. Any suggestions welcome
