multi vpn wireguard and error with monitoring

[FredFresh]

I have 3 wireguard connection with Proton VPN, manage them as serial system (if first fail, the second is used, so the third and as last the regular wan).

If, for any reason, the wireguard connection drops and the monitoring service reach the 100% of fail (and the gateway is marked as offline), its gateway never comes back ONLINE even if the VPN peer is still working.

Using the laptop and trying to reach the monitoring IP of the first VPN, I see that the flow goes through the second VPN and NOT the first one.

Using the firewall "live view" I can't see the opnsense pings to the monitoring ip, BUT when the first gateway is down I see a repetition of blocked connection to the first VPN gateway coming from its Monitoring IP.

I tried to forcibly route the communication towards the MOnitoring IP through its VPN gateway (using a floating rule in the firewall) but it didn't work.


If I change the maximum acceptable LOSS level of the first VPN to 100%, than the communication start again to flow through its gateway and the monitoring IP works again and the gateway is again ONLINE.

Please, anyone has a solution?
