VPN failover to WAN
I've set up my pfSense to send traffic via VPN (AirVPN in this case) instead of directly through WAN.
Is it possible to set some sort of a failover so that when:
VPN throughput drops below a certain threshold
VPN/server is offline (shouldn't really happen but…)
the traffic would be routed directly through the WAN?
UPDATE: this is probably not going to be AirVPN as my 50/50 (without VPN) connection yields a 0.5/0.2 (with AirVPN)…
