Feedback on Routing and Multi-WAN — Using Multiple IPv4 WAN Connections
I'm told that when https://docs.netgate.com/pfsense/en/latest/routing/multi-wan.html#trigger-level says:
Triggers when the monitor IP has 100% packet loss."
....that is incorrect/incomplete, and the description in the book at https://docs.netgate.com/pfsense/en/latest/book/multiwan/load-balancing-and-failover.html of:
Marks the gateway as down only when it is completely down, past one or both of the higher thresholds configured for the gateway."
