      Primary WAN gets high packet loss intermittently. It failovers to the cellular backup. That works.

      The problem is that the packet loss lasts 10-90s. So pfSense is flapping the gateway between Tier 1 and Tier 2 quite rapidly.

      I’ve tried it on packet loss and on member down. Member down doesn’t really work out well because the packet loss may not trip the failover but will be pretty bad.

      My question: Is there a tunable or some hidden setting to say “When T1 goes down, flip to T2 and stay on it for Xseconds”? Basically I’d like to have it failover to the cellular and stay there until the primary has been in a good state for at least 5m.

      If there isn’t, how do I submit a feature request? :-)

        I haven't seen such an option. The solution itself looks good, but could it be that the load on the network through pfSense itself is causing the packet loss and/or these are issues on the provider's side?
        https://redmine.pfsense.org/ for the feature requests and bug reports.

          @w0w no, it's a carrier problem (currently). Either a node is failing or a customer on the node is sending noise back to the node, causing high packetloss everyday between 2p & 4p. I can set my clock to it almost....but it causes pfSense to flip sheep with the failover.

          I had a truck rolled today, showed them the latency logs from 2 different addresses in the neighborhood. They agreed it was a "them issue".
