• I have a pfsense setup that has two LAN interfaces that I have set up as LAGG failover.
    It works as it should be. When the primary interface fails it switches over to the second one.
    My problem is that when the primary interface that failed comes back it will switch back to it.
    This breaks my flow of traffic as the other side is set to stay on the second port as the new primary and it makes the primary that just came back up the new secondary.

    My question is how can I keep traffic to stay on the secondary interface when the primary fails and comes back up.
    I have looked all through the GUI on Pfsense so this will probably be a system tunable or a config file that needs to be changed.

    I'm not sure you can, see: https://www.freebsd.org/cgi/man.cgi?query=lagg

    There is only net.link.lagg.failover_rx_all but I don't think that will help here.

    Do you have to use failover?


  • @stephenw10 said in LAGG interfaces help:


    Yes the reason I need to do Failover is because the two switches that are connected one to each interface don't stack and don't know each other. Had a switch failure and I'm trying to make an HA scenario so we don't have this happen again.
