Flaky PPPoE and Dynamic gateway causes stale firewall states



  • Hey guys,

    I have a pfsense installation at a site that has a pretty flaky PPPoE connection with a dynamic gateway. Whenever the PPPoE connection is re-established the WAN default gateway changes and all my asterisk trunks become UNREACHABLE until I manually clear the states.

    I know that if my IP address was dynamic and changed the firewall states would be reset. I would assume that the same would occur if my default gateway were to change, but it does not.

    Bug?
    Feature?
    Possible setting that will resolve this?

    I have tried all the firewall optimization settings and making SIP not use states, but none of that helps.

    Thanks,
    – Jascha

    Looks like it might be related to this:

  • Yeah, I looked at that bug, it's actually complete. My problem is that the IP doesn't change, just the default gateway.

    I need to figure out how to trigger a state table reset when WAN default gateway changes.

    There are references to the gateway in the rules, and likely the states, but I had thought when PPPoE disconnected it killed all states to the old gateway.
