Flaky PPPoE and Dynamic gateway causes stale firewall states

[Yoshizmo]

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.
