Bug #13035
closedNo default route following WAN Gateway Group PPPoE member failure
0%
Description
This is probably a twist on BUG # 12920 [[https://redmine.pfsense.org/issues/12920?tab=properties]]
Tier 1 of a Gateway Group is a PPPoE interface, 1gps.
Tier 2 of the same Gateway Group is a static IPv4 connection. 100mbps.
When the PPPoE Tier disconnects (and the simplest action is to push the disconnect button), the default route is removed.
The PPPoE Tier shows as "Pending" in the Gateways Status page.
The dpinger log show 5 consecutive "WAN_PPPOE ww.xx.yy.zz: sendto error: 65" error messages
There is no failover and the box is isolated from the world ;-(
The behavior is the same if the trigger is packet loss or member down.
Manually logging through the LAN and changing the "Default Gateway IPv4" restores connectivity to the Tier 2 member.
I do not know how "Member down" should be interpreted in the case of a PPP interface. Obviously, there is 100% packet loss here. Can failover occur in this case ?

- Status changed from New to Not a Bug
Seems closer to #12811 or maybe part of #11570 though it's also possible it's a part of your configuration. Not enough information here to definitely say it's a new or unique issue not already covered by existing bug reports. First thing to do is to try on snapshots and see how it behaves. Start a forum thread if it's still broken on snapshots.

Thank you. The test equipement to run the snapshot will be available next Monday.
I did not ask the question properly: how is "Member down" interpreted in the case of a PPP interface? And for that matter, hhow is "packet loss" interpreted for a disconnected PPP interface?
We plan to run the exact same configuration in the exact same hardware using the development snapshot from next Monday.

The results of the test are simple: Gateway failover occurs if the PPPoE gateway goes down (ie., removing the internet cable from the WAN port) or if the WAN interface is disabled. Gateway failover does not occur if the "PPP disconnect" button is pressed using the GUI Interfaces.
In the following tests, failure occurs in test #6: you can explicitly see that the PPPoE interfacte is the default route while the interface is in the "Pending" status,.

Simple workaround: don't touch that button!
