PPPoE WAN does not restart correctly after reconfiguring interfaces.

w0w

@Malec
Same for me.
I still encounter a race condition that causes mpd to start twice and get stuck, but I wrote my own script as a workaround. Not sure what the real status of the problem is. Still waiting for development snapshots available to re-test.

@w0w Were you able to test with the older 24.08 public snapshot?

w0w

@stephenw10
Yes, it is my current snapshot, so the problem remains the same.
However, I should point out that my configuration is far from standard. I also use CARP for failover, VIP addresses on a PPPoE parent interface, and much more, which is why I don’t want to file a bug report prematurely. Additionally, there is hope that something may have changed in the newer code.

stephenw10

Hmm, OK. Well with any luck we should have a new Plus dev snapshot very soon so hopefully you can test that and at least confirm if the issue still exists. Though there is a lot of new stuff so I anticipate some issues initially.

@stephenw10
Unfortunately, yes, the issue still exists.
I am using an unsupported CARP configuration to maintain PPPoE links automatically. There are two firewalls, and the parent PPPoE interfaces on both are configured with static local IP addresses like 10.0.111.2 and 10.0.111.3, with a VIP in CARP mode set to 10.0.111.1. The primary idea is that the master firewall automatically establishes the PPPoE link when it becomes the master. This part works fine. The problem occurs when I unplug the power cable from the ISP’s dumb switch, and it always results in two mpd daemons running simultaneously.

Urgh, that's in the new 24.08 snapshot?

@stephenw10
Yes.

Hmm, let me try to replicate that...

@stephenw10
Any luck?

stephenw10

Not yet. I'll try to get the config back in place today.

In April/May I gave a pretty precise problem description including a hint on which files probably contained the error. Was this really just for the bin? Is there any better way to address bugs in the paid product than this forum?

stephenw10

You can open a bug report directly: https://redmine.pfsense.org/

At the time there were numerous back end changes going into 24.08 and it was felt that any issues would need to be confirmed as still present after those went in.

Since that does seem to be the case in at least one variant of this issue I'll raise it again and try to replicate it locally.

@w0w Starting with https://forum.netgate.com/post/1162532.

w0w

@pFence
hmm ok…
And you also can replicate this on the latest snapshot?

stephenw10

Be very to know that if you're able to test it.

pFence

@w0w
I do not have an extra machine to test snapshot images. I would be willing to replace my current production software only if a bugfix was to be verified.

@pFence
Did you create redmine bug report already?
