New PPPoE backend, some feedback
-
The 171.diff patch really improves things. New text file with logs, dmesg -a and my remaining comments sent direct.

Hmm, I can't replicate that FQDN access issue. How does it fail when you do that?
-
The GUI stalls and I get this:
With the fqdn it's like as soon as the WAN is lost it forgets that local access is still available. Perhaps unbound is restarting and local look-ups are dropped but I'm not really sure of the cause. I'm not using Kea, if that is a factor.
If I use the GUI via the IP address instead and take the PPPoE interface down / up then the GUI stays alive.

Hmm, yeah that does seem like it must be an Unbound issue. I guess I'm not seeing it here because I'm not using that box for DNS...
-
Just a reference: There is another thread where a user reports an issue with connecting to the webGUI (503 error) after upgrading from 24.11 to 25.03-BETA and then switching on the if_pppoe module:

This may be a manifestation of the same bug: https://forum.netgate.com/topic/197119/dns-resolver-exiting-when-loading-pfblocker-25-03-b-20250409-2208. Some ISPs send RA packets too aggressively, and due to a bug, pfSense starts endlessly restarting related services and daemons. On certain hardware, it's even possible that PHP hangs as a result. -
Yup I'd bet it's that ^. Should be fixed in the next beta build.

This may be a manifestation of the same bug: Some ISPs send RA packets too aggressively...Thankfully my ISP is very mild with the RAs (and complies with the standards), so it is very rare for the process to be triggered by an RA and is almost exclusively an RS from pfSense kicking it all off.
The dns-resolver loosing its mind when pfBlocker does its thing would probably explain why the fqdn gets tossed.
Whilst it doesn't solve everything the 171.diff experimental patch has really calmed things down on boot & interface status change. Looking forward to all this being collected in a new beta. This is all looking positive.

Here's the file to test. This is not the final fix that will be in the build though.

Oh yes, I tested an earlier version too, but this one at least works with the latest snapshot.
It looks promising.

I'm not sure if my buffer bloat on 23.05 / PPPoE is truly related to all this so I have opened a different thread here.
