upgrading to 25.07, if_pppoe and new bug or what?
-
Okay, finally! Updated to 25.07 - everything looks normal. Switched to using if_pppoe. Nothing fell off, etc. But in the system log I see a lot of spam "pppoe: alien host unique tag, no session found". What is this and how to overcome it? Do I understand correctly that I need to specify some value in PPPoE Configuration - Service name or not?
-
Nope, I would normally only expect to see that whilst the session is establishing or shortly after it disconnects.
Is the PPPoE link up and passing traffic as expected?
Is this new behaviour since the beta/RC? Or is this the first time you've used the new if_pppoe?
-
Yes, the traffic is normal, without losses. And everything is fine in general. This started right after the upgrade to 25.07. Before that, on the same configuration, this was not observed.

@Cyber100 said in upgrading to 25.07, if_pppoe and new bug or what?:
Before that, on the same configuration, this was not observed.
But to be clear that was in 24.11?
-
@stephenw10 yep, in 24.11
-
Ok and you're seeing that continuously? Not just after a reboot or re-connection?
-
@stephenw10 Rebooted twice, log entries continue to appear every two to three seconds.

Can you show the output from:
pppcfg pppoe0 -
@stephenw10 dev: igb1 state: session
sid: 0x47fb PADI retries: 1 PADR retries: 0 time: 10:12:30
sppp: phase network authproto auto authname "MYUSERNAMEHERE" peerproto auto
dns: dns1 dns2 -
Hmm, seeing that error implies pfSense is seeing pppoe packets from different session on the interface. Normally that would only ever happen immediately after boot or reconnecting when the server side still has an old session active. But it should time out shortly after that. If you're seeing them continue something else is happening.
We might need a packet capture to see what's happening there. -
@stephenw10 Yes, I also assumed that it might not be a closed old session on the provider side. I will monitor for some time. Thank you.
