25.03 BETA - PPPoE WAN Reconnection

ajtuk

We pay for TAC Pro, but they won't help with issues when you are running the BETA releases apparently.

We have a UK FTTP connection over PPPoE. We are using the if_pppoe backend. If our ISP (Andrews & Arnold) drops our connection, the PPPoE link won't reconnect until we either reboot the appliance, or, click Connect WAN under Status, Interfaces.

The new if_pppoe doesn't seem to contain the Dial On Demand options that used to be available.

Are we missing something obvious in our config?

Log file doesn't have much to go on. The link is trying to come up, but it's never successful.

Does it reconnect as expected using the old mpd5/netgraph?

Is it failing at both IPv4 and IPv6?

If you disable IPv6 does it then reconnect correctly?

We have seen one other report from an A&A user but that failed to connect after reboot.

@ajtuk Hi, yeah you might need the bug fix for ip aliases, if you have one added to your pppoe. Stephenw10 linked me to the patch in my thread.

The patch is here, this totally stabilised my PPP session.

Also I think AAISP cycle the pppoe after its established which I think is why I had to add a delay to get IPv6 working. (although this delay for some reason isnt needed on legacy pppoe).

You see that in the logs?

@stephenw10 dont think so, I got this from their wiki page which mentions they might do PPP negotiation a second time to solve some MRU issues.

If I watch the firewall, it comes up fairly quickly. So I am not sure if this is whats going on with AAISP, just something I read on their wiki page.

Actually I do see duplicate log entries, which does suggest maybe it cycles twice.

Ah, interesting. Maybe I should just move to A&A to be sure.

Thank you. We updated to 25.07-RC. Is that patch included in that version?

stephenw10

Yes, it's in the RC.
