[26.1.3] PPPoE failed and didn’t recover until rebooted

[abraxxa]

Good morning,
my OPNSense running in a VM on ProxMox logged LCP timeouts, took down the PPP session and failed to recover.

This log entries look suspicious:

[wan] IFACE: Rename interface pppoe0 to pppoe0

[wan_link0] can't remove hook mpd46000-0 from node "[11]:": No such file or directory

[wan_link0] PPPoE: can't connect "[11]:"->"mpd46000-0" and "[8]:"->"left": No such file or directory

After a reboot of the OPNSense it worked again.

Suffered exactly the same running OPNSense on Baremetal this morning as well, BT PPPoe. Needed a reboot to fix.

I have also been having PPPOE connection drops issues. Initially on 25.x (which I then put down as bad migration to new hardware) and today on a clean slate install of 26.1.5.

Connecting to/9 second timeout notices loop until reboot
