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.
