PPPOE interface down after upgrade to 22.7.4

[thijs]

Hi all,

This week we upgraded two older OPNSense firewalls (the white boxes) at different locations from a version 22.1.x to 22.7.4. Both firewalls are connected to WAN with PPPOE (no VLAN). They both stopped connecting to the internet after the upgrade, the physical interface doesn't even show any sign of connectivity as no LEDs are lid while there is a network cable connected to it.

We were able to get it working again on one of the firewalls by creating a new PPPOE-interface on a different physical interface but then we also needed to change all the firewall rules. That was doable at the first site, but not at the second one. Luckily the second site is still online as it has two firewalls in a HA scenario and I didn't update the active one.

In the update notes I saw one line about PPPOE: "interfaces: refactor DHCP and PPPoE scripts to use ifctl exclusively". Does this corrupt our config/interface? And if so, where do I find the config files or log files to fix this? The logging under "Interfaces > Point-to-Point > Log File" isn't of much help.
