Title: PPoE stability issues since the last patch
Post by: Riem on January 28, 2026, 04:19:15 PM
hello all,
Just updated to the latest release and I'm having a bit of a nightmare with my WAN stability. I expected a smooth reboot, but now my PPoE connection keeps dropping every twenty minutes or so for no clear reason. The BT Openreach modem seems fine, but OPNsense just refuses to hold the lease, which never happened on the previous version. I've had a go at toggling the MSS clamping and checking the logs, but nothing obvious is jumping out at me. I'm no networking wizard, so I'm wondering if a default setting has shifted in the background. Is anyone else on UK fibre seeing these drops, or have I just got a dodgy config somewhere?

Please start with the last known good version and the first bad version and show us a system log snipped of what you're taking about.


Thanks,
Franco
