PPPoE Issue

[andyh]

Hi everyone,

I'm new to OPNsense and trying to configure a PPPoE connection on my instance. The modem is a standard ISP Zyxel router configured in bridge mode. I have no problems connecting over PPPoE with either Fortigate or Sophos XG devices, but OPNsense is unable to do so.

From the logs below I can see that my user credentials are being accepted, that an IP is being assigned (my static IP) and that the assigned gateway IP is correct. However, following that, the link drops and goes into an endless re-connect loop.

Having read a lot of forum posts, I have tried the following, but nothing has been successful:
- Using a switch inbetween OPNsense and the modem.
- Forcing the MTU to 1492.
- Configuring the interface MAC to match a device that will connect.
- Rebooting the device to check connection immediately after reboot.

I'll also add that my ISP are a relatively small regional company in the UK and tend to do things slightly differently to the major players.

My OPNsense box is a ESXi VM, with passed through interfaces. Version is OPNsense 22.1.2_2-amd64

If someone could point me in the right direction to resolve this I'd appreciate it. The logs below were taken immediately after reboot.
