I have my Vigor 130 configured in bridge mode and perform PPPoE from a Linux machine.
When running Firmware version v130_3793_modem_STD on the Vigor 130 everything works as expected.
I tried updating the firmware to v130_3812_modem_STD with no changes in the modem configuration and no changes in Linux configuration and unfortunately it stops working
From the log on the Linux machine I see a whole heap errors before pppd eventually gives up. Unfortunately nothing in the firmware Release Notes points at what changes I might need to make in the configurations to get it working.
