I've configured a PPPoE interface on a TCR100 on firmware 07.02.07. With tcpdump I can see the PADI packet go out, and a PADO comes back. But that's all - the link does not come up, and pppd complains about timing out waiting for a PADO.
Tue Nov 1 21:39:26 2022 daemon.warn pppd: Timeout waiting for PADO packets
Tue Nov 1 21:39:26 2022 daemon.err pppd: Unable to complete PPPoE Discovery
Does anyone have any ideas?
