Hi,
I'm trying to replace a PC Engines Alix board with an APU 2c4 board,
but I'm having some issues to get it up and running.
I have a fiber connection and my ISP requires a PPPoE connection over
VLAN 6.
With the old setup, this works like a charm.
With the new setup, I can't get the PPPoE connection to work.
When I use tcpdump on the ethernet interface, I can see the PADI
packets leave the system on VLAN6, but there is no answer at all.
OpenBSD keeps sending a PADI every minute or so, to no avail.
I have tried to get it running with 5.9-stable (amd64), with a recent
snapshot (amd64), with 5.9-stable (i386, as that works fine on the
Alix), but none of them work.
When I have a working connection on the old router and then quickly
move the cable (the one that is connected to the fiber/copper
converter) to the new router, I can see some packets (belonging to the
'old' PPPoE connection) arriving on the new router (with tcpdump).
So at the ethernet level the link is OK.
Does anyone have a clue what could be causing this? Some VLAN-tagging
issue with the I210 NIC on the APU? Does anyone have a similar setup
working?
Thanks a lot in advance,
Maurice
Thanks for the help. It appeared to be a subtle issue at the ethernet
link layer, so nothing to do with the software configuration.
For the record: there was an ethernet link between the fiber/copper
converter and the router (with about 15 m of cat 5e cable in between
them), but no data was getting through. When I add a switch next to the
converter (and the same 15 m of cable between switch and router), it all
works again.
Sorry to waste your time on something that has nothing to do with OpenBSD.
