PPPoE over 802.11? Not working!

[Mattias Baath <mattias.baath@home.se>]

Happy new year everybody.

I've been using the Lucent WaveLan(Orinoco) adapter for a few weeks to my
ISP... great flexibility and easy to install.
Really nice.. and ofcourse I use an OpenBSD2.8 for router/firewall etc. not
a too uncommon thing I take it.

The problem appears now that our ISP wants us to use PPPoE over this WaveLan
connection...
After alot of configuring I am certain that I've set it all up straight and
still it don't work.
I did bounce a mail to Jason Wright and he too said this should work fine,
even 802.11 isn't really ethernet.

The problem is really shallow, I can see the PPPoE-Discover (PADI) being
sent to the adapter (tcpdump locally I see the packet) but listening to the
net using another adapter, or even tcpdumping at the BaseStation, it never
turns up.

So the problem is probably not in PPPoE but with the "if_wi" driver... I did
recompile the kernel with "WIDEBUG" but that don't really give me anything.

I am not sure I should report this as a bug or as lack of feature. I know
that the windows clients our ISP provides works fine. They also claim to
support Linux clients so I suppose their WI implementation is different...

I would appreciate any help I can get since I don't wanna use anything but
OpenBSD as the firewall... it would also be really uncomfortable leaving the
NAT to a separate windows box. :(

--- On the tech side I can say the following: ---
The PPPoE-Discover packet follows the RFC nicely and the source MAC address
of the packet I try to send is that of the correct card.
If I change nothing but the interface name (-i <if>) that I pass to "pppoe"
I can see the packet being sent on a regular wired ethernet adapter.
This should be fairly easy to reproduce if you own a WaveLan
(www.wavelan.com) card.

Please help.
