Brian (and other -net PPP experts),
We are trying to test our PPP over Ethernet (over DSL) driver
on Windows2000, talking to a FreeBSD (4.0) machine running pppoed.
The PPPoE part itself is working fine. Basically, our driver
does the PPPoE negotiation, and then we tie into the Microsoft
PPP stack. This setup works fine on Win98, but when we tried
Win2000, we aren't able to establish a PPP session.
We're set to use a fixed IP address, and the IP address negotiation
sort of works, but then pppoed keeps trying to get us to use an
address of 0.0.0.0, which keeps getting rejected by our side,
and eventually it gives up and terminates the PPP session.
I got a debug log on our client, and decoded (by hand) the
PPP session (after the LCP phase) to see this exchange:
(this is viewed from the client end)

Since we can't "fix" Windows 2000 PPP code, is there something
that the FreeBSD PPP is getting "confused" about due to the
Win2000 implementation that can be fixed?
Thanks,
Gary
