Your command is my command:
cerebus:~# tcpdump -nev -s 256 -i de0 ether proto 0x8863 or ether proto 0x8864
tcpdump: listening on de0

I think I may have an idea. You are sending a Host-Uniq tag in the PADI. I
have this funny feeling that my ISP doesnt like that. I'm in the middle of
running some tests to see what happens when I change pppoe_start() to not
insert that tag in the PADI.
(Yes. I know that this might break some things, but I want to see if my ISP
actually emits a PADO in response to the modified PADI)

You know, I havent a clue. I'm currently not set up to sniff the windows
client when it operating.

I know. However, based on some code I had written before, my ISP responds
quite happily to a PADI containing a NULL Service-Name. Rumor has it, that my
ISP (Sympatico in Canada) isn't quite on the ball when it comes to a compliant
PPPoE implementation.
I'll let you know what I find out. Presuming that Sympatico continues to barf
on the Host-Uniq tag, are there any workarounds?
