nmap 4.11 + OpenBSD Kernel PPPOE = strange error

[Rembrandt <rembrandt () jpberlin de>]

Hello everybody,

I got a new (faster) DSL line so I switched from userland pppoe to
kernel pppoe (using OpenBSD 3.9 STABLE).

I noticed that nmap has a strange Bug (well I suspect nmap is the
source of evil here) :)


At first I tried to do a SYN-Scan and after that I simple used a
3-Way-handshake.
There`s NO Firewall blocking anything and I connected this Box directly
to the Internet (so no Router either).

godfather $ ^D

I never had any problems as I used userland PPPoE but also just nmap
has Problems with the Kernel PPPoE.

Any solutions for this?
I asked (mailed) already the OpenBSD Port-Maintainer but I got no reply.


Kind regards,
Rembrandt
