I've modified the kernel PF implementation to pass IPv6 fragments.
The first fragment
Hi!
I'm using FreeBSD 8.3 which doesn't support IPv6 fragments in PF.
Does FreeBSD 9.x PF support IPv6 fragments?
I can't find it in the 9.0 or 9.1 manpages. For pf.conf they are the same as in
FreeBSD 8.3.

No, the embedded scope is an internal value. Why should it be set manually?
It's correct handled in the checksum calculation part where the scope is
cleared.
But you are right. The dropping of th

Hi!
Thanks! It works fine. I've tried it for FreeBSD 8.1.
It would be nice to change it in FreeBSD 9.0 and 8.3! ;-)
Bye, Rainer.

Hi!
The output of netstat is fixed but what about the route command?
I would like to add or delete a route like "ff01::%fxp1/32" manually.
The route command complains: "hostname nor servname provided, or not known"
when I use the "%interface" notation.

HI!
FreeBSD 8 uses a strange notation for multicast routes with interface local
scope something like:
ff01:3::/32
Here '3' is the scope id of the interface.
OpenBSD uses the same notation as proposed in RFC 4007 for link local scompe
multicast addresses:
ff01::%fxp1:/32
Why does FreeBSD use a
Node Information Query: FF02:0:0:0:0:2:FF00::/104.
Where is the 2:FF in my address??
ff02::2:2d75:f2b8

Yes I can ping this address from another node and its link local address.

Yes! It's the FreeBSD 8.2 release. The only thing which is activated in the
rc.conf is ipv6.
I've included the ifconfig output and a wireshark capture.

Hi!
The FreeBSD 8.2 sends sevaral MLDv2 listener reports during startup.
The system sends one listener report with its solicited multicast address which
comes from the automatically generated link local address.
But I can see another MLD2 listener report with 2 records. One is the mentioned
