Hi,

As per my last email sent to ipv6@ which I CC'd Sheldon and Philip on, I
have had some headway. Well not really, as this was discussed in a
pissing match on tech@openbsd for around 2-3 weeks. I knew I should have
bothered to read that thread. (http://www.sigmasoft.com/~openbsd/archive/openbsd-tech/200106/msg00206.html) Anyway, In OpenBSD:

It boils down to this paragraph in inet6(4):

Because of the above, OpenBSD does not route IPv4 traffic to
AF_INET6 socket. The particular behavior in RFC2553 is intentionally
omitted for security reasons presented above. If you need to accept
both IPv4 and IPv6 traffic, listen to two sockets.

Please see:

http://www.openbsd.org/cgi-bin/man.cgi?query=inet6&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html

Scroll down to Interaction between IPv4/v6 sockets which explains this.

So what should be done next?
