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. The capture is taken during the startup of the FreeBSD system. I would like to know where the address ff02::2:2d75:f2b8 comes from. ------------------------------------------------------- ifconfig -mL plip0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> metric 0 mtu
