Im running /usr/ports/net/sixxs-aiccu to bring up the tunnel and my adresses are assigned from them. www.sixxs.net for more information. The tunnel works all the time (on the tun0 interface) so there isn't a problem with my ipv6 connectivity. So i guess my question is: "Why is net.inet6.ip6.accept_rtadv=0 in /etc/rc.d/network_ipv6 and how am i supposed to configure ipv6 in /etc/rc.conf?" PS: sixxs-aiccu is run from /usr/local/etc/rc.d/ so the reason things doesn't work could be related to the fact that my tunnel goes live late in the boot. /Chris -- http://www.arnold.se/
