At some stage in the last few months something changed with the clients = (I haven't updated the base, but ports have been) and they no longer = seem to accept those messages. (I am guessing somewhat here). I am running rtadvd with an empty configuration, and I get my IPv6 range = by using dhcp6c from my ISP which I connect to via PPPoE using PPP.

Unfortunately I can't find much/any debugging information in the clients = to tell me why they are not working :( I did try a FreeBSD 9.0 box and it similarly didn't work - I had the = following in rc.conf.. ipv6_activate_all_interfaces=3D"YES" ipv6_enable=3D"YES" Any help appreciated, thanks.
