Can you please confirm that there're no firewall rules on your FreeBSD host blocking the NS messages? You can disable IPFW / PF / IPF and reboot to get= a clean environment. Check PF: # pfctl -s Running For IPFW: # ipfw show And also check statistics for ICMP6: # netstat -sp icmp6 --=20 You are receiving this mail because: You are the assignee for the bug.=
