https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263288 --- Comment #7 from Zhenlei Huang <zlei.huang@gmail.com> --- It looks like the upstream router's neighbor cache entry expired and then it issued Neighbor Solicitation messages but the host ignored them. 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.=
