For sho= rt, the OVH guides are broken. They works on Linux but not on FreeBSD 11 and FreeBSD 12. A workaround to fix it. Register a static NDP entry, # ndp -n -s IPV6_GATEWAY GATEWAY_LINKLAYER_ADDRESS to make it permanent, # sysrc static_ndp_pairs=3Dgw # sysrc static_ndp_gw=3D"IPV6_GATEWAY GATEWAY_LINKLAYER_ADDRESS" CC Andrey V. Elsukov to review this workaround. --=20 You are receiving this mail because: You are the assignee for the bug.=
