I have not progress with solving my issue. So far I found that with setting= s: ifconfig gif0 inet6 no_radr ifconfig awg0 inet6 no_radr and sysctls: net.inet6.ip6.accept_rtadv=3D0 net.inet6.ip6.no_radr=3D1 the default route still gets overwritten with 2001:470:1:c84::16, 2001:470:1:c84::28 or 2001:470:1:c84::29. I will check if filtering icmp6 on gif(4) helps and maybe will turn this of= f to check if incoming RAs from gif(4) are really the culprit. --=20 You are receiving this mail because: You are on the CC list for the bug.=
