IPV6 passthrough rules - MikroTik
https://forum.mikrotik.com/viewtopic.php?p=72493507.04.2019 · I have both the providers router and this other network within, where a Windows machine get's ipv6 traffic passed through without any problems. I replace it with my new fully updated to 6.44.1 Mikrotik RB4011 router with ipv6 enabled and unfortunately nothing is passed through it doesn't get an ipv6 address at all.
