ipv6 from LAN is working - dhcpv6 working / static ipv6 assigned is working
ipv6 from SRV is not working - dhcpv6 not working / static ipv6 assigned not working
ipv6 from SRV work if i set interface autothere is only one linux server connected to srv

it was working before but the other day there was a long outage and the server/pfsense shout down
ipv6 from tunnel broker hurricane
ipv4 is working
any help would be really appreciated -
after losing 2 days of sleep
the problem was solved after disabling "Block private networks and loopback addresses" and/or "Block bogon networks" that i had on the WAN interface
it was mentioned here
https://redmine.pfsense.org/issues/9631
also a route come out of nowhere after cheking the routing table i had the ip from general settings / DNS inside the routing table
