      Hello,

      My ISP propose an IPv4 and IPv6 (/56) dual-stack. The connexion is established by pfSense in PPPoE (on my WAN interface) to my ISP.

      I receive my IPv6 configuration via my FAI in DHCP6.

      I would like to link the computers which are connected to my LAN to IPv6 websites.
      I configured my LAN interface in "Track Interface IPv6" to the WAN interface.

      Here is my problem : from pfSense I can ping some IPv6 websites but it isn't possible from my LAN. The global IPv6 adress is attributed to the lo0 loopback interface and not to my LAN interface.

      However sometimes the LAN interface receive this global IPv6 adress and it works! Unfortunately it's unfrequent. If it works, I reboot pfSense and then the global adress can't reach the LAN interface anymore.

      In the log, I have some abnormal items :

      Dec 28 15:12:26	php: rc.resolv_conf_generate: The command '/sbin/route change -host -inet6 2a00:xxxx:xxxx:c05::66 fe80::230:88ff:fe04:67e7' returned exit code '1', the output was 'route: writing to routing socket: No such process route: writing to routing socket: Network is unreachable change host 2a00:xxxx:xxxx:c05::66: gateway fe80::230:88ff:fe04:67e7: Network is unreachable'

      My configuration :

      My problem seems similar to this one https://forum.pfsense.org/index.php?topic=70791.15

      The few times and it worked on my LAN, the routable table looked like this:

      But it happens once in ten … :-(

      Could you help me?

      Thanks a lot :--)

        Since this morning the LAN interface had no public IPv6 address, and now I returning on pfSense and the LAN interface has received its IPv6 address ..
        Why must wait several hours before the interface obtains its IPv6 address?

        Now :

        But if I reboot pfSense now I know I should not have IPv6 address on my LAN interface for some hours…
