Help with DHCPv6-PD



  • Hey there!

    At last, IPv6 is available from my ISP. They have informed me to use DHCPv6 and Prefix Delegation and a /60 network. (No SLAAC)
    My WAN-interface is configured with DHCPv6 and prefix delegation size set to 60.
    WAN-interface receives a public IPv6 address with /128 prefix. (2a02:fe0:cf00…...)
    I have also enabled DHCPv6 and PD with size set to 60 on my LAN interface, but i get no IPv6-addresses on the inside or the pfSense-interface.

    Any tips? Never fiddled around with prefix delegation before.

    Running 2.1-BETA0, July 5.

    Thanks!



  • you set the wan to dhcp-pd prefix size 60

    You set the lan to track interface wan. That should be enough.



  • I tried to enable track interface on a couple of my LAN-interfaces.
    What happens, is that both interfaces get the same link local address, fe80::1:1 (loopback ip?)
    Even when i disable IPv6 on both these interfaces, fe80::1:1 is still the active link local address.

    I have two physical interfaces, one for WAN and one where all my LAN interfaces are VLAN-tagged. All LAN and OPT-interfaces are renamed.

    The log also outputs this when i track the WAN-interface:
