dhcp6c: Unsupported authentication protocol: 100



  • Hi,

    I can't get the IPv6 prefix delegation working with pfSense.
    I've tried a OpenWrt box and its dhcp6 client picked the IPv6 prefix without any problem. Can it be an unsupported feature by pfSense's client?

    This is an screenshot of the log:
