    Is it possible to use CARP/HA with IPv6 DHCP on WAN?

      I now have a home setup of two pfSense boxes with pfSense 2.8 beta. I get a /48 subnet from the ISP on just one of the pfSense boxes. For IPv4 i do get a public dhcp address on both pfSense boxes, but I do not get two /48 subnets for IPv6 (only one for each customer). Would it be possible through some clever way to delegate an IPv6 address from the /64 subnet used for WAN on the primary pfSense box to the secondary pfSense box?
      I can do it manually, and that would work, but if I at some time are given a new IPv6 subnet this would stop working and possibly cause trouble for others given my old IP adddress. I guess this is not a conventional use of the pfSense firewall and would probably need some scripting to solve.
      Have anyone else done this to save money since dhcp is usually much cheaper than static IP. For me static IP is not an option, since that mean registering a business broadband connection from my ISP. Actually some ISP's offer static IP to private customers, but currently this is not the case where I live.
