htp.net IPv6 Prefix Delegation on pfSense

My ISP is htp.net which give me IPv4/6 Dual Stack. Here is how to configure prefix delegation for IPv6. htp.net gives customers a /56 prefix.

  • pfsense 2.3.X

  • Go to Interfaces → WAN
  • For IPv6 Configuration Type select DHCP6
  • Scroll down to DHCP6 Client Configuration and set the following options:

  • The Debug option is not necessary, however it helps with debugging
  • Go to Interfaces → LAN
  • For IPv6 Configuration Type select Track Interface
  • Scroll down to DHCP6 Client Configuration and set the following options:
    • IPv6 Interface: WAN
    • IPv6 Prefix ID: 0
  • Just repeat the LAN interface step up to 254 more times
  • Increase the IPv6 Prefix ID everytime, so LAN gets 0, OPT1 gets 1, etc…
  • The prefix ID is in hexadecimal, so write a instead if 10
  • The IDs do not have to be consecutive, you can choose them however you want, as long as they are between 0 and ff
