====== 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.
===== Requirements =====
  * pfsense 2.3.X

----

===== Setup WAN interface =====
  * Go to ''Interfaces -> WAN ''
  * For ''IPv6 Configuration Type'' select ''DHCP6''
  * Scroll down to ''DHCP6 Client Configuration'' and set the following options:
{{ :dhcp6.png?direct |}}
  * The ''Debug'' option is not necessary, however it helps with debugging

===== Setup LAN interface =====
  * 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''

===== Setup other interfaces =====
  * 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
