      Hello,

      I actually have:
      PFSense 2.1-DEVELOPMENT (i386)
      built on Fri Nov 25 14:30:42 EST 2011
      FreeBSD 8.1-RELEASE-p6

      and I was trying the new 2.1 RC0 build:

      2.1-RC0 (i386)
      built on Sat Jun 8 06:42:11 EDT 2013
      FreeBSD 8.3-RELEASE-p8

      When configuring WAN/LAN for the settings required by my ISP (which offers IPv4 and IPv6 via PPPoE and DHCPv6-PD ((RFC 3769) I found the following changed from DEV to RC0 and was wondering how can I configure PFSense to achieve the same results I now have on 2.1DEV.

      Settings on 2.1 DEV:

      Settings on 2.1 RC0:

      Observe the missing DHCPv6 Unique Identifier (DUID) from the WAN settings on the RC0 build.

      On the LAN side, it gets even more different:

      Settings on 2.1 DEV:

      Settings on 2.1 RC0:

      Please note the missing DHCPv6 Prefix Delegation ID <id>This ID sets the delegated DHCP-PD prefix number which will be used to setup the interface.

      Is there any other way to configure this ?

      I've managed to make the connection work also with a cisco 881, but would still want to use PFSense.

      If it helps, here is the config on the cisco:

      ipv6 unicast-routing
      ipv6 cef
      !
      vpdn enable
      !
      vpdn-group pppoe

      WAN Interface

      interface FastEthernet4
      no ip address
      ipv6 nd ra suppress
      duplex auto
      speed auto
      pppoe-client dial-pool-number 1 service-name "ipv6test"
      no cdp enable
      !
      interface Dialer1
      mtu 1492
      ip address negotiated
      encapsulation ppp
      dialer pool 1
      ipv6 address dhcp
      ipv6 dhcp client pd DH-PREFIX # here we set the prefix
      ppp pap sent-username <user>password 7 <pass># my PPPoE user/pass
      no cdp enable

      interfata LAN

      interface Vlan1
      ip address 192.168.1.1 255.255.255.0
      ip tcp adjust-mss 1452
      ipv6 address DH-PREFIX 0:0:0:1::/64 eui-64 # ISP Offers /64

      Any help would be greatly appreciated.

      Thanks.</pass></user></id>

        On the LAN side, you have to set the "IPv6 Configuration Type" field to "track interface" for DHCP-PD. This will give you fields to select which interface to track (WAN), and which prefid ID to use.

          That said, there are still some issues being sorted out with DHCP-PD; see this thread in the 2.1 snapshot section.
