Getting UGAs via Router in front of pfsense / IPv6 network delegation

Rooter

Hi everybody,

I'm not getting it. It's usually quite simple but pfsense doesn't make sense to me. :D

I have a proper router cascade with 2 Fritz.boxes. the second box is getting an prefix from the first one and spread the UGAs as supposed to be.
But I have no idea whats going on with pfsense.

heres an overview:

working:

Fritz.Box 01 prefix ::/56 -> Fritz.Box 02 prefix ::/62 -> UGAs on Clients at the LAN side

not working:

Fritz.Box 01 prefix ::/56 -> PFSense -> no UGAs on Clients at the LAN side

I put an IPv6 static adress on the LAN side Network but still no prefix available.
There are some Options but I ticked them and nothing happens. I'm not really sure.They shouldn't useful anyway because it's looking like Delegation.

Can anyone Help me with that?
It should be simple but I can't find a way to get it running. :(

If you want pfSense to pick up and use a delegated prefix then:

WAN must be set to DHCPv6
You must have the proper delegation size filled in on the WAN settings.
LAN must be set to track6 with the WAN chosen
LAN must have a delegation prefix set (typically 0)

And in addition to jimp; in FB you specify the prefix-size which you then use with pfSense.

For FB config "Require certain length for the LAN prefix": let's set : 64
Then pfSense WAN: "DHCPv6 Prefix Delegation size" : 64; "Send IPv6 prefix hint" : true

And reboot the pfSense, FB, or both in logical sequence.

Hey guys,

Thanks for your help.
I did exactly what you described but hdas Addition was the missing Piece and got me on track.

It is now working as I thought it has to be and similiar to my second Fritz.box.
I'm playing around a bit and will come back if I have more questions.

Thanks again. :D
