IPv6rd and DHCP option 212

[FInnishFlash]

Hi.

I'm quite new to pfSense and I'm trying to set up IPv6rd for my ISP named Telia in Finland. I know I have to use DHCP option 212 to get the parameters I need but I need help setting it up. Is there a GUI option to tell DHCP client to request for option 212 or do I need to play around with dhclient config? I found a rather old but promising dhclient example (https://forum.netgate.com/post/330917) that should return the needed parameters but I didn't get that working.

This is the error it returned:

DHCPREQUEST on vmx0 to 255.255.255.255 port 67
DHCPACK from 84.xxx.xxx.xxx
unknown dhcp option value 0x7d
unknown dhcp option value 0xd4
bound to 84.xxx.xxx.xxx -- renewal in 600 seconds.

I am running version 2.4.4-p3 on VMWare virtualized platform.

Please advise. :)
