DUID issues

ababo

Hi,

My ISP requires that I give them my DUID so they can assign me a fixed IPv6 /56 range.
This is my config :
Interfaces/WAN
IPv6 Configuration Type : DHCP6
DHCPv6 Prefix Delegation Size : 56
Start DHCP6 client in debug mode
All other settings are disabled.

Interfaces/LAN
IPv6 Configuration Type : Track Interface
IPv6 Interface : WAN
IPv6 Prefix ID : 0

System/Advanced/Networking
At DHCP6 DUID I checked the Raw DUID and copied that. In the DHCP logs I also see the same DUID. After I click on Save the DHCP6 DUID selection automatically returns to DUID-LLT.

The DUID I gave to my ISP is 00:01:00:01:24:ae:6b:5b:40:62:31:08:98:40

In the DHCP logs I see the following:
Jul 2 21:38:52 firewall dhcp6c[25266]: get DHCP option client ID, len 14
Jul 2 21:38:52 firewall dhcp6c[25266]: DUID: 00:01:00:01:24:ae:6b:5b:40:62:31:08:98:40

Jul 2 21:38:52 firewall dhcp6c[25266]: IA_PD: ID=0, T1=0, T2=0
Jul 2 21:38:52 firewall dhcp6c[25266]: get DHCP option status code, len 43
Jul 2 21:38:52 firewall dhcp6c[25266]: status code: no prefixes
Jul 2 21:38:52 firewall dhcp6c[25266]: get DHCP option DNS, len 32
Jul 2 21:38:52 firewall dhcp6c[25266]: get DHCP option domain search list, len 12
Jul 2 21:38:52 firewall dhcp6c[25266]: get DHCP option NTP server, len 48

I don't get a Prefix Delegation and no IPv6 is assigned to my LAN.

Now when I change the DUID on my PFSense to something else, last hex number to 50 instead of 40, but I don't change the setting at my ISP, I get the following in the log

Jul 2 21:39:35 firewall dhcp6c[37622]: get DHCP option client ID, len 14
Jul 2 21:39:35 firewall dhcp6c[37622]: DUID: 00:01:00:01:24:ae:6b:5b:40:62:31:08:98:50

Jul 2 21:39:35 firewall dhcp6c[37622]: get DHCP option NTP server, len 48

Here I get a /56 Prefix Delegation and my LAN interface get a IPv6 address.

At the moment I have an Edgerouter and there IPv6 is working perfectly. If I give the DUID of that to my ISP I get the correct /56 and PD is working correctly.

Does anyone have any idea for a solution?

It's OK now. I left it alone for a few days, because I was to busy doing other things. And I just checked and I get the fixed prefix now.
