pfSense 23.01 bug : Unable to set DUID from DHCPv6 Leases

chase

My pfSense 23.01 DHCPv6 Router mode is set to "Managed".

My objective is to visit "Status / DHCPv6 Leases" to setup a static IPv6 assignment for Plume.com devices so that I can better monitor their communication traffic.

In the "Status / DHCPv6" leases, I find one of the Plume devices there. It has a DUID of 00:03:00:01:60:b4:f7:f0:7e:ca.

I click the "+" button for "Add a static Mapping" which opens a tab to "Services / DHCPv6 Server & RA / WIFI / DHCPv6 Server / Edit Static Mapping"

pfSense already pre-populated DUID field with 00:03:00:01:60:b4:f7:f0:7e:ca. Upon completing the other fields (IPv6 Address, Hostname, Description) and clicking "Save", I get an error "The prefix (upper 64 bits) must be zero. Use the form ::xxxx:xxxx:xxxx:xxxx"

QUESTIONS:

What should be the proper DUID value to enter there?
Why isn't pfSense already applying the mask and conversion of its DUID from "Status / DHCPv6" over to this field?

@chase You don't set DUID but an IP-address. Make a screenshot so that we can see what you did wrong there.

Bob ... okay .. thanks for the push-back here. Upon reflection, I was associating pfSense's error [1] with the DUID entry value rather than the "IPv6" value I supplied -- see the following (altered) examples of IPv6 values I tried:

WRONG: 2602:15:c011:e390::1:3ed8
WRONG: ::e390::1:3ed8
CORRECT: ::e390:0000:0001:3ed8

Now that I'm correctly specifying the correct IPv6 address within the context of my delegated prefix, I'm successfully tracking those Plume.com devices.

My one regret is that I cannot change the subject of this posting to more accurately title it as :

In DHCPv6 static mappings, the error "The prefix ... must be zero" means you have the wrong IPv6 value in there.

NOTES:
[1]"The prefix (upper 64 bits) must be zero. Use the form ::xxxx:xxxx:xxxx:xxxx"

@chase My wording isn't the best, glad you figured it out.
