I have found a weird KEA DHCP4 Error related to USB for whatever reason :

Code Select Expand

ERROR [kea-dhcp4.dhcp4.0x47d7d405c008] DHCP4_INIT_FAIL failed to initialize Kea server:
configuration error using file '/usr/local/etc/kea/kea-dhcp4.conf':
Error during command processing: Interface usbus0 has no index


ERROR [kea-dhcp4.dhcp4.0x47d7d405c008] DHCP4_CONFIG_LOAD_FAIL configuration error using file:
/usr/local/etc/kea/kea-dhcp4.conf, reason:
Error during command processing: Interface usbus0 has no index

I feel like this device should be excluded somehow but since the GUI does not show anything I am not messing around with it via SSH for now.

The only USB devices this install has every seen are :
- USB Stick for the installation.
- Keyboard used during that installation.

Thought it would be fun to mention something positive once in a while instead of all those issues everyone is having because of various reasons ;)

I was running 25.7.10 for a while now and did not upgrade because of :
- Host Discovery issues.
Now that these are more or less settled when it comes to high CPU and a lot of writes to the database after upgrade it seemed OK to ignore it.
Also the first thing I disabled after the first upgrade to 25.7.11_9 was finished.
- Reports about high CPU LOAD because of PHP totally tripping and spawning a lot of processes in one of the 26.1.x releases I believe.
This did not happen after the first 26.1.2 upgrade as far I could see.
- Python version issues somewhere in the 26.1.2 - 26.1.5 range.
I have really become a hater of this programming language the last couple of years because of weird issues seen in multiple projects like Kodi/DSMR/Mopidy and recently also in OPNsense mainly because the ZenArmor users were having weird issues.
Luckily nothing weird happened and I hope it stays that way! :)

And then there is the whole thing about ISC becoming a plug-in and causing some weird issues for some, but I had already solved that in advance by migrating to KEA while running 25.7.10 to avoid any kind of issues in the future :)

For now I am not migrating any Firewall Rules or migrating from Outbound NAT to Source NAT as long as it's not mandatory/one of them becomes Legacy/EOL so those things will stay they way they are for now.

I am also planning to upgrade to 26.1.6 as soon as it's released because of https://forum.opnsense.org/index.php?topic=51440.0 even tho I have no Port Forwards currently.

[ISC has : Ignore Client UIDs]

I was wondering if the following two function the same way or not :

ISC has : Ignore Client UIDs

By default, the same MAC can get multiple leases if the requests are sent using different UIDs. To avoid this behavior, check this box and client UIDs will be ignored.

KEA has : Match client-id

By default, KEA uses client-identifiers instead of MAC addresses to locate clients, disabling this option changes back to matching on MAC address which is used by most dhcp implementations.

I had the ISC option Enabled so now I have the KEA option Disabled and was wondering if the result is the same :

Ignore Clients sending anything else than their MAC Address when requesting a DHCP Lease ?!



I have tried reading about it in the KEA Documentation on their website, but there was nothing related to this that I could find...

[Could you please move the Static DHCP Mappings section to it's own sub-menu somewhere in a future release ?]

Dear OPNsense Developers,

I would like to hereby ask you for a small improvement which you will hopefully appreciate too :

Could you please move the Static DHCP Mappings section to it's own sub-menu somewhere in a future release ?



What I am basically asking is instead of this :
Services
- ISC DHCPv4
-- <Name of the DHCP Server Scope you are editing>

And then having to scroll down each time to the "DHCP Static Mappings for this interface." section when adding or editing any of them.



Let's make it look like this :
Services
- ISC DHCPv4
-- <Name of the DHCP Server Scope you are editing>
--- DHCP Static Mappings

So you can just stay on that sub-menu webpage while adding or editing any of them.



Currently I feel like I am scrolling too much even when logged in from my PC with 1920x1200 monitors and think that moving the "DHCP Static Mappings" section to a small additional sub-menu would improve things a lot :)



Many thanks in advance & Best wishes for 2026 to everyone!
