Is it a bug?

[Antibiotic]

I just installed fresh copy of pfSense plus 26.03 and disabled all setting regarding ipv6 protocol. The problem that option to disable DCHP6 server is missing in settings. I can only stop thiss erver from main dashboard but not to disable completely! Its a KEA DCHP6 server. Disabled all but he is still running?)))

Does this persist across a reboot? Let me try to replicate...

@stephenw10 Yes , after rebooting the same situation)))

Hmm, I can't replicate that here. As soon as I disabled the last dhcpv6 instance the service is removed from the list.
The config change shows:

@stephenw10 Do you need any configs from my sides?If yes, get me commands to paste here!

[stephenw10]

Oh I see you have set the LAN to something that cannot have a dhcpv6 server set so the tab is hidden but the service is still enabled there. Somehow.

If you set the LAN IPv6 type to static with an address then you will be able to disable the service then set LAN as none again.
