If proto 'dhcpv6' is set for an interface, dynamic interfaces are created for the protocols map, dslite or 464xlat if this netifd protocols are installed and the interface option is not explicitly set to '0'. The problem is that this option cannot be configured via LuCI, which means that the dynamic protocols are started. In my case, that is the '464xlat' '6in4' protocol. I see the follwing log messages continuously in the log as I do not have a '464xlat' in my network. Fri Aug 22 10:36:33 2025 daemon.notice netifd: Interface 'wan6_4' is now down Fri Aug 22 10:36:33 2025 daemon.notice netifd: Interface 'wan6_4' is setting up now Fri Aug 22 10:36:36 2025 daemon.notice netifd: Interface 'wan6_4' is now down Fri Aug 22 10:36:36 2025 daemon.notice netifd: Interface 'wan6_4' is setting up now To fix this by adding a new option to disable the dynamic interface creation for '4in6' if needed. The option is named '4in6_dynamic' and is a boolean. If the new option is 'true' (default) dynamic interfaces are create. If the new option set to 'false' no dynamic 4in6 interface are created.
