Now the problem is how I make this permanent accross reboot

 

Normally I don't recommend this, because people tend to forget this in the future, but you can add the disable line in the 'go' file on your USB device.

Put the line before starting the GUI (emhttp).

Would be good when someone select ipv4 only to really disable it everywhere like in all.

 

The all setting is not used because you should enable or disable IPv6 per individual interface, it is allowed to mix between ipv4 and ipv6 depending on requirements

That's great, I put that in the go file and so far so good. Thank you!

Sharing a thank you for running this down, saved me lots of time.
