How can I disable IPv6 or use temporary addresses. Regular methods don't work. [SOLVED]

After hours, literally *hours*, researching this IPv6 crud I think I have it.

Apparently Network Manager overrides the regular IPv6 settings configured in `/etc/sysctl.conf`.

So its a two part fix.

 

First setting `method` to `ignore` is part of the solution (see sfx2000's screenshot)

That takes IPv6 out of Network Manager's control.
BUT `nmtui` wouldn't let me save that setting... I've no idea why.
So I had to do it manually

    sudo nano /etc/NetworkManager/system-connections/eth0
    ---[snip]---
    
    [IPv6]
    method=ignore

 

Then all the regular `/etc/sysctl.conf` changes seem to work.
I've tested Privacy extensions and disabling IPv6.


Hope this saves someone else wasting hours of their life they'll never get back :rolleyes:

Thanks, sfx2000.  But I'd already "disabled" IPv6 using that method.
On my first Armbian setup attempts, no matter what I did, my system never got an IPv4 address.
It only ever had an IPv6 (despite my network being IPv4.)
Eventually I stumbled on that `armbian-config` option.

Once "disabled" it allowed the system to get an IPv4.  But despite what it says, it didn't "disable" IPv6 system wide.
Tools like `ip addr` and `ifconfig` showed it still had IPv6 active.
