IPv6 Rules with Gateway not working.

[novel]

my devices (cellphones) every time that connect my network has different ipv6 address. Is there solution to not change this address. I would like to change to static ipv6 ip.

How can I do that?

On IOS go to settings, WLAN, disable "Private Address". Probably very similar for Android.

No way to enforce this on the firewall without configuring the phones as far as I know.

On Android, set the MAC address to "Device" (not "Random").

What you can't disable are privacy extensions. Android (like most systems) generates one SLAAC address based on the MAC address (which makes it essentially static, as long as the prefix doesn't change) and one randomised address. For privacy reasons, only the random address is used for outbound connections.
