iPad weird behaviour

Hi all, i’ve setup a vpn with a rpi5 as ZeroTier bridge.
Everything work flawlessly but if I try to get into the vpn from my home network, which is under cgnat, with my iPad, although I see it is connected in ZT central, i don’t see any other client of the vpn. It is “de-facto” disconnected.
With my Android phone and win11c on the same cgnat network everything is fine.

If I enable the hotspot on my mobile i can Connect with the iPad with no issues.

I tried also with another ipad and it behave the same way.
Any hint?

Found what the issue was.
For some reasons, the IPAD IP address was into the DHCP address pool of my home network. Changed the IP and everything is fine. Sorry for clutter
