Thanks again.

I managed quite easily with just adding an external USB WIFI (RTL8188CUS) dongle, reboot and issuing:

ip link set wlan0 down
iptables -A FORWARD -i tether -o eth0 -j DROP

That should meet my requirements. (Or do I miss something?)

Thank you.

And if want use to use an USB WIFI adapter (which I can put on a USB extension cable to get a bit better coverage) instead of the built-in one.

Is that possible?

LibreElec 10.0.1 RPI4.

Very happy with it.

How do I disable internet access on a tethered Wifi AP?

I tried

echo 0 > /proc/sys/net/ipv4/ip_forward

but that also disables internet for docker containers.

Can I configure this with connmanctl, or is it a iptables setting?
