Running Ubuntu 20.04 on a Pi with netplan disabled and using NetworkManager only.
Have wlan0 running in AP mode and an ethernet cable connected to the Pi.
I want connections made to the wifi AP on wlan0 to be able to access the internet.
I believe this would be accomplished by forwarding traffic between wlan0 and eth0.
I’ve tried using iptables as mentioned in many other answers, but I can’t seem to get it to work.
This didn’t work: iptables forwarding between two interface
Is there a strictly NetworkManager way to do this?
