This is a python script to setup connection sharing from your internet-facing interface to a USB/RNDIS Device. This was originally made to be used on Debain 12 and a WiFi Pineapple but this can be used on other devices as well.
You may need to install the iptables package. On Debian or debian based distros(ubuntu, kali, etc), you can run
sudo apt install -y iptablesAs this modifies IP Tables, this will need to be run as sudo/root.
