I know there is an option to share internet in the node settings and I understand this is not something I would want to leave on by default (maybe just an opinion.) However while I been looking to set up a secondary location for a node (right now is testing my mini network in my house) I was wondering what would happen if multiple nodes shared the internet at the same time? How do larger nodes and tunnels prevent multiple uses from sharing the internet and what is the consiquesnces if it where to happen?
If you want to control who can access an internet connected node (without turning on the "share internet" option, install a Socks Proxy server on a RPi on your network and tell users to configure their browser to use a SOCKS proxy.
