Applications internet usage whitelist

Haven't found anything useful, so I'm gonna ask here. How can I block every piece of software from going outside LAN by default? And allow everything that needs internet through whitelist. The reason - privacy. Don't want anything "phoning home" without my approval. I know it's beyond paranoid, but would like to know if it's possible.

Firejail does that, but I'm not sure firejailing everything by default is a good idea.

Re: Applications internet usage whitelist

For the OPs goals I'd invert the logic on the serverfault answer.  Allow outgoing traffic in iptables from a specific group name (internet, yesinternet, whatever) and reject all other output.
