Wireguard and iptables restrictions for multiple users

If you don't know what Wireguard is, well, you should. It's fast, easy to setup and highly configurable. We will configure Wireguard for multiple users with various restrictions using iptables.

Assumptions

This should fit most setups (not mine though 😉)

direnv on Windows

Overview

In JavaScript projects, I used to use dotenv so that I could put local environment variables in a .env file for local development. But dotenv requires you to add code to your project. With direnv, you can put local env vars in a .envrc file and those env vars are loaded automatically in the shell.

Steps to install

For these steps, it is assummed that you have installed Git Bash on Windows. I also use VSCode as my editor.

Create a folder such as c:\tools to put the direnv.exe file and add it to the Windows PATH
