Bypass CGNAT for Plex via your own Wireguard VPN on a VPS

Intro

I just recently switched to an ISP that uses CGNAT. I needed a way to access my Plex server remotely now that I didn't have a public IPv4 address. Thankfully for most of my other web hosted projects, I was able to use Cloudflare tunnels. But it's ambigous if Cloudflare is okay with you using Tunnels for Plex traffic.

Instead people suggested buying a VPS and hosting a VPN (like Wireguard) to route your traffic through. I couldn't find a complete guide to do this. I struggled for a couple days with trial and error until I finally found a configuration that worked. I wanted to document this for anyone else in the same situation (and future me).

Prerequisites

For my reference in the future I will record here the steps that I had to follow in order to install Openwrt on the tp-link router EX220. This was done using a Windows 11 machine.

How to Install kitty in Ubuntu in WSL2

These seteps have been tested on Windows 10 with WSL2 running Kali Linux.

1. Dependencies

First install the dependencies:

Install OpenGL

In the last years I've been asked multiple times about the comparison between raylib and SDL libraries. Unfortunately, my experience with SDL was quite limited so I couldn't provide a good comparison. In the last two years I've learned about SDL and used it to teach at University so I feel that now I can provide a good comparison between both.

Hope it helps future users to better understand this two libraries internals and functionality.

If you'd like to keep up-to-date with Chrome from unstable but otherwise want to run a stable NixOS release you can do the following:

Create a file /etc/nixos/unstable.nix:

{ config, pkgs, ...}:
let
  baseconfig = { allowUnfree = true; };
  unstable = import <nixos-unstable> { config = baseconfig; };
in {

Improve Fonts

Newest

Make your Arch fonts beautiful easily! This is what I do when I install Arch Linux to improve the fonts.

You may consider the following settings to improve your fonts for system-wide usage without installing a patched font library packages (eg. Infinality):

Install some fonts, for example:
sudo pacman -S ttf-dejavu ttf-liberation noto-fonts

Some hosting providers like scaleway allows to remove the IPv4 from the VPS in order to save 1€/month but doing this will result in losing connectivity to the "IPv4 world".
Or you may have ordered a VPS that only has IPv6 connectivity and you want to access to a resource only accessible from the "IPv4 world".
Here is how to gain your access back to the "IPv4 world".

Change your name servers(s) to DNS64 name servers(s)

Note: You may deploy your own DNS64 & NAT64 server on a separate server by following this tutorial (untested): https://packetpushers.net/nat64-setup-using-tayga/.
Note²: You may find a explanation of what is NAT64 and DNS64 on Wikipedia.

Choose a/multiple DNS64 public server(s) that has/have its own NAT64 public service from this list:
