Some networks, e.g. Azure VNets, are quite restrictive about the supported procotols. Azure for example only supports TCP and UDP. Fortunately there is the Foo-Over-UDP ("FOU"), tunneling over UDP and thus bypassing the Azure limitation.

1. You need a Linux distribution that supports FOU, for example Ubuntu.
   RHEL for example does not support FOU (so Fedora and CentOS probably neither).
2. the fou module must be configured to be loaded automatically. (modprobe fou, /etc/modules.conf)
3. choose your "foo": e.g. IPIP.
   Check your OS docs what other protocols are supported, for example via man systemd.netdev.
4. sending and receving FOU is separated, you will need to create on device for each:
   1. create one device for sending/encapsulation (fou-tx, fou-tx.netdev)
   2. create one device for receiving/decapsulation (fou-rx, fou-rx.netdev)
5. attach networ

Proxmox + acme.sh

Using acme.sh on the proxmox host to generate Letsencrypt certificates

With this we show how to use acme.sh instead of the original Letsencrypt interface.

Acme.sh is just a Bash script that can run on pretty much any *nix environment.
It is quite simple but also quite powerfull.

In this guide I will use the cheap and good Dynu service to configure a domain.

VFIO Setup Guide

I play games regularly, and the sad reality is that it forces me to use Windows on my desktop. There's a Linux installation on there, but rebooting into it is such a massive interruption that I usually just move over to my laptop for programming. Working on a laptop leads to all sorts of ergonomic issues, and it felt like a massive waste to not develop on the desktop hardware I invested so much in. So after extensively researching what the VFIO community has been doing, I've deleted my Windows installation and moved all my gaming into a virtual machine on a Linux host.

Normally VMs are too slow for gaming, but thanks to a feature called VFIO you can run games at near-native performance by passing graphics cards and USB controllers directly to a virtual machine. The only requirement is that your board supports IOMMU, which most modern systems have. In this guide I'll wal
