Everytime when installing a pfSense router from scratch, I seem to re-learn a few of the below quirks. So it was finally time to document them (:
Quite a few of my pfSense configurations are just doing routing between various networks, should not provide DHCP leases and do not always need or have a WAN connected (i.e. they are LAN-only).

This is actually the WireGuard package you can install on pfSense CE 2.5.2 and higher: [Wayback/Archive] rcmcdonald91/pfSense-pkg-WireGuard: This is a port of the original WireGuard UI bits as implemented by Netgate in pfSense 2.5.0 to a package suitable for rapid iteration and more frequent updating on future releases of pfSense.
Note that the source code mentions a lot of web-technologies but that is because the majority of the code is the pfSense plugin. Underneath it pulls the actual build from [Wayback/Archive] git.zx2c4.com/wireguard-freebsd/snapshot which is almost exclusively C code.
Like WireGuardNT on Windows, it uses a high performance kernel mode driver.
Some more links on it:

[Wayback/Archive] version control – How can I see the changes in a Git commit? – Stack Overflow (thanks [Wayback/Archive] laktak, [Wayback/Archive] Nevik Rehnel, [Wayback/Archive] Juuso Ohtonen and [Wayback/Archive] User c z – Stack Overflow)
This looks like a valid question, but in reality it is not.
The thing is: in git, think of a commit not as a diff but as a snapshot*.
A diff is the difference between two commits.
Since most commits have just a single parent, so that’s why many people call a commit a diff. But that’s not true, especially not for merge commits that have at least two parents.
Anyway, the question, answer and comment from the link above already give some insight (note COMMIT everywhere below has to be replaced with the commit hash):

Despite UML (Unified Modelling Language) not having a specific diagram mode for computer networks, PlantUML does support a computer network diagram mode.
Here are some links that got me going to design a site to site VPN situation that I will document in more detail later on this blog.

I used [Wayback/Archive] How could i get a permanent link for raw file? · community · Discussion #22537 · GitHub to go
The reason I needed it is that for quite a while now, GitHub has started to display PDF files as preview, and modified the download behaviour to get a blob: link instead of the actual raw file download location.
On the to do list:
Thanks [Wayback/Archive] Lotaristo (Czeslaw Meyer) and [Wayback/Archive] byrneh (Hugh Byrne)

Such a cool historic artefact: [Wayback corbosman on Twitter: “Just found this highly advanced drawing of the network setup at HIP97. The ??? probably meant we didn’t have the hardware for it yet.”
It is a nice addition to the existing HIP97 information, of which some is at:
