Interesting back-channel: [Wayback/Archive] BASE64 Over DNS – SANS Internet Storm Center covered in the blog
It reminds me over other tunneling techniques over DNS like the below VPN over DNS one that have existed for quite a while now (for instance in Captive portal: DNS Tunneling).
Last year, it raised attention because of [Wayback/Archive] MystRodX: The Covert Dual-Mode Backdoor Threat.
Nothing new though, but still interesting (:
Anyway, some links on stuff that has existed for a while:

Lot’s of power supplies on [Wayback/Archive] MikroTik Routers and Wireless – Products, most (except the internal ones) I listed below grouped by output voltage and amperage (and wattage which I rounded down).
I didn’t realise there were so many and that there basically is no consistent naming scheme.

It’s a tricky process, but I might need this in the future:

On OpenWRT GL.iNET based devices, the WireGuard client does not restart upon reboot, even if it was started before rebooting.
Hopefully the /usr/bin/wireguard_watchdog script will help with this as others indicates it should.
My first try was no succes, but since it is supposed to run from cron it does no output. The script on GL-SFT1200 firmware version 3.215, script /usr/bin/wireguard_watchdog is different from the one in the OpenWRT repository, so it needs some investigation.
Some links for checking this out:

TL;DR: the connection problem was because of a public key mismatch between the pfSense central location and GL.iNET peer.
Since the pfSense cannot export configuration in either text or QR format (see 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.), I made a copy paste mistake.
This resulted in the WireGuard client connection indicator on the GL.iNET to turn yellow instead of green. This means that the handshake is only partially completed (there is a WireGuard connection but there is no returning traffic on it).
GL.iNET VPN status explanation:
- no color: no VPN
- yellow: VPN not fully established
- green: VPN established

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).

TL;DR: it failed
Since GL.iNET does not support site-to-site “Peer to Peer” OpenVPN (only “Remote Access” is supported) which is needed to route to/from the networks on both sides of the connection. the below did fail.
Original idea
Below was what I hoped to function.
Some links that should get me started (though my situation is a tad more difficult, see below):
