DNS Exfiltration Tool
Obligatory dns tunnel software for exfil. It is super noisy if you do dns querylogging, so I'd not use it for anything major, but it is a fun research tool.

Russia starts blocking VPN at the protocol (WireGuard, OpenVPN) level
While working in an environment where VPN connections were pretty much all blocked⁰ a friend of mine had success using https://guacamole.apache.org/ to access a remote machine¹. Not quite the same as a direct VPN connection but worth a try if nothing else functions, it looks enough like normal HTTPS traffic that he got away with it.
To keep your wireguard setup more as-is, you could try https://kirill888.github.io/notes/wireguard-via-websocket/ to tunnel that via a web server. In fact https://github.com/erebe/wstunnel which that uses could be used just as well with any other UDP based VPN.
I once tinkered with https://github.com/yarrick/iodine and successfully connected to resources over the wireless on a train, bypassing its traffic capture and sign-up requirement, so that might be an option, though I think fully blocking external DNS is more common now so this is less likely to work²³.

[0] practically only HTTP(S) permitted, not even SSH, DPI in use that detected just using SSH or OpenVPN over port 443
[1] NOTE: be careful breaching restrictions like this, you are at risk of an insta-sacking if discovered, or worse if operating in some securiry environments!
[2] and the latency when it does work is significant!
[3] and that much traffic over port 53 might get noticed by the heuristics of data exfiltration scanner, encouraging sysadmins to notice and implement a way to block it

Show HN: File distribution over DNS: (ab)using DNS as a CDN
There's also iodine, a C program that tunnels IPv4 packets over DNS. Useful for bypassing captive portals on wifi, since DNS usually isn't restricted.
https://github.com/yarrick/iodine
Regarding cloudflare DNS over HTTPS: It could be that it tries to server data encoded as JSON, which is impossible in JSON. Some control characters and bytes 128-255 cannot be represented as JSON strings.

Show HN: Use DNS TXT to share information
A regular proxy on port 53 might work? Is it necessary to actually use DNS?

help with choosing a VPN to host (I'll explain)
Well, you're really exhausting your options here (and possibly your IT department's patience). Iodine would still be an option, it creates a tunnel through DNS traffic. Nearly impossible to block/filter out but you shouldn't expect a lot of bandwidth. Try it out! Although if you're only going to use low-bandwidth applications through the tunnel anyway you might as well use your own mobile data plan instead of your school's WLAN.

Netflix Canada Just Got Rid of Its Cheapest Ad-Free Plan Without Even a Heads Up
> But I’m working on setting up a VPN at my house to tunnel all Netflix traffic through ...
On a technical point, you might be able to get away with just using Squid for the proxy, with pretty much default settings.
http://www.squid-cache.org
I used to use that years ago (not with Netflix though) running from a data centre, using an ssh (autossh) tunnel to reach it securely.
Worked pretty well, aside from the extra latency due to the packets having to go an extra half way around the world. ;)

How to get my IP traffic data to an AWS lambda using Darkstat?
I recommend trying a transparent proxy like Squid. There are many analytics tools for Squid logs. Squid can generate TLS certificates on the fly to inspect secure websites but you'll have to generate and install a CA certificate and key into Squid. You'll also have to import the CA certificate on any machine accessing the internet through the Squid proxy. Squid has the added bonus of caching content to speed up web browsing and reduce data usage.

Web resource caching: Server-side
A couple of dedicated server-side resource caching solutions have emerged over the years: Memcached, Varnish, Squid, etc. Other solutions are less focused on web resource caching and more generic, e.g., Redis or Hazelcast.

Why does linux use HTTP to get updates?
Also, the fact it is distributed by HTTP allow companies (and ISPs) to cache content in Squid servers (http://www.squid-cache.org/). And this is quite a feature!

How to monitor web activity on home network
If your router is compatible with custom firmware (Tomato or DD-WRT) you can flash it and use the logging features of those platforms. Otherwise no there isn't really an "app or software" that can do this, you need a piece of hardware that sits between the LAN devices and the internet connection. That can be a full-fledged computer, if you're willing to use it as firewall or router (pfSense), DNS server (PowerDNS) or proxy server (Squid).
