How does Linux NAT a ping?
Not exactly what you're looking for, but your comment about abusing pings made me remember pingfs [1]. It brings an entirely new definition of cloud computing!

- Anything can be a message queue if you use it wrongly enough
- Store files inside of YouTube videos

ESXi Host just crashed. That host had our file server on it.

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 blockedā° a friend of mine had success using https://guacamole.apache.org/ to access a remote machineĀ¹. 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 workĀ²Ā³.

[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.
