yeah. have a raspberry pi with nginx reverse proxy to bitaxe and tor hidden service. works like a charm.

Is there a guide on how to set this up properly?

You can also set the Bitaxe up behind an OpenWRT wifi router, setup Tailscale on the router and access the Bitaxe behind the router via Tailscale.

not that i kow off, but roughly simething like this: 1. I note the port and IP the bitaxe runs on. 2. install and configure nginx with reverse proxy in the rpi, and where proxy_pass is yhe bitaxe ip and port.

NGINX Reverse Proxy | NGINX Documentation

Configure NGINX as a reverse proxy for HTTP and other protocols, with support for modifying request headers and fine-tuned buffering of responses.

3. install and configure tor with hidden service on the rpi.

Onion services

Onion services (formerly known as "hidden services") are services, like websites, that are only accessible through the Tor network.

4. go back to your nginx config and add the onion address to server_name. 5. pissibly reboot. check some logs and visit your onion address using torbrowser. Note: you do not need SSL certificates since the onion address works with asimilar cettificate tech. I have a great time with hidden services, it makes it so I dont need DNS! hope this helps
