I think you’re either looking for a tunnelling solution or a Web Application Firewall. And there are several options. ModSecurity, or SafeLine, BunkerWeb, Coraza, open-appsec. For (AI) crawlers and bad bots we have Anubis, Iocaine… or something like more traditional blocklists or something like OpenResty which is some modified Nginx plus modules…
The tunneling itself can be done with a simple reverse proxy like Nginx, Traefik, Caddy…
I’ve messed around a bit with ModSecurity. But I’m still looking for something aganist the crawlers.
I’m afraid that won’t help. That was like 6 years ago and all the hardware isn’t available any more. It’s a Xeon 4 core, an affordable workstation/server mainboard that happens to be very efficient in idle, 48GB of RAM and a bunch of harddisks. I started out with 6TB and then bought the best size/price hdds, which should currently be somewhere in the 12-14TB range if I’m not mistaken?
I got the idea from the German computer magazine c’t. They occasionally test mainboards and do recommendations for self-built home NAS, office or gaming rigs.
