Hello,
just wanted to share that I have successfully hosted copyparty instance behind cloudflare on my porator laptop :D
you can use it to share memes or use it as temporary storage, I don't have any idea of how to manage a public facing service but I will figure it out.
Pro-Tip: You can reverse proxy any service on your network but if the IP of your reverse proxy does not match the IP of your A record, aka your server is behind a VPN, the public will not be able to access your server.
Http/s is neat that way, if the IP’s don’t match then it’s technically considered an insecure or misconfigured setup but it works great to prevent unauthorized access to one’s server.
I must agree with other users here, hosting a public file hosting server is a bad idea, at the bare minimum Authentik or Keycloak should be in front of it but I digress, https://catbox.moe/ already endures this pain for us.
Not sure what reverse proxy you’re using but alternatively Traefik’s middleware IPAllowList works great for blacklisting all IP’s and only whitelisting the known few.
