Most things people self host are either torrent clients, HTTP(s) or are game servers. The first one can pick a port arbitrarily. The second can do host routing. The third - some of them support SRV records so you can direct the client to an arbitrary port. It’s becoming less common to need multiple public IPv4 addresses.

I’d contact Ninja support about it, but the likely answer is that it’s not possible

You could try putting up a cloudflare proxy and Turnstile (their captcha product) to try to help with it.

The truth is, though, if it’s static content, then you have to be able to stop them every time. Once they get it once, they got it. With how frequently they can try, it’s going to be difficult to stop them.

It’s up to you. Things to consider:

• Size of data
• Recovery speed (Internet speed)
• Recovery time objective
• Recovery point objective (If you’re backing up once per day, is it okay to lose 23 hours of data when a disk fails?)

If your recovery objectives can be met with the anticipated data size and recovery speed, then you could do RAID 0 instead of RAID 1 to get higher speeds and capacity. Just know that if you do that, you better be on top of your backups because they will be needed eventually.

Ugh but it’s acting as the SAN so I have to shut down like all my servers to run updates on it. What a PITA.

Idk but I wouldn’t risk it when it’s easy to encrypt stuff. Good security is done in layers.

What about a torrent? You’ll have to encrypt with 7zip or something to keep it secure, but that and qbitorrent will do the trick.
