What’s your go too (secure) method for casting over the internet with a Jellyfin server.
I’m wondering what to use and I’m pretty beginner at this

I just expose my local machine to the internet, unsecured
I see everyone in this thread recommending a VPN or reverse proxy for accessing Jellyfin from outside the LAN. While I generally agree, I don’t see a realistic risk in exposing Jellyfin directly to the internet.
It supports HTTPS and certificates nowadays, so there’s no need for outside SSL termination anymore.(See Edit 2)In my setup, which I’ve been running for some time, I’ve port-forwarded only Jellyfin’s HTTPS port to eliminate the possibility of someone ending up on pure HTTP and sending credentials unencrypted. I’ve also changed the Jellyfin’s default port to a non-standard one to avoid basic port-scanning bots spamming login attempts. I fully understand that this falls into the security through obscurity category, but no harm in it either.
Anyone wanna yell at me for being an idiot and doing everything wrong? I’m genuinely curious, as the sentiment online seems to be that at least a reverse proxy is almost mandatory for this kind of setup, and I’m not entirely sure why.
Edit: Thank you everyone for your responses. While I don’t agree with everything, the new insight is appreciated.
Edit 2: I’ve been informed that infact the support for HTTPS will be removed in a future version. From v10.11 release notes:
Deprecation Notice: Jellyfin’s internal handling of TLS/SSL certificates and configuration in the web server will be removed in a future version. No changes to the current system have been made in 10.11, however future versions will remove the current system and instead will provide advanced instructions to configure the Kestrel webserver directly for this relatively niche usecase. We strongly advise anyone using the current TLS options to use a Reverse Proxy for TLS termination instead if at all possible, as this provides a number of benefits

Not yell, but: Jellyfin is dropping HTTPS support with a future update so you might want to read up on reverse proxies before then.
Additionally, you might want to check if Shodan has your Jellyfin instance listed: https://www.shodan.io/
Nginx in front of it, open ports for https (and ssh), nothing more. Let’s encrypt certificate and you’re good to go.
I would not publicly expose ssh. Your home IP will get scanned all the time and external machines will try to connect to your ssh port.

Anything that’s not specifically my username or git gets instantly blocked. Same with correct users but trying to use passwords or failing authentication in any way.
They can try all they like, man. They’re not gonna guess a username, key and password.
Doesn’t take that to leverage an unknown vulnerability in ssh like:
That’s why it’s common best practice to never expose ssh to raw internet if you can help it; but yes it’s not the most risky thing ever either.
If you’re going to open something, SSH is far, far more battle-tested than much other software, even popular software. Pragmatically, If someone is sitting on a 0-day for SSH, do you genuinely think they’re gonna waste that on you and me? Either they’re gonna sell it to cash out as fast as possible, or they’ll sit on it while plotting an attack against someone who has real money. It is an unhealthy level of paranoia to suggest that SSH is not secure, or that it’s less secure than the hundreds of other solutions to this problem.
Here is my IP address, make me eat my words.
2a05:f6c7:8321::164 | 89.160.150.164You got balls to post you public addresses like that… I mean I agree with you wholeheartedly and I also have SSH port forwarded on my firewall, but posting your public IP is next-level confidence.
Respect.
Well, having a domain is basically documenting your IP publicly. It’s not that risky.
Are you giving random strangers legal permission to pentest you? That’s bold.
