Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

Set up a reverse proxy with https always on. And get a good (physical) firewall, preferably something akin to opnsense, pfsense, openwrt. Exposing is always a risk, and if you do want it, you have to bear the responsibility for your own security. Keep things up to date, set up monitoring and a good logging system (Wazuh) comes to mind.
Exposure means a security risk. How you deal with that security risk is your choice.
Cloudflare and the likes forbid usage of their stuff for these things.
How does a reverse proxy helps for security? I mean, the problem here is that exposing Jellyfin on the internet is dangerous: the only way to improve security via a reverse proxy would be mTLS, but I'm not sure how it would work client side.
By setting up a reverse proxy you redirect the traffic through that specific proxy which means less open ports (basically just 80/443), less monitoring, the ability to easily put a WAF inbetween, etc.
You've got a couple benefits. If you have a domain name, and aren't advertising it publicly, then you can use the reverse proxy to point that domain to a non-standard port that Jellyfin runs on.
Security through obscurity is not good security, but it does prevent the majority of port scanning attacks. You can also use fail2ban on the reverse proxy side to try and mitigate some attacks.
Cf used to have it against the rules, but it's fine now.
Ah cool, didn't know!
