For your own personal items? It's not really worth it IMO. However if you're hosting something for the public, like a Lemmy server, then absolutely yes you should.
For Emby that is breaking their ToS, and you'll have a big corpo watching your traffic all the time. Just buy a cheap 5-10 dollar domain and get HTTPS up and running and you'll be fine.
I just worried about attacks on my router in case someone gets ahold of the link. Im learning all this security stuff. I actually helped my friend with his lemmy instance and got it running.
I just know next to nothing about security...
Give me something to try and get working I'll pick it up, but I don't even know where to start with this stuff. I read something the other day about using cloudflare to connect to a VPS and then direct that to my nas or something.
I have 2 VPS services and 1 already hosts my jellyfin instance but i was gonna try out emby however, I wanna share my library with family like I share my Jellyfin with them. Just the VPS I run my jellyfin on handles all the security stuff. shrugs
To reduce that, there are a few things you can do.
Option 1:
Only open port 443 and run everything through a reverse proxy like traefik. You can open other ports ad you need them (game server for example)
Run crowdsec to get rid of 95% of bad actors
Whitelist IPs that you know traffic will be coming from and drop everything else
Option 2:
Option 3:
Run tailscale
run fail2ban
Absolutely a fair reason to be nervous. For this just follow the rules of minimum access. Only open the ports you need to open, and make sure they only point to the item you want to expose. That will take care of 99% of use cases. Most hacks you see happening right now with home labs are because someone did something pretty obvious - like exposing their router/firewall UI to the open internet (instead of it only being accessible to the local network), same with their data servers.
If you have a good network you can even restrict which IPs are allowed to connect through those ports, but remember if your mom's IP changes or you're sitting in a hotel then you're essentially blocking yourself out (without a VPN or something).
Finally, and I would save this for a little later, you can move your Emby/external services to an alternate VLAN. VLANs are virtual-lans, they are a block of IPs that have firewall rules in between each of them. So you could do rules like "Internal clients can talk to Emby, but Emby cannot talk to Internal Clients". This can be a daunting thing and will take a lot of trial and error, not to mention probably revamping your entire network - so I'd hold off for now.
I wanted to do vlan , but that would mean no more super fast local access
It's been a while since I've heard anything about this but didn't they change their ToS in regards to media on their network? I thought I read something about that clause getting removed at some point a few months back.
Maybe. Personally it's just another huge corpo that's reading my traffic. There's a dozen other middle men, but no doubt cloudflare wouldn't hesitate to release all of my traffic at a moment's notice.
That's a fair point, I self host stuff more out of convenience over privacy (although that's still a factor) so I guess I just care less about them watching my traffic I suppose. CF is just so easy with their Argo Tunnels and domain registrar service.
I believe media hosting is only against their ToS if you try and use the proxy service. In the DNS page you would want to make sure the clouds are not orange. Fair warning though now your IP is exposed to the public.
I use their tunnels in conjunction with internal split horizon DNS so I don't have to forward any ports and can access things locally faster so I'm probably breaking this rule but I haven't gotten any emails or letters about it yet. Crossing my fingers they don't care lol
Can this be done with an ISP that gives you a dynamic IP? I have a domain through Google Domains, I just have no idea how to set it up for Jellyfin
Look into dynamic DNS. It's for your exact case, when your up updates you need to update the DNS host with your new IP. Idk if Google domains does it, I use it with namecheap and then there's an option in offense that will tell namecheap that my IP has changed.
This isn't a "production" worthy option because there can be downtime when your Ip switches, but for us it's perfect.
