Hey guys,
after reading up on selfhosting for weeks now I finally decided to take the plunge today and tried setting up my own nextcloud & jellyfin instances. For this purpose I am using a mini PC. (similiar to an Intel NUC)
Now I would like to make both services available to the internet so I could show images to friends while I’m at their place / watch movies with them.
The problem is I am currently not very educated on which security measures I would have to take to ensure that my server / mini PC doesn’t immediately become an easy target for a hacker, especially considering that I would host private photos on the nextcloud.
After googling around I feel like I find a lot of conflicting information as well as write-ups that I don’t fully grasp with my limited knowledge so if you guys have any general advice or even places to learn about all these concepts I would be absolutely delighted!
Thank you guys sooo much in advance for any and all help, the c/selfhosted community has been nothing but a great resource for me so far!!!
i have a lot of stuff exposed to the web. i got a domain from godaddy, attached my public ip and created a subdomain for each service. than i have traefik that manage the tls and route each subdomain to each of the docker containers.
in total i have exposed 80, 443, and a random port i use for ssh. of course ssh is only by public key.
now i’m trying to set up fail2ban on the exposed services since someone could bruteforce them.
That sounds pretty cool. So far, I have everything running behind vpn but a more integrated solution would totally make sense. A lot of apps have their own brute force throttling (such as nextcloud) btw.
i’ve added my server config as edit so you can go check it out.
i heve owncloud instead of nextcloud.
I‘m really sorry. I don’t see your edit. Checked all your comments as well. Maybe I‘m overlooking it.

Thats quite an elaborate list you have there! Thanks for sharing! I‘d need to heavily sanitize and structure my log to be able to put it on github. Good job! :)
