Running a TrueNAS Scale server with Jellyfin and planning to add Nextcloud. How would I be able to access these services from outside my network? I have heard portforwarding is unsafe and a VPN seems inconvenient to me.

    Port forwarding is unsafe, but even crossing the road is unsafe. Do you cross the road without watching? In the same way, you just don’t let a published server online without doing regular updates. You set up docker, run nextcloud (docker) behind nginx proxy manager, and have watchtower update them regularly. You can also setup 2fa in docker, and pair it with fail2ban.

    Every port open widens the attack surface, but those services are made to be published, so there are mitigations against the risks.

      I’ve said this many times before, but it seems relevant here, too. Using a reverse proxy is a good step for security, but you will still want to block certain incoming connections on your firewall. I block everything except for our cell phone provider, my partner’s employer, and my employer. We will never be accessing my network from any other source. At the very least, block everything and whitelist your own country; this will prevent a lot of illegitimate connections. If you’re using pfSense, the pfBlockerNG plugin makes this very easy to do.

        Yeah, absolutely good point, it’s something that can be done in opnsense as well. Certainly blocking any bloc outside your country (or region maybe in Europe) makes sense. I block everything outside RIPE, and also China and Russia.

      How does watchtower work with compose stacks? Does it update the whole stack (docker compose pull && docker compose up) in one go or each container individually?

        Found out the hard way, it does not. Now I just run a script every week (pull and compose up)

          That’s my current solution, just hoped I could properly automate that

        AFAIK one container at a time. Since the different parts of a stack (e.g. app and db) have different release cycles it’s not a problem (or it hasn’t been for me).

        Also, the important bit (from a security perspective) it’s the front end (i.e. the web app).

      and have watchtower update them regularly

      Does this help with Nextcloud on docker?

        If you use the linuxserver.io image, as of last month yes. They migrated to everything updated through the docker container.

        Now you make a good point, you also have to perform the update within the app in nextcloud. I use a custom image so I have to do it anyway, I haven’t realised that.

        But I guess npm is the one that needs to be updated automatically to avoid most of the attacks on the web
