Everything critical is on lan (docs, passwords, media), everything else is on vps (gameserver, fediverse, websites). I dont mix these as I absolutely dont want to deal with a breakin. I assume they will get in so I airgap them more or less.
Unlike most here, I’m not as concerned with opening things up. The two general guidelines I use are 1. Is it built by a big organization with intent to be exposed, and 2. What’s the risk if someone gets in.
All my stuff is in docker, so compartmentalized with little risk of breaking out of the container. Each is on it’s own docker network to the reverse proxy, so no cross-container communication unless part of the same stack.
So following my rules, I expose things like Nextcloud and Mediawiki, and I would never expose Paperless which has identity documents (access remotely via Tailscale). I have many low-risk services I expose on demand. E.g. when going away for a weekend, I might expose FreshRSS so I can access the feed, but I’d remove it once I got home.
Doesn’t Nextcloud running in Docker want the socket exposed?
I googled around for an example https://book.hacktricks.xyz/linux-hardening/privilege-escalation/docker-security/docker-breakout-privilege-escalation.
Ignore me if you’ve already hardened the containers.
I’ve never known a reason to expose the docker socket to Nextcloud. It’s certainly not required, I’ve run Nextcloud for years without ever granting it socket access.
Most of the things on that linked page seem to be for Docker rather than Nextcloud, and relate to non-standard configuration. As someone who is not a political target, I’d be pretty happy that following Nextcloud’s setup guide and hardening guide is enough.
I also didn’t mention it, but I geoblock access from outside my country as a general rule.
I was looking into setting up Nextcloud recently and the default directions suggest exposing the socket. That’s crazy. I checked again just now. I see it is still possible to set it up without socket access, but that set of instructions isn’t as prominent.
I linked to Docker in specific because if Nextcloud has access to the socket, and hackers find some automated exploit, they could easily escalate out of the Docker container. It sounds like you have it more correctly isolated.
Was it Nextcloud or Nextcloud All in One? I’ve just realised that the Nextcloud docker image I use is maintained by Docker, not Nextcloud. It’s this one: https://hub.docker.com/_/nextcloud/
I use Docker-compose and even the examples there don’t have any socket access.
The all in one image apparently uses Traefik, which seems weird to use an auto configuring reverse proxy for an all in one image where you know the lay of the land. Traefik requires access to the docker socket for auto configuration. But you can proxy the requests to limit access to only what it needs if you really want to use it.
What I was looking at was the All in One, yes. I didn’t realize there was a separate maintained image, thank you! I’d much rather have a single image without access to the socket at all, I’ll give that a shot sometime.
One warning: in my experience, you can not jump two major versions. Not just it won’t work, but that if you try it everything will break beyond repair and you’ll be restoring from a backup.
Two major versions can sometimes be a matter of a few months apart, so make sure you have a regular update schedule!
(Also, people say never update to a X.0 release, the first version of a major release often has major bugs).
TL;DR don’t take too long to update to new releases, and don’t update too quickly!
Also, the docker image is often a day or so behind the new release, soNextcloud tells you an update is available but often you then need to wait until the next day to get the updated docker image. I guess this is because (as I’ve just learnt) the image is built by Docker not Nextcloud.
The only acessible element is the webserver. Fileserver, home automation, octopi, proxmox, media, etc etc are all isolate.
Everything is accessible, but only through n2n vpn.
Everything is accessible through VPN (Wireguard) only
Same. Always on VPN on phone for on the go ad blocking via pihole.
Same here. Taught my wife how to start WireGuard on her android phone and then access any of the services I run. This way I only have one port open and don’t have to worry too much.
That’s what I do. The beauty of wireguard is that it won’t respond at all if you don’t send the right key. So from the outside it will appear as if none of your ports are open.
How about running your wireguard server on a VPS and then connecting to the same interface as clients from your mobile and home network? No ports open on your side!
Available to the internet via reverse proxy:
- Jellyfin
- Navidrome
- Two websites
- matrix chat server
- audiobookshelf
LAN only:
- homepage
- NGINX Proxy Manager
- Portainer
There’s more in both categories but I can’t remember everything I have running.
What is homepage? I’m testing homarr right now (assuming it’s similar) but haven’t set on it yet
It’s another dashboard like homarr. I set up homarr and homepage side by side to pick one and landed on homepage. No specific reason, I just gravitated to it over homarr.
Thanks, I’ll check it out :D
You’re welcome!
I believe it’s this
I’ve been eyeing it myself
Woo thank you!
That it is!
I have HTTPS and SSH accessible on the internet but only over IPv6. Anything else I access over an SSH tunnel or VPN.
Everything is behind a wireguard vpn for me. It’s mostly because I don’t understand how to set up Https and at this point I’m afraid to ask so everything is just http.
I’ve been using YunoHost, which does this for you but I’m thinking of switching to a regular Linux install, which is why I’ve been searching for stuff to replace YunoHost’s features. That’s why I came across Nginx Proxy Manager, which let’s you easily configure that stuff with a web UI. From what I understand it also does certificates for you for https. Haven’t had the chance to try it out myself tho because I only found it earlier today.
NPM is nice and easy to use.
NPM is the way. SSL without ever needing to edit a config file.
Its not hard really, and you shouldn’t be afraid to ask, if we don’t ask then we don’t learn :)
Look at Caddy webserver, it does automated SSL for you.
Careful with Caddy as its had a few security issues.
All software has issued, such is the nature of software. I always say if you selfhost, at least follow some security related websites to keep up to date about these things :)
Do you have any suggestions for reputable security related websites?
too many :) Here is a snippet of my RSS feed, save it as an xml file and most rss reeders should be able to import it :) https://pastebin.com/q0c6s5UF
few days late here, but that pastebin had some really good feeds 🙏 I noticed the OPML file was labeled FreshRSS and I also use FreshRSS. So I fixed up the feeds and configured FreshRSS to scrape the full articles (when possible) and bypass ads, tracking and paywalls.
I figured I’d pay it forward by sharing my revised OPML file.
I also included some of my other feeds that are related (if you or anyone else is interested).
Some of the feeds are created from scratch since a few if these sites don’t offer RSS, so if the sites change their layout the configs may need to be adjusted a bit, but in my experience this rarely happens.
I had to replace some of the urls with publicly hosted versions of the front-ends I host locally and scrape, but feel free to change it up however you like.

Thank you :)
Thank you. It was mostly ment as a joke tho. I’m not actually afraid to ask, but more ignorant because it’s all behind VPN and that’s just so much easier and safer and I know how to do it so less effort. Https is just magic for me at the moment and I like it that way. Maybe one day I’ll learn the magic spells but not today.
Nothing is exposed. There are things I want exposed, but I don’t want to keep security patches up to date, even if there is a zero day. I’m looking for someone trustworthy to hire for things that it would be useful to expose, but they are hard to find.
Just VPN back in with WireGuard.
I think it would be better if you just setup auto updating regardless
something like 95% stays local and is remote accessed via wireguard, The rest is stuff I need to host via a hostname with a trusted cert because apps I use require that or if I need to share links to files for work, school etc. For the external stuff I use Cloudflare tunnels just because I use DDNS and want to avoid/can’t use port forwarding. works well for me.
Just in case you missed this, you can issue valid HTTPS Certificates with the DNS challenge. I use LetsEncrypt, DeSEC and Traefik, but any other supported provider with Lego (CLI) would work.
I keep everything behind a VPN so I don’t have to worry much about opening things up to the Internet. It’s not necessary about the fact that you’re probably fine but more so what the risk to you is if that device is compromised, ex: a NAS with important documents, or the idea that if that device is infected, what can that device access.
You could expose your media server and not worry too much about that device but having it in a “demilitarized zone”, ensuring all your firewall rules are correct and that that service is always updated is more difficult than just one VPN that is designed to be secure from the ground up.
As a general rule if it’s a pubic-ish service like Lemmy (more a friends and family than public) or something where I want ready access like auto uploads it has public access, otherwise it’s private. I make it a point to have everything facing outside to have 2FA enabled and/or limit the available sources to known IP ranges.
I currently keep everything LAN-only because I haven’t figured out how to properly set up outside access yet.
(I would like to have Home Assistant available either over the Internet or via VPN so that automations keyed off people’s location outside the home would work.)
Just recommendes something that could help you to someone else here
I have used DuckDNS and Nginx to get Home Assistant outside but it was horrible, just constantly breaking. Around Christmas time I bought myself a domain name for a few years and Cloudflare to access it, and it’s been night and day since.
Sure it cost me money but it was far cheaper than a Nabu Casa account.
Yeah, same, except I tunneled HA out via that Cloudflare daemon. Kinda janky because I cannot use the app with it to do locations, but I can check in on the pets from anywhere.
I’m planning to set up a legit VPN sometime soon.
Why can’t you use the app to do locations?
I cannot get the app to connect to my HA with the current setup. I have Cloudflare doing email verification, and the app doesn’t understand how to collect the cookies to make that possible.
Tailscale plugin for HA works flawlessly for me.
PII or anything that would demonstrate clear attribution is LAN, the rest of the “fun” stuff lives on a VPS. Wireguard between them.
I probably have more accessible from outside than not. Many are required: hosting a website, a media server I can access from anywhere outside the house, my phone system, etc. Some I used to use more than I do now: podcast service, that sort of thing. Then a bunch that are internal only. My phone connects home over Wireguard so that’s pretty convenient when out and about for accessing internal only systems.
