I want to expose my services publicly on my own domain name, how would you guys do that?
I have seen people using Cloudflare, but I don’t want to use Cloudflare out of principle. I have also seen stuff on caddy and frp that I’ve done some rough researching.
What do you guys do?
Reverse proxy is what you need. I would post instructions here but honestly they wouldnt be that good. Just search it up and follow along.
Authentication & single sign-on service
Plugged into Reverse proxy, routing to each service by name
With a wild card cert so there are no name leaks.
Make your urls unexpected. If your domain is example.com, don’t put your jellyfin server at jellyfin.example.com. Instead, use watch.example.com or telly.example.com. Anything that’s memorable to you about what the service is without using a specific brand name.
With a wildcard dns record to point all names to your IP, and a wildcard certificate that works for all names loaded on your load balancer, it becomes hard for a hacker to know what name to use to get the load balancer to send them to the service they want to hack.
If you then use a sso tool like traefik’s ForwardAuth middleware, you won’t even get to the service until you’ve first authenticated.
If you use TLS like you should, your domains will be on the internet in the certificate transparency log. You should use a wildcard cert if you want this security by obscurity.
Security by obscurity is when the design or archetecture of the system is obscure enough to supposedly styme attackers (it doesnt), and as soon as people understand the design, your security is broken.
A hard to guess unpublished subdomain is a transparent and standard archetecture - nothing obscure about it and publishing that you use such a scheme doesnt break the security.
The subdomain is a bearer token that serves as an access control and just like a key or passphrase, has a security value proportional to the bits of information an attacker has to guess.
The real limitation is that browsers and humans are not great at not leaking domain names, so its very possible it will get leaked eventually and hard to rotate. Thats the reason they are weak. Still, they can be usefull to stop scanners just trolling for unpatched services.
Of course. The goal here is to not advertise. Make it hard for the bots to find you. With these steps, they can try your IP, but there’s nothing directly on your IP.
You still need proper security. Authentication is a good start, and it has the extra effect of adding an extra layer to prevent the bots from going further if they get lucky and guess a host name.
Or run an internal CA
Why do you want to expose them? This might limit the solutions.
The way I do this is in 2 different ways:
Tailscale, my server connects to tailscale so all I have to do is connect to it from my phone and I can access things remotely easily. This is the best for most things, but has the downside that others can’t access it as easily
I have a VPS (two actually at the moment as I’m switching providers from Vultr to IONOS) that also connects to tailscale so it can access my home server through it, then using Caddy I expose the services on a subdomain of the VPS. This is what I do for things that others might want to access, or things I don’t want to have to connect to tailscale to access.
If you’re going down the second route do consider that you will need to:
I recently switched to Netbird on a VPS (on Vultr). Their reverse proxy is super easy to set up / self host. They also offer a free version that works pretty good too, I just wanted to make it difficult for myself (thats the whole point of self hosting, right? )
I have seen netbird pop around every now and again. I might try out their cloud free version first and if I like it I might try self hosting it.
So you host netbird on a vps you rent and that is used for reverse proxy? So with that reverse proxy I can have my home server be publicly accessible and I can have friends log in to my jellyfin server without having to connect to my tailnet.
My last concern is security. How is this set up good for making sure I don’t just get constantly botted and exploited?
Yup! They can either connect to your Netbird meshnet (ie, similar a tailnet) or you can reverse proxy it out to the internet (no tailnet needed)
I saw a couple comments below concerned about security, one of the nice things about Netbird is that they have reverse proxy auth built in if you want. Some stuff (Navidrome or VoidAuth for instance) only has geolocation locked down (US only) but other things that I’m either more concerned about or don’t necessarily trust being open (Paperless or Komodo for instance) have Netbird Auth and VoidAuth as sign in options before it will let me open the page. Its worked flawlessly so far, and has kept my sanity intact because I wanted some stuff publically accessible without it being OPEN.
As far as being hammer fucked, it has CrowdSec and Geolocation lockdowns so you can set it to only accept traffic from ONE location and the Crowdsec also catches everything.
innocentzero@kbin.earth 3 weeks ago Opening jellyfin up publicly is kind of asking for trouble if you ask me. I haven't done so myself, but seen enough on this community and elsewhere to know that it's probably not a good idea.
I do this albeit with Tailscale. Netbird/Tailscale would act as a node of your VPN and you can configure reverse proxy routes (via tailscale serve or Netbird’s equivalent) from the VPS edge to the homelab. You can even do SNI passthrough and have TLS terminated at your home, if you want, though this can be a bit slower
Alternatively you can even expose stuff via their servers. Tailscale Inc calls this service Funnels, and Netbird should have similar offerings. It’s kinda like Tunnels, though a VPS is greater as a dedicated entrypoint.
Lastly yes you’d be exposing the service to the general public internet, so some basic security is needed. Netbird has a Crowdsec module integration, might wanna look at that one and set up rules/detections. Consider putting extra auth in front of Jellyfin, use Authelia or something with an auth screen. And only expose the stuff you need, not your internal dashboard or whatever admin UI.
innocentzero@kbin.earth 3 weeks ago You're probably misunderstanding what netbird does (unless I'm the one misunderstanding things?).
Netbird subnet is equivalent to a tailscale tailnet (for all practical purposes; they even both use wireguard and hole-punching underneath). Netbird is not a reverse proxy (which I feel is what you think based on your comment).
Just a reverse proxy, I was using Caddy, moved to Pangolin because it’s neat.
Netbird reverse proxy: https://docs.netbird.io/manage/reverse-proxy
It’s like Tailscale, but Open Source. You can self-host the components, if you want. I just use the cloud offering. I have a domain name that resolves to my server. There’s different ways you can do auth. I just hard coded an allow list of IPs. Otherwise, devices in my Netbird network can use the private IP.
i configured dyndns in my router and have it forward all traffic to a gateway vm running nginx and fail2ban. every service is on a subdomain so any attempt to fetch things from the main name gets banned.
DrunkAnRoot@sh.itjust.works 2 weeks ago I personally use a vps for this stuff but my setup is standalone nginx as a reverse proxy and fail2ban and ufw
For those of us behind double NAT (CGNAT) forwarding ports is not an option as we do not control forwarding on the second gateway. This will limit you to any of the solutions that include a device outside your network with a public port that tunnels traffic into your server.
I’m not behind CGNAT/double NAT but I’m curious, can you use IPv6 to bypass that?
To some degree yes. I ran an experiment to see and found there is just too much of the existing internet infrastructure not implementing IPV6 for this to be reliable. For instance, you can’t use it for email intake because only 2 major players do IPV6.
You still get dynamic assignments from the ISP and have to automate keeping your AAAA records up to date.
The short answer is, it depends. For what OP is doing here, I expect it would work.
If anyone else has messed with this, I’d love to here about it. Might be good as it’s own post.
KarnaSubarna@lemmy.ml 3 weeks ago Make it publicly available to the world or just for you (and people you know)?
Publicly to the world. For example, I wanted to self host temporary file sharing and temporary link shortener to the world. Stuff like jellyfin I would have that public but only specific users would have the credentials to log in.
whatsherbucket@lemmy.world@lemmy.world 3 weeks ago My router (gl-net) has a VPN server built in. I just use WireGuard client and freedns.
Recently set up caddy myself, very straightforward setup. You essentially just edit one config file and point your domain host to the right place and are good to go. Took me by surprise actually.
Yeah but my main concern is security. If I publicly have services like jellyfin or something then I would think I would have constant exploits and bot attacks
You will.
Anything you expose should be designed for it (e.g. not jellyfin). You should have a WAF configured for the type of service you’re hosting. You can’t just drop one and have it magically protect you, they take configuration. Same with fail2ban.
And you should have these services in a DMZ, so that a compromise in one doesn’t provide an entry point to other resources on your network.
Oh for sure. I would only do so if you have a proper firewall running, a DMZ set up. Among other precautions.
What I do: VPS with reverse proxy and ssh reverse tunnels from the homelab.
OG would be to understand IPv6 and use that directly. Depending on the services you plan to expose that could be a good way. Tried it some years ago, was hit and miss and I still don’t get my head around how v6 work…but that would be the most independent, standalone way.
I bought myself a Synology disk station and a domain.
Yes I use Cloudflare for DNS so I can get a wildcard domain cert using ACME.
I use the Synology supplied login portal as a web application firewall for every site I want to host with the wildcard SSL cert. Like bar.mydomain.com, mealie.mydomain.com, etc.
The Synology routes the traffic to the services hosted on other services within my network.
Anything else I don’t want open to the public web, I use the Synology supplied OpenVPN server to connect.
I also have a synology but my old gaming laptop does video transcoding better so I have it on debian right now and am figuring out the best set up to access it and self host services to access publicly
Netbird has a reverseproxy that’s super easy to setup to point to one of your netbird nodes.
If you have a UniFi gateway, you can enable region based firewall on your port forward ip. This then blocks most of the world (incoming) as a first step. Then like others suggest, a reverse proxy. I use Caddy built with the Maxmind geolocation plugin, and I also run fail2ban on my exposed service.
I figure if you don’t need most of the world accessing your services, it is best to exclude them
MagnificentSteiner@lemmy.zip 3 weeks ago I use ingresses like traefik and the gateway API leaving my cluster. Then a wire guard tunnel to my DMZ to get to those. With keyclock for SSO.
I want to try Teleport for finer grained access then vpn but thats a future project
I have a Flint 2 with a vanilla install of openWRT, that hosts wireguard. I have 2 static IPs, because I thought hey running my own mail and smtp services cannot be that hard (turns out yes it is hard and not worth the time to deal). Any who I have Wireguard running on my firewall and Caddy running on one of my pi’s, it gets TLS from lets encrypt.
I have a couple of domains that Caddy uses to point things out to the world or my LAN/vLANs/VPNs. Very few of the things go out to the whole world, but if I wanted to share say a Jellyfin server with someone I could wip up a VPN that only allows Jellyfin through and points DNS to my piholes. Why do I mention my ad blocker? I mention pihole because that what hosts the prefix to my domain names that Caddy can serve up, I do not remember why I set it up like this, I would have to look through my notes but pihole points “service”.domain1or2.xyz to caddy which than points to the right service.
I use traefik combined with crowdsec, there is a plugin for that. There is some pretty good tutorial (in german) on goneuland.de

Is the server at your house? Or VPS?
My server is at home
The way that I handled this, was to get a $5 VPS, and have it proxy all my traffic over wireguard. Your DNS records (and SSL cert) all point to the VPS public IP address. IPtables rules route all relevant traffic.
spork@pawb.social 3 weeks ago
I rent a cheap VPS with iptables routing ports through a wireguard tunnel to a peer on the local network that acts as a firewall and reverse proxy.
pineapplelover@lemmy.dbzer0.com 3 weeks ago
What’s a cheap vps you recommend?
sulfidedisburseangledafternoontipper@piefed.blahaj.zone 3 weeks ago
I use a cheap racknerd vps via low end box. $12/yr.
spork@pawb.social 2 weeks ago
I hop around a lot. I’ve used Akamai (fka linode), Vultr, DigitalOcean, AWS EC2, and GCP Compute Engine. I wouldn’t recommend the last 2 anymore because fuck big tech. A lot of people will mention Oracle’s free tier, but I don’t trust anyone that looks like Larry Ellison to own a machine with a direct connection into my local network.
TheRedSpade@lemmy.world 3 weeks ago
Linode has a $5/month option.
state_electrician@discuss.tchncs.de 3 weeks ago
Oracle has a free tier where I run my Wireguard.
shadshack@feddit.online 2 weeks ago
Look into Oracle cloud’s Always Free tier of cloud instances. I have a few of those and they’re decent for free.
HelloRoot@lemy.lol 3 weeks ago
Same but nftables and also crowdsec.
Also I had some trouble with the wireguard tunnel dropping lots of packets, which resulted in my services not loading 50% of the time. I did a lot of suggestions at the same time so I’m not sure which one fixed it but here is a list in case anybody has similar troubles:
hirihit640@sh.itjust.works 1 week ago
I’m running into similar issues, do you mind expanding on your solutions?
halcyoncmdr@piefed.social 3 weeks ago
Similar here. Just a Digital Ocean droplet running Pangolin. Functions basically the same as the cloudflare tunnel it replaced.

The basic 4 dolars one? Or something extra?
