I have an openwrt router at home which also acts as my home server. It’s running a bunch of services using docker (Jellyfin, Nextcloud, etc.)
I have set up an SSH tunnel between my openwrt router and VPS and can access jellyfin successfully.
I understand that I need to set up a reverse proxy to access multiple services and have https.
But I’m confused if I should set up this reverse proxy on the VPS or on the router itself. Is nginx the easiest option? Should i add subdomains in cloudflare for every service?
Pease don’t recommend vpns since they are all blocked where i live (wireguard, tailscale openVPN, etc.) I’m limited to using ssh tunneling only.
Thanks
I should also add something that lots of beginners miss.
The reverse proxy does not care what the domains that you define in it actually resolve to. It receives the domain name as a HTTP header which is completely at the whim of the client. As long as that domain name matches one of the domains defined in the proxy, it’s all good.
You can successfully connect to a proxy with a domain name defined in the domain owner’s DNS, or you can make up your own DNS that says whatever you want, or you can define any domain->IP association you want in your hosts file, or you can simply use curl or wget to connect directly to the proxy IP and lie about the domain in the HTTP headers without having it resolve in any DNS.
This means that yes, the proxy will happily serve your “private” *.local.example.com services to someone connecting from outside your LAN. All they have to do is figure out (or guess) your subdomain names. You need to add IP restrictions in the proxy (default deny from all + lan ip mask explicit exception) if you really want those services to be restricted to the LAN.
DNS is not security, it’s a public service that maps domains to IPs.
TLS is only security in the sense it protects the connection en route from eavesdropping, but it doesn’t restrict access.
Thanks I understand the theory behind this but I can’t get it to work.
I have a jellyfin.mydomain.com subdomain pointing at my VPS ip. On my home server I have Nginx Proxy Manager listening to 192.168.8.1:8998 (http) and 8999 (https) From my home server I forward port 80 from the VPS to local port 8999 like this:
ssh -R 80:127.0.0.1:8998 root@vps-ipThen on npm I define a proxy to localhost:8096 (jellyfin) for any traffic sent to jellyfinn.mydomain.com.
But I can’t access jellyfin remotely.
Check all the steps individually then:
- check that the ip resolves to the VPS IP at the location you’re testing this
- set up the tunnel to bypass the proxy (connect it directly to jellyfin)
- check that jellyfin works directly
- check the proxy directly, with curl connected to the proxy with the header “Host” set to the domain
- check that the VPS firewall didn’t block port 80
- normally you wouldn’t be able to forward port 80 with a normal ssh user but I see you’re logging in as root so it should be working
If you are new i recommend “Caddy V2”
It is by far the easiest.
Wait with Nginx until you’re better. (and even then, use linuxserverio/swag instead of nginx)
Caddy was exactly what i needed. It magically solved the problem…
As someone who used caddy over years, I can’t completely agree.
Caddy has some downsides (nextcloud needs special setup for example) and not everyone is familiar with writing a Caddyfile. (Json)
For someone new I would recommend “nginx proxy manager”. Easy to install with docker and self explained through GUI.
i actually think NPM is more confusing. 1: there are practically always already finished Files for Caddy V2. Most of the times directly in the Repo of the Project. A lot of Devs use Caddy themselves. 2: NPM exposes a lot of Options additionally. This can confuse newcomers. With Caddy, all these extra options are invisible. you just write and see “reverse_proxy jellyfin” and that’s it.
Completely agree. I haven’t used NPM since I started self hosting a few years ago, but I was never able to get it to work right. I ended up using apache2 as it was pretty well documented everywhere. Moved to caddy v1 when I found it as the config is so easy to write and understand. Moved to v2 when it was released and had no issues. Their forum is incredibly helpful if you run into any issues. At this point its a “relatively” mature platform and most projects I’ve setup have an example config (usually just 1 or 2 lines because that’s all you need).
Swag was my nginx introduction, and it was mildly confusing because I ran it on docker and didn’t understand how to edit configs at the time. I’d recommend following a guide instead of winging it like I did 😅
I know this isn’t what you asked but I would move any hosted services outside of DNS to a separate device.
Check “boring proxy” On github easy to install and configure and does https for you

Maybe look into https://nginxproxymanager.com/ it makes it quite easy to set up.
There are pros and cons to keeping the proxy on the VPS or at home.
If you keep it at home you will have end-to-end encryption from the browser to your home server. Downside, you will not get the IP of the remote client, just the IP of the router, so you won’t be able to do IP blocking or diagnostics.
By putting the proxy on the VPS and decrypting HTTPS there you can add remote IPs to connections but you have to keep the TLS certificate on the VPS so in theory someone could mess with it.
A third option is to run a minimal passthrough proxy on the VPS that adds the remote IP to the HTTPS connections without decrypting them. To do this you must use the same proxy at both ends (home and VPS) and both must have the PROXY protocol enabled.
I would suggest doing just proxy at home to start with because it’s simpler. If you want a GUI use NPM (Nginx Proxy Manager) it’s super easy. If you prefer a proxy where you write config by hand use Caddy.
After you have it working at home you can consider adding the one on VPS and enabling the PROXY protocol. Although I’m not 100% sure Caddy supports it, look into it. You may have to use Nginx in both places I’d it doesn’t.
You do not need to add subdomains in DNS, not unless you want to. You just need one domain to point an A/AAAA record at the VPS public IP, then you can make the subdomains a wildcard CNAME pointing at the base domain. So A/AAAA example.com -> IP, and CNAME *.example.com -> example.com. Or you can put the A in another domain and point the CNAME at that.
When requesting TLS certificates it’s the same thing, you never ask for explicit certificates for each subdomain, you just ask for one wildcard certificate for *.example.com. Aside from the obvious benefit of not having to add and remove certificates every time you add or remove subdomains, there’s the not obvious benefit of not having bots learn about your subdomains (certificate application are public records).
The subdomains do not need to resolve in DNS for this to work, the certbot verifies that you own the domain by using a DNS API key to create a temporary TXT on example.com; as long as that works it won’t care what’s actually defined in there.
How can something like Tailscale be blocked?
Unfortunately, Deep Packet Inspection does this as Tailscale/Wireguard does not encrypt trafficMy bad, it encrypts traffic, but I mean easily readable signature
Wireguard, like all VPNs, definitely does E2E encryption. What would be the point of an unencrypted VPN?
https://www.wireguard.com/protocol/
Looks like wireguard encrypts traffic to me.
It’s easily detected by firewalls in China and Iran.
Interesting, because Tailacale doesn’t use any special ports. How would that be detected? And could you maybe use Headscale on a dynamic port to circumvent that?
Wireguard is blocked at protocol level no matter which port you use. Tailsclale uses wireguard. Haven’t tried headscale yet.

It definitely encrypts the traffic, the problem is that it encrypts the traffic in a recognizable way that DPI can recognize. It’s easy for someone snooping on your traffic to tell that you’re using Wireguard, but because it’s encrypted they can’t tell the content of the message.
Firstly…why are you routing your home stuff through a VPS? I’m confused on what is happening here.
If you just want to access your things remotely, setup a VPN server on the router, and connect to it that way. You also dont need a reverse proxy or SSL if you’re already accessing things over a secured connection. Where did you get this info from?
Please read the post man, all VPNs are blocked on the protocol level
That’s not how VPNs work, you can’t just “block all of them”. I think OP just needs to use a pure-TLS VPN solution (like SoftEther) or an obfuscated one like shadowsocks/obfs from a not-super-well-known provider (or self-host it on a VPS/etc.) and they should be golden.
They sniffing the traffic with DPI and block vpn tech on protocol level, so easy detectable things like OpenVPN, Wireguard and Tailscale doesn’t work anymore
I understand, that’s why I suggested some non-easily-detectable solutions.
That was added later, obviously. Even still, you don’t need a VPS for this. This is overly complex .
If SSH works, just forward ports and be done with it.
I don’t want to remember port numbers. I’m trying to give each service its own subdomain.
Beggers CAN be choosers, apparently 🤦
