I have a nextcloud instance being hosted from my home network. The URL associated with it points directly at my home’s IP. I don’t want to host the instance on a VPS because disk space is expensive. So, instead, I want to point the URL at the VPS, and then somehow route the connection to my home’s nextcloud instance without leaking my home’s ip.
How might I go about doing this? Can this be achieved with nginx?
EDIT: Actually, not leaking my home’s IP is not essential. It is acceptable if it is possible to determine the IP with some effort. What I really want is to be able to host multiple websites with my single home IP without those websites being obviously connected, and to avoid automatic bots constantly looking for vulnerabilities in my home network.
You can set up nginx to do reverse proxy to your home IP, and then limit the traffic on your home IP to the VPS IP.
You can also setup a wireguard VPN between VPS and your home machine, so the traffic between VPS and your hoke machine is encrypted.
For DNS you just point to the VPS, and manage connections there, and on home network allow only VPS IP to connect. Then manage your security on the VPS.
Thanks a lot! This is kind of the configuration that I have converged to, with nginx and WireGuard. The last thing I need to set up correctly is for the SSL handshake to occur between the client and my home server, and not between the client and the internet-facing VPS, such that the information remains encrypted and unreadable to the VPS. The two strategies that I have seen can do this is SNI routing with nginx or to use stunnel. I still have not been able to set up either!
In that case, you’re better off just using the VPS machine as port forwarding port 443 to your home machine’s wireguard IP address and handle the SSL/TLS termination on the home machine.
This way all HTTPS traffic will be passing trough the VPS and being decrypted on your home machine, and encrypted data will be sent from your home machine back to the client. Anyone gets in or sniffs traffic will see encrypted traffic. Plus it’s already sent over encrypted VPN network. To really see what’s happening, they need to get into the machine and technically could use the wireguard private keys to decrypt the traffic, but they will still see the encrypted HTTPS traffic. So you’re good, technically.

This is what I would like to do! I was trying to handle the SSL termination ‘automatically’ by simply forwarding the connections to 443 of my machine’s wireguard IP using nginx, but I did not manage to get it to work. That’s when I found that I need to use something like ‘stunnel’ to handle the SSL termination. But I think that you may be suggesting an even simpler method of using port-forwarding instead of the reverse proxy. I am not sure how to achieve that, I will look into it using these terms.
You can setup HTTP reverse proxy on your VPS. You’ll need to point the domain to your VPS for that to work.

That’s easy. You have two ways:
- Host the websites under different paths in the same domain. If your websites are static this is fine, but if they are “services” this may not be feasible (and could be very complicated if it is feasible).
- Host them under different sub-domains. The way it works is you create a bunch of NS records in your DNS, pointing the subdomains to your root domain, and setup one “virtual host” for each of them in your HTTP server. Both Apache and Nginx have the ability to match virtual host by domain name.
to avoid automatic bots constantly looking for vulnerabilities in my home network.
I’m not sure how you would eliminate bots by separating the websites though.
I currently use reverse ssh tunnels to my vps. The vps runs nginx proxy manager and through that way I can tunnel specific ports to my vps, whereas with wireguard all my internet traffic was rerouted to my vps. I didn’t like that because of bandwith limitations so that’s why I chose this aproach
ssh tunnels
There are so many concepts to learn about! But if the SSH tunnel improves the the available useful bandwidth compared nginx/wireguard, it might be worth looking into it too. Thanks!
You could do the VPN / VPS option with a reverse proxy like nginx proxy manager. Or, you could use Cloudflare tunnels. Worth noting that from a privacy perspective you’d be putting a lot of trust in Cloudflare. The same is also true for whoever you pick as your VPS provider
Thanks! Wireguard was suggested as a VPN, and I am currently playing with that.
