Hi everyone!
I’m looking into self-hosting, and I currently have dynamic DNS set up to point to my home IP.
My question: is it worth getting a dedicated IP through a VPN?
I’m pretty technically savvy, but when it comes to networking I lack practical experience. My thought is that pointing my domain to a dedicated IP and routing that traffic to my home IP would be safer - especially if I only allow traffic on certain ports from that IP. Just curious if that idea holds up in practice, or if it’s not worth the effort.

A fixed IP does make things easier at first, but I fail to see the value on that for personal use. Nothing a reverse proxy and DDNS can’t replace.
I purchased a domain, use dynamic DNS for it, and point my sub domains to an NGINX proxy server that handles where each points to.
Nothing has access to anything in my network from the internet (all ports are closed on my PFSense), other than Wireguard, and I just VPN into my network when I’m not home.
It was scary when I started, but figured it out in a couple of days. Take into consideration that I’m not even mildly smart, so it should be fairly easy for anyone.
Get into furoms, ask around, watch tutorials, you’ll be up and running in no time.
Good luck.

Thanks for the reply!
So the NGINX server hosted outside your network, then? And then reverse-proxy that into your home server?
Honestly, I feel like NGINX is a bit overkill for my situation, since I’m not expecting to have a lot of traffic. I could be wrong, though.

Their setup sounds similar to mine. But no, only a single service is exposed to the internet: wireguard.
The idea is that you can have any number of servers running on your lan, etc… but in order to access them remotely you first need to VPN into your home network. This way the only thing you need to worry about security wise is wireguard. If there’s a security hole / vulnerability in one of the services you’re running on your network or in nginx, etc… attackers would still need to get past wireguard first before they could access your network.
But here is exactly what I’ve done:
Now I can just turn on my phone’s VPN whenever I need to access any one of the services that would normally only be accessible from home.
P.s. there’s additional steps I did to ensure that the masquerade of the VPN was disabled, that all VPN clients use my pihole, and that I can still get decent internet speeds while on the VPN. But that’s slightly beyond the original ask here.

Nginx isn’t for security it’s to allow hostname-based proxying so that your single IP address can serve multiple backend services.

No, it’s inside the network. Once I’m inside my network via the VPN, the proxy server routes to the service I want based on the subdomain instead of using the IP and port as the address.
This can also be useful if, instead of going the VPN route, and you choose to go the CDN tunnel (for example, Cloudflare) way. I actually started with a tunnel via Cloudflare, but after some digging, I don’t trust them anymore. Having a tunnel allows you to close all ports coming into your network, but at the expense of having to trust the tunnel provider, and I don’t trust many companies out there.

No, the nginx runs inside your network. It’s the “entry point” to it and it proxies all requests to your respective services.
