Comment on ELI5: How to put several servers on one external IP?

• greybeard@feddit.online ⁨1⁩ ⁨day⁩ ago

  I'll be honest, if you aren't planning on sharing with others, I'd recommend switching to something like wireguard to connect back into your house instead of exposing everything publicly. Some firewalls have wireguard built in, so you can setup the VPN easily. But then all you have to do is keep your VPN endpoint safe to keep your internal network protected from the Internet, instead of having to worry about the security of everything you expose.

    That’s a good piece of advice, but die to several considerations (extreme censorship interrupting VPN connections, family accessing the NAS, and some others) I cannot go that route.

      There's nothing saying you can't have ports forwarded for the NAS, and have a VPN for everything else. Censorship may be a problem, but those more often block VPN services like NordVPN, not protocols. So running your own is less likely to be stopped. That said, of course comply with local laws, I don't know where you live or what's legal there.

      If you really want multiple things exposed at the same time, you have two options(which can be used in combination if needed/wanted):

      1. A reverse proxy. I use caddy. I give it a config file that says what address and port binds to what hostname, and I forward port 443/80 to it. That works great for web content.
      2. Use custom ports for everything. I saw someone else walking you through that. It works, but is a little harder to remember, so good notes will be important.

      I still recommend against forwarding a lot of ports as a beginner. It's very common for software and web apps to have security vulnerabilities, and unless you are really on top of it, you could get hit. Not only does that put all your internal devices at risk, not just the one that was original breached, it also will likely become part of a botnet, so your local devices will be used to attack other people. I'd recommend getting confident with your ability to maintain your services and hardening your environment first.

        It’s not illegal to use VPN in my area, but connections are blocked on a protocol level, both through OpenVPN and Wireguard.

        I already managed to make caddy work, so, hooray!

        I also found a setting on my router that fully isolates certain devices from the local network. I want to put the server in there, so that the rest of my LAN is not under threat. I also want to figure out VLANs.

      What do you mean by blocked at a protocol level? You might give it a try on a random port to see what happens.

        I mean any connection through these protocols is just not working over the Internet. DPI equipment detects respective packets and cuts the connection.
