What do I need to separate devices to its own no-internet network and still be able to communicate with within the house and outside? (Diagram provided)
(programming.dev)
Hello, I'm planning on creating a home server and getting some cameras.
I would like to have the server, cameras and all IOT devices be disconnected from the internet but still be able to access them within the house from different devices and maybe have limited access to them when outside.
Do I need a specific hardware for this? And what router would support this? I'm still in the planning phase but I'm looking for budget friendly solutions.
Thank you
You’d put a router with firewall capabilities in place of that cloud on the right. The devices you don’t want to have internet access will be put into a different subnet than your normal home LAN on the left. You’ll then make a “Deny all” rule so that the devices on the right can’t leave their subnet, with the exception of any explicit allow rules that you make.
This, pretty much - except you can do it with one router, the internet access point/gateway router.
Set up DMZ that can only access internal network, then set up a VPN and use that to access DMZ. If you need to, you can make a pinhole for one service or another, but you shouldn't need to because they're exposed to the LAN, and the LAN is accessible via VPN.
I suppose "DMZ" isn't exactly the right term, there, because that's typically somewhat exposed externally, but.. ..same idea, just no external exposure.
