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
This one of those questions I am overwhelmingly eqipped to answer, but only with the weird proprietary knowledge about software defined networking and microsegmentation that my job has endowed me with...
So I'll resist the urge to give you that overcomplicated answer and just say get a firewall like others have suggested.
I bought myself a mikrotik router to force myself to understand networking better. So I would really like to hear your over complicated answer that comes from professional needs. pretty please 🙂
Oh man, uh, here's a primer: https://mkomu.kapsi.fi/hipl/index.php?index=how
I am most familar with HIP, but there are ways to isolate hosts so that they can only talk to what you want them to talk to in a distinctly different way than a firewall. You could have three hosts (A, B, & C) on the same subnet where A can talk to B & C, but B & C cannot talk to each other. Likewise, A and C could have access to an Internet gateway, while B does not.
So far HIP is the only protocol I have seen for microsegmentation that actually works in an intuitive way, but I suspect Wireguard could be used to the same effect with some creative engineering.
After looking through it a little bit, it sounds like HIP is mainly used for verifying hosts' identities. It sounds like you'll still need firewall rules in order to create the scenario in your example, right?
Not if HIP is a part of your network stack (adding a waist). Unfortunately this is not a plug-and-play solution unless you have the budget for my employer's product, which is not priced for consumers.
I was just looking into this for myself. Can I ask what you went with?
Please don't, if it wasn't useful for me someone else might find it useful
