switch vs router
switch vs router
Avoid wasting effort on redundant hardware here. In an offline setup, do you require a router if each device has its own IP address? Or is a switch sufficient? I understand both managed and unmanaged options exist. Your current setup uses a fiber converter, router, and 24-port dumb switch with two wireless APs for a local network. You need a file-sharing and security camera environment that doesn’t require internet access. Should I recommend buying a simple switch or opt for a managed model? The 6pcs and 28 cameras you mentioned are available at a good price for 48-port gigabit switches with 10GB uplink.
If you're open to assigning static IP addresses, you won't need a router for every device to connect. I've noticed some cases with WebUIs like IPMI on servers where they fail without a Default Gateway, but if you don’t run into those issues, it should function as expected.
Only a router is required to transmit data between two distinct networks. Assigning static IP addresses within the same network (such as 192.168.1.1, 192.168.1.2, 192.168.1.3...) eliminates the need for a router. A switch will suffice in this scenario.
Networking is far beyond my expertise. Each device needs a dedicated static IP. I’m not sure what VLANs or managed switches are, but I’ll figure it out.
It varies based on your needs. For a home setup, use a NAS and a router. In an enterprise environment, both are useful: a switch for internal tasks and a router for Wi-Fi. Just keep in mind: I didn't suggest using a switch alone. If you need a switch, add a router. You can have a switch, but it's not ideal without a router. A router is the best choice overall. Using only a switch will make things more difficult.
That approach could function, but be aware you disrupt the isolation when connecting the server to the network. I suspect you're aiming to keep these systems disconnected for security or privacy reasons. Once connected, it might create indirect access points for other devices and internet traffic. Depending on your priorities, it's wise to carefully consider this before linking the server. No, a router isn't necessary here. Indeed, you can use a switch that only interfaces with air-gapped devices.
