I’m going to be overhauling my network over the next few months as I get ready for my new municipal fiber installation. I have a general idea of how to set things up, but I’m not an expert and would appreciate a few extra pairs of eyes in case I’m missing something obvious.

Hardware available:

  • Microtik Routerboard - 5 ports
  • Ubiquiti AP - AC-Lite; plan to add U6+ or U6 Lite once I get faster service
  • some dumb switches

Devices (by logical category; VLANs?):

  • main - computers and phones (Wi-Fi for now, I plan to run cable)
  • media - TVs, gaming consoles, etc
  • DMZ - wired security cameras, Wi-Fi printer (2.4GHz wireless g only)
  • guest - guests, kids computers

Goals:

  • main - outgoing traffic goes through a VPN
  • media - outgoing traffic limited to certain trusted sites; probably no VPN
  • untrusted - cannot access internet, can be accessed from main
  • guest - can only access internet, potentially through a separate VPN from main

Special devices:

  • NAS (Linux box) - can access main, media, and DMZ
  • printer - accessible from main, rest of devices on untrusted don’t need to be (I can tunnel through the NAS if needed); can potentially configure a CUPS server on the NAS to route print jobs if needed

Plan:

Router ports:

  1. Internet
  2. WiFi APs
  3. main VLAN
  4. untrusted (VLAN)
  5. unused (or maybe media VLAN)

WiFi SSIDs (currently have a 2.4Ghz and 5Ghz SSIDs):

  1. main VLAN
  2. guest VLAN
  3. untrusted - hidden SSID (mostly for printer) - 2.4GHz only

If the VPN causes issues, I would like the ability to move individual MACs to another VLAN (say, to media, or a separate, usually unused backup VLAN). Not required, just a backup plan in case the VPN causes issues.

This is my first time configuring VLANs, so I’m not really sure what my options are. Also, I’m not super familiar with Mikrotik routers (I’m not a sysadmin or anything, just a hobbyist), I just got fed up with crappy consumer hardware and wanted something a bit more reliable.

Does that sound like a reasonable plan? Is there something I could improve or suggestions you have?

Edit: DMZ is the wrong term, so I replaced it with “untrusted”. By that I meant a local-only network, so no Internet access. Ideally I could access these devices from my main network, but they can’t initiate connections outside their VLAN. However, that’s not necessary, since I can tunnel through my NAS if needed.

    I’m planning to get one at a local datacenter

    Ah, never mind then, ignore everything I said.

    So my plan is to set up a VPS and configure my own private VPN

    Unless I’m misunderstanding, you don’t need a VPS for this. RouterOS supports you enabling a built-in VPN server, which you can then connect to directly, you don’t need to set up a VPS or anything. Then you can just put allow rules in the firewall for traffic from the VPN subnet in to your main subnet, your NASs subnet, your camera subnet, etc. This is how I access my homes resources remotely, the only ports open to the Internet are the VPN ports on my CCR1036.

      You’d need a stable, publicly routable address, right? I’m not sure if I’ll have that, and I certainly don’t have it now. I can get it if I want, but it’s cheaper to just get a VPS.

      But yeah, if I end up getting an IPv6 address and my ISP doesn’t block ports, then yeah, that should work.
