"Theoretical" Network architecture question

Hi All,

First of I am new to networking. So far I am really liking the Mikrotik devices and OS. I have been playing around for a while with OpenWRT etc, but now I would like to venture into more advanced topics. Therefore I have purchased 3 Mikrotiks, hEX, hAP AC and hAP AC Lite.

I would like to try and setup the following:

  • 3 VLANs
  • Vlan 10 - Management (untagged) - No DHCP - Internet - 10.1.1.0/24
    • Vlan 100 - Home - DHCP - Internet - 10.1.2.0/24
    • Vlan 200 - Guest - DHCP - Internet - 10.1.3.0/24
  • Use both 5G and 2.4G AP for Home Vlans on both hAP AC and hAP AC Lite
  • Use 2.4G virtual AP for guest for guest vlan
  • hAP AC will connect to hEX through eth2
  • hAP AC Lite will connect to hEX through eth3
  • hEX eth4 will connect to a standalone switch connected only to devices for home vlan
  • hEX eth5 will connect to a RPI with DNS server (piHole)
  • All DNS should go through piHole
  • eth5 on both hAP AC and hAP AC lite should support untagged management

My main questions:

  • Is it possible to have the DHCP for VLAN 100 Home hand out IP addresses to all client connected or should they have different ranges?
  • Same question for the IP addresses for VLAN 200 Guest?
  • In a early semi working setup it was possible to use winbox on the eth5 of hAP AC and also see the admin interface of the hEX. However on the hEX I could only see the hEX interface would this be a routing problem?

I have added a network diagram of what i would like to achieve as attachment.

Any input would be highly appreciated!
