Redesigning home network

Mon Aug 16, 2021 11:23 pm

Hello *,

i have the rare opportunity to rebuild/redesign the network for the house i'm living in, and i'm asking for some advice and nudging in the right direction.
I'd like to understand what's going on in my network and i see this as a journey to learn something (usergroup: enthusiast user ;) )
So after years of just adding devices and clients as they came in and having them in one subnet,
i now want to build the network from ground up: reasonable, expandable and manageable.
There are 2 rental parties, 1 cat6 to every room with some wallmounted PoE AP to provide local Wifi/guest Wifi.

I opted for the MikroTik netPower 16P (CRS318-16P-2S+OUT), because the patchfield and point of presence are in a somewhat dusty environment with temperature fluctuations, it has enough PoE ports and last but not least: 16 ports seem enough for my needs.

I based my first draw of the network design mainly on an Lab IP Address Plan ;)
the mikrotek-wiki and the threads Using RouterOS to VLAN your network and Mikrotik VLAN Konfiguration ab RouterOS Version 6.41
and came to the following layout:
Name	        VLAN	    IPv4
Management	10	           192.168.10.0/24
Guest net 	20	           192.168.20.0/24
Family 1   	30	           192.168.30.0/24
Family 1 IoT    31	           192.168.31.0/24
Family 2  	40	           192.168.40.0/24
Family 2 IoT	41                 192.168.41.0/24
Nextcloud       50                 192.168.50.50
There are 6 PoE AP (VLAN Management, devices 192.168.10.3 - 192.168.10.8 ), i want them to provide the WiFi networks
Guest
Family 1
Family 1 IoT
Family 2
Family 2 IoT
Icing on the Cake: I have an Raspberry with PiHole and unbound running, i won't go without and place it in VLAN Management to serve as adblocker/DNS for the whole house.

So my first Questions are:
  1. Is the layout reasonable? Any advices?
  • Is this doable with the choosen device?
  • I'm lacking some basics: The PoE AP feature one eth passthrough port. But when i connect that CAT6 wire to the CRS, am i loosing this physical port on the CRS to the WiFi or is it still assignable to another VLAN? i don't get it… :?

Thanks for reading this WoT and your thoughts.
D.

Good Morning,


Answers to you Question :

Question 1 : Is the layout reasonable?
If you really need to seperate your devices, VLAN is the way to GO

Question 2 : Is this doable with the choosen device?
Dont forget the MikroTik netPower 16P (CRS318-16P-2S+OUT) is a mainly a Switch , not a Router.
VPN's, Firewall, Queues, communication between VLAN's or to the Internet will go thru the "weak" CPU.

If you don't have Servers and your ISP is for exemple only 100 Mbits, it wont be a problem!

Question 3 : eth passthrough port. i don't get it…
It means your AP has 2 ether-Port

good evening,

thanks for your answers!
Question 2 : tbh, i didn't think about this, i choose the devices mainly because of the "environmental specs", guess i have to find out whether it is over/just-right/underpowered ;) . But i like the idea of having just one device with a power consumption lower than the two devices i have to power right now. well, i'll see.
