Three networks behind one

RouterOS Beginner Basics

Hi all,

We share a shared server, NAS and internet connection with some neighbors. This is increasingly becoming a problem because of all the smart gear. TV’s, apple TV’s, Sonos, etc. I don’t like it when the girl next door starts her music on my Sonos…

That’s why I would like to have three different networks for ourselves and two neighbors, but we all need te use the same NAS, server and of course internet gateway/router. So I was thinking of 172.17.1.0/24 for the NAS, the server and internet, 172.17.2.0/24 for my house, 172.17.3.0/24 for neighbors 1 and 172.17.4.0/24 for neighbors 2.

I have a RB 2011UiAS, with software version 6.34.3

I have separate cables for all different networks, leading to gigabyte switches for each separate home/network. My internet gateway, NAS and server are also on a separate switch.

Is there a way to configure what I want?

By default, Eth1 is for WAN, Eth2 is Lan, then Eth3 to Eth-10 is a slave port to Eth2.

Edit Eth3 to Eth10 and set master-port to none.

Now each port is it’s own network.

Go to IP > Addresses and set your static IP for each interface, 172.17.x.1/24
Next go to IP > Pool and create your DHCP pools for each network.
Then go to IP > DHCP Server and create a DHCP Server for each interface.

The hostnames of your NAS won’t resolve when not on the same LAN unless you use DNS or WINS. Or just refer to your NAS via IP address. If you use DNS, you can configure the hostname in IP > DNS, then click the “Static” button. That’ll allow nas1 to resolve to it’s IP.
