Hello everyone,
I have the following scenario. A building with 4 floors, each floor with its own switch, firewall and WAN IP.
I would like to replace the whole thing with one MikroTik router.

The plan was for each floor to have a port and its own subnet. So, ether1=WAN, ether2=192.168.1.1, ether3=192.168.2.1, etc. separeted with appropriate firewall rules.

But I'm wondering whether VLAN would be a better solution here? Some of the switches are unmanaged. Would that even be possible?
What would be the best practice?

Thanks.
