Using unmanaged switches to segment network, what problems?
Posted on 2012-03-15
I have 15 PCs and 3 printers going to a 24 port unmanaged switch. This switch is connected to router with 1 "internet" port and 4 Lan ports. The router internet port is connected to the cable modem and Lan port #1 from the router is connected to a port on the unmanaged switch. The router also acts as the DHCP server. Everything works fine, have internet access on all the PCs and everyone can see everyone elses PC on the network - which is the problem. I want to segment this network into 4 segments. I was thinking of just using 4 unmanaged switches, with one switch going to each of the LAN ports on the router.
1.) Will this work? Will it "isolate" each of the segments so the users on segment 1 let's say can't see the users on segment 2, but all segments and all PCs still have access to the internet.
2.) Will there be a performance hit?
3.) Is there a better way?
