I have a LAN 10.0.0.0/255.255.252.0 (10.0.0.0-10.0.3.255) and want to separate clients (10.0.3.x) from the servers (10.0.0.x and 10.0.1.x) with a firewall in front of the servers. My problem is, i cant change address ranges nor subnets. Is this doable?
Edit: @HAL I looked up on vlsm and it looks exactly like what I need. Thank you.
