I have a network: 192.168.31.0/24 and computers on the network have static IPs 192.168.31.*
I'd like to segregate 5 of those computers (say 192.168.31.201 - 192.168.31.205) and put them behind a router/firewall (ClearOS) with firewall rules to only allow outgoing traffic to 192.168.31.0/24 and block traffic to the rest of the internet.
Can I setup a 192.168.31.192/28 within the 192.168.31.0 Class C network?
192.168.31.192 = Network
192.168.31.193 = Gateway
192.168.31.201 to 192.168.31.205 = computer IPs
192.168.31.207 = Broadcast
