I am redoing my homes networking and I am looking for a firewall. I heard that you can install clear os on a server and use it as a firewall and a dhcp server. So i was going to install it on a rack in my server cabinet. does the server need to have a wan port and a lan port? Or how does the server get connected? So, so far its the cable modem into the clear os firewall and then into my switch. Is is possible to use the clear os server as the dhcp server for the whole house? From the switch I am going to connect the rest of my servers, and the rest of the house. I was going to connect two wireless routers for my house. Would that work with the clear os server?
