I'm CompTIA A_+ certified studying to get my Security + and would like to know how to form a network appliance for my home network. Can I do this by using Software? I'm also confused on Network Appliance, is a Network Appliance hardware? (Like a router) is basically just a router that filters information and packets from a LAN, like a Firewall? I looked it up and researched it but I do not understand it enough to practice implementing it for my own knowledge.
