Can I isolate two wired subnets?
I can handle simple network setups but have no experience yet with what I want to do: I want to, behind my comcast business gateway, set up two different wired subnets which cannot access each other. How simple (or not) is this? Can I just plug a second switch or router into a different plug on the back of my comcast gateway and expect them to be isolated from each other? How about if I have two routers, set one as, say, 192.168.1 subnet and the other as 192.168.2 subnet. Would they then be isloated from each other?
