If anyone is thinking about getting your masters degree...don't. J/K. After a long hiadus I am back. I am getting a double masters degree at Arizona State...now that my p-roject is over I have returned. I recently switched over to cable internet. I have two systems. There is one downstairs that the modem plugs in to. There is also one upstairs that is connected via a wireless router. My question is, would it be possible to use a software firewall along with the router on the upstairs computer. I realized there are ports that are not stealthed. Also, I like knowing what applications are able to transmit. I have tried simply configuring the router (to at least p block the open and closed ports) but to no avail. Any information would be greatly appreciated.
