Network Security: Firewalls, DMZ, etc
Hey again. As some of you know i recently setup a network for a friend, and enabled the internet to be shared by all computers attached to the network. The current setup utilizes no firewall or security, and i dont want to leave his static ip setup unprotected. I am thinking of using zonealarm, but dont know how i should set it up, ie what ports and things to block, as i know firewalls are a pain with some programs like aim or kazzaa. Should i just load it standard?
Also, i have heard about something called a DMZ, is this better then the firewall? What firewall do you reccomend? This isnt NASA were wrapping up, if it was a high risk type of thing i would order a hardware wall.
