Hardware firewalls
I currently run one PC with Windows XP Home with a second one arriving shortly. To take advantage of my Telewest broadband connection I plan to instal a wireless router and think I understand how to do this. At present the existing PC has AVG anti virus and a Zone Alarm firewall and I would plan to do the same with the new one. However I keep seeing references to the router having a hardware firewall. Could somebody explain how this works and whether I would still need Zone Alarm or does the hardware replace this.
Thanks
