    Hardware or software firewall

    I have a Kensington Personal Firewall, which is a USB and hence external device, and which I gather is primarily intended for public wi-fi connections. Should I consider this to be a hardware firewall, or software? (And what's the difference?)

    It appears to work well with this XP configuration, but I have no idea if it is up-to-date, and I also have a software firewall in place, which is the reason for asking if I should have both.

    It's a hardware firewall, intended to protect wireless communication via an unsecured wireless network. You should be able to combine it with a software firewall. (Two software firewalls would be a bad idea).

    That device has the worst user reviews I have ever seen... Amazon , CNET. You must have received the good one. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    But I digress. To answer your question, I think the device drivers must include a software layer that redirects network traffic coming in on your wireless (or wired?) adapter to the USB stick or some software installed on your computer from the USB stick. If this redirect is defeated, then your device would not provide any protection. For that reason, although it sounds as though it works differently than a typical software firewall, it is not quite like having an independent device between the outside world and your network interface.
