Hmmm.. Funny that... And just how do you improve the security on say, a laptop that uses WiFi, Dial-up and Ethernet connections? Pretty hard to squeeze a hardware based firewall in there... And isn't it interesting that the Linux community has headed down the same path, since most recent distro's of Linux contain some form of "software" firewall (ipchains, iptables, etc). OK, so the Windoze community are often bleating, but that's more to do with their lack of technical knowledge, than the failings of software firewalls. Then again, hardware firewalls tend to have all the same failings as software ones, except for one thing, the underlying "OS" tends to be known quantity to the vendor (the likes of CheckPoint often being the exception, but Oh, that would make it a software firewall... :) At least if Windoze users are installing firewalls (software or otherwise), that's got to put things in a slightly better light than before. Oh and I don't include the Windows Internet Connection Firewall in any of the above statements. A "firewall" that doesn't account for outbound and allows any M$ application to do whatever it likes (in terms of opening ports) without telling the user, isn't a firewall at all. </rant> Later'ish Craig
