I've got a router. NAT-urally. With certain proprietary engines on my machines, I don't dare run the risk of some bored 12-year-old in the Phillipines or Bulgaria or even Wales getting his sticky little fingers on a half million worth of code. This little Barricade allows 4 computers and a printer to network, too. Software firewalls are cheaper if you only have one machine, but even then I'd rather pay a bit more and have the extra security of being invisible. Carolly
