Or is the threat a mirage? Maybe yes, maybe no. If there are lots of unprotected systems that are on 7x24, that's a problem. A DOS attack with 50,000 PCs scattered all over the network is *much* nastier than anything that can be mounted from even a large university. I don't know how good the "firewall" applications are either. There are some "DSL/Cable routers" that have built-in firewall functionality, and seem pretty good. Since they are nearly plug-n-play for a small LAN of windows boxes (i.e. - just configure the windows boxes as DHCP clients, and you're done), one can hope they become popular for sharing network connections, etc. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
