Sure, reading through the feature set of Windows Vista is one way to get a taste of what an upgrade will do for your life, and reading "expert" reviews of the operating system and its minutiae certainly add an additional bit of insight not conveyed on the box alone, but one aspect of Vista is facing some serious criticism from a skeptical reviewer. In Microsoft's latest OS, the "Windows Firewall" boasts about offering up two-way protection -- that is, blocking both incoming and outgoing data -- but after careful analysis, it's apparently not that cut and dry. CNET's Robert Vamosi has noticed that the system does a fair job of blocking malicious content from reaching your PC, but when inspecting the outgoing blocker a bit more carefully, it appears that you're covered from moment one, as it's turned on by default -- or not. Interestingly, having this section of the firewall enabled does absolutely nothing for your protection, as in the default configuration "there are no block rules, only allow rules," which essentially means that it's capable of blocking, but until you specifically enable blocking rules for specific programs, you're exposed. Microsoft's reasoning is that maximum protection would cause new users to see a warning with every single application they launched on their PC, causing both frustration and a desensitized view of the firewall itself, and while we can certainly sympathize with how annoying those pop-ups would be, CNET feels that this excuse stems more from Microsoft's handiwork in crafting the OS more for enterprise use and less for novice "home" users. Nevertheless, knowing that your outbound firewall is likely wide open should help more than a few of you close any potential holes in your fortress, and be sure to hit the read link if you secretly enjoy hearing Vista take a severe tongue-lashing.

It looks the barrage of draft-spec 802.11n gear being released isn't slowing down anytime soon, and helping the yet-to-be-ratified protocol gain more ground is SMC. Making good on its promise to ship draft-N gear, the networking company has reportedly launched the Barricade N, which utilizes "multi-antenna MIMO support" to connect at rates of "up to 300Mbps," sports a four-port Ethernet switch, and can automatically prioritize duties such as music / video streaming to keep things skip-free. Complementing the new router are pre-N versions of the company's EZ Connect CardBus and PCI wireless adapters, which will give your lappie or desktop the ability to take advantage of the ultra-speedy 802.11n standard. All three devices are purportedly available right now, with the Barricade N selling for $120, the PCMCIA adapter demanding $80, and the PCI card costing $90.

Considered upgrading your DSL/Cable modem connection lately? Been wondering just how much of that high speed Internet connection you've been using? (Or if one of your kids or housemates is eating up all the bandwidth with BitTorrent again.) Today we'll show you how to use some handy free tools to keep an eye on your precious bandwidth. Hey, it just might save you from having to bleach your eyes if you walk in after Bob's download finishes.

Network appliances don't always offer all the firewalling features a user needs -- you know, the advanced port blocking and security procedures we'd like to keep our little home network fiefdoms secure. In today's How-To we'll show you how to build a firewall out of an old PC with a live Linux CD and some spare ethernet cards. It's the perfect use for that machine with the dead hard drive (or no hard drive at all).
