Answer to February 2006 Reader Challenge

The reader is incorrect. The router's firewall blocks suspicious transmissions from traveling past the firewall to any connected devices, whether they're computers or switches.

The February 2006 Challenge

A reader sent me the following message: "I've read several of your books and you always neglect to tell your readers about a dangerous security problem. When you wrote about router firewalls, you didn’t specify that the router firewall only works if the computers are connected directly to the router. If you connect the computers to a switch, and then connect the switch to the router, you MUST install a firewall on each computer because the router’s firewall won’t work."

Is the reader correct? Amplifying your answer beyond "Yes" or "No" will enhance your chance for a prize.

February 2006 Reader Challenge

Solve this month's Windows Client challenge, and you might win a prize! Email your solution (don't use an attachment) to challenge@windowsitpro.com by February 15, 2006. You MUST include your full name, and street mailing address (without that information, we can't send you a prize if you win, so your answer is eliminated, even if it’s correct). I choose winners at random from the pool of correct entries. I’m a sucker for humor and originality, and a cleverly written correct answer gets an extra chance. Because I receive so many entries each month, I can't reply to respondents, and I never respond to a request for a receipt. Look for the solutions to this month's problem right here on February 16, 2006.
