Personally, I don't like the idea of script kiddies and hackers knocking on the back of my Ethernet card, protected only by a piece of software (like ZoneAlarm or Tiny).
I run the Linksys firewall, several computers attached to it, and Norton Personal Firewall on my main machine. Norton PF blocks cookies, JavaScript, and ActiveX while you're browsing. The Linksys gets everything else.
BTW, once you go on cable or DSL, hackers will be trying to scan/hack your system all day long, every day of the week. Using the above for more than 1 1/2 years, I've never had a problem.
But a few weeks ago BellSouth (my provider) sent me a letter saying that they were going to start offering routers to their customers that needed more than one hookup. The letter was worded as if you have to pay extra if you rout the connection to more than one computer. Even if you buy and install your own equipment to two 'puters.
Can they do this?
1. Practically, meaning, can they tell if I install my own router.
2. Legally, I don't remember seeing any thing like this in my original agreement. (other than terms subject to change at any time, blah, blah, blah)
