Reply #12: It's the "New Firewall User Syndrome"

[TahitiNut]

I've seen this repeated and repeated over the years as more and more people connect to the "always on" broadband and DSL internet connections. The fact that your fiewall is detecting, blocking, and logging such traffic tells you it's working. In 99.999% of the cases, such traffic poses absolutely no problem, even without a firewall. If you're not running an internet server, you haven't inadvertently installed a Trojan Horse, and you have no buffer-overflow exploit vulnerabilities in your socket software, there's nothing to be overly concerned about.

From the beginniing of (internet) time, folks have "felt" their way around the net ... scanning for active systems and mapping the net. It wasn't until the Great Luser Flood of the early 90s that this exploration activity was of much concern to anyone.
