I was using my computer off-line when the phone rang and through my speakers I heard the modem pick-up & a computer/fax signal.
(I have a Dell Win. XP SP-2, with a dial-up connection and CA eTrust Personal Firewall.)
When I checked the eTrust logs, I found that several inbound communications had been blocked including two attempts made (at about the same time as I heard my modem pick up) originating from DNS source: "dedicated67.fastcolocation.net".
I was concerned when I heard my modem respond without my log on. Apparently, the etrust firewall blocked it, but why was another computer able to call my machine and have it pick-up the phone? Is this a symptom of a greater security threat?
