Last night, from 22:51:49 until 23:31:38 (CDT)there were 63 Low Priority Alerts via the Kazaa Service to my Port 1214 for a Local IP which was NOT mine. I know my machine's IP. I reported the address of the other IP to my ISP later last night (anonymously). My ISP provides DSL service via a LAN. I have never used any Kazaa Service before either! I did a "whois" on that IP. It belongs to someone working in the corporate division of my ISP. I now suspect he was using my computer as a proxy. How else can I explain how a completely different Local IP showed up in my VisualZone Log? (Please note: I've never had a different Local IP in my Zone Log before.) What I want to know is how do I protect my machine from being used as a proxy, especially when it's without my knowledge? Any help will be much appreciated and perhaps help others with the same problems. I would like to prevent further occurences. Thanks.
