Thank you very much to all of you. I've been doing a little work on this first reading the IPTables HOWTO and its man pages. Now I understand a little more how the firewall works :-) I left open only port 80 (for my web page) and updated all Apache's files. To me it sounds like somebody is scanning my provider's net for vulnerable windows PC's. Thanks again! - Joaquin! Ing.
