I wouldn't be too concerned about having your ports sniffed once in a while. Far from someone trying to access your specific 'puter it's most likely some gob$hite kode kiddie with an off-the-shelf scanner trawling for what they can find. I admin a site and sometimes amuse myself watching all the mappets bouncing off our firewall, it happens too often to do much more than keep yr shields charged and up to date. Don't sweat it (unless u keep valuable secrets on a home pc in which case u deserve to be cracked), don't bother trying to trace them, do keep yr shields up.
