The Mitel/E-Smith Server does an excellent job of filtering almost all inbound connections, however you must keep in mind that all peer to peer solutions ( kazza, morpheus, Direct connect) orginate on the private-side (desktop) going out through your Mitel/E-smith box to an external server to facilitate indexing and routing requests of mp3's and appz. The only way really to eliminate the problem is to remove the kazaa client from your desktop machine or configure it to not start as a service on your PC. BTW trojans work the same way

Hmmm strange analogy..., Antivirus and Antitrojan tools should be on your PC too.
