Looks like Trojan.Peacomm/Small.DAM, the "Video" trojan spammed recently, uses port UDP/4000 to communicate with a kind of peer-to-peer protocol.

There are some piece of software which is being used by travel agents to connect against Worldspan gateway websites (ticket booking purpose), which is not working if TCP/UDP 4000 is filtered. www.worldspan.com Best Regards, Thomas Aalborgen Taide Network AS Security Manager
