If you don't need UDP, disallow it to your entire network or to the /xx where such is applicable. We have basic filters like this with our carriers upstream and have prevented several Gbps of traffic from ever hitting our filters as a result.

What does application use 8.8080,0 port for the proper purpose?I've seen newer BitTorrent clients do this (UDP is supported, and the port can be arbitrary). Cheers, Michael Holstein Cleveland State University
