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).
