How about blocking 225^4 on all your routers?

Thank you,

Subject: [SECURITY] Blubster Traffic

So, our network is getting flooded with Blubster traffic.  It seems that
whenever a user does a search through Blubster, it connects via
UDP/41170 and scans local IPs and also hits 255.255.255.255.  The 255
traffic is killling the network.  Our Packeteer seems to be blocking
some of it, but not completely.

Any ideas?
