Using a GUI or other such as Shorewall, it is easy to 'blacklist' them 
entirely or just blacklist for that port/protocol. You can also have it 
silently blocked to avoid choking your logs.

If you're still stuck, email the IP range and I'll plug it in here to 
see what iptables gobble-de-gook is generated...


Cheers,
Martin
