Hi Michel,

Because I am a newbie with Arnos firewall, I can't give advice for the

extremly large.

Try to find out the top networks by whois.arin.net, and you are able to 
block by /8 subnets. I did this with success to block ssh from Asia with 
just 41 subnets. I'am quite sure that my list is not complete, but here 
you are:
