My network is being flooded with UDP packets, Denial of Service
attack, soucing from Cloud flare and Google IP Addresses

but, until nancy drew walks the attack back upstream step by step, you
really do not know it's coming from clodflare or gobble.

the destination in my network are IP prefixes that is currnetly not
used

them it should be pretty easy for your upstreams to filter without
doing damage to goodput.
