Re: udp flood protection
It is in the nature of UDP that essentially all the processing is up to
the receiving application. So the definition of "flood" depends on how
much your application can cope with. Contrast TCP SYN flood attacks,
where the "flood" arises because it fills up a connection table managed
by the kernel.
Checking IP addresses of incoming UDP packets isn't going to be enough,
since any eavesdropper can determine which addresses you're
communicating with and spoof packets with those addresses.
