need to prevent DOS attack/Flood on all udp ports
Hi i opened game servers and i faced DOS attack from others using udp flood script on their vps,
i used to protect my vps from tcp flood ddos-deflate script based on iptables firewall, but still udp not protect
i made some test DOS attack on my game server using udp flood script
flood.pl < IP > < Port > < Packages > < time >
if i set Packages to 90 the only selected port down, but if i set Packages to 1024 all servers get down/timeout
so if there is any iptables command/rules to limit Packages & connection per ip on udp port please ?

How about instead of opening another thread you go read the existing one where this was already answered for you by several people: https://www.lowendtalk.com/discussion/110358/how-can-i-prevent-ddos-atack-on-my-vps ?
You need to purchase a service with DDOS protection as part of the service, you will not be able to handle this with iptables, period. There is a reason DDOS services exist and it is because of these types of attacks against game servers.
Cheers!
