Data iptables rules (ubuntu)

Could someone help me with writing rules for iptables?
I need a dos attacks protection for a game server.
port type udp
ports 27015:27030
interface: eth0
Accept all packets from all IPs
Chek if IP sent more than 50 packets per second
Drop all packets from this IP for 5 minutes
I would be grateful if you can write whole ready rules for copy/pasting, because im noob at iptables.
