I try this commands
Code:
iptables -I INPUT 2 -p udp --dport 7777 -m state --state NEW -m limit --limit 3/sec --limit-burst 3 -j ACCEPT
 iptables -I INPUT 3 -p udp --dport 7777 -m state --state NEW -m limit --limit 3/sec --limit-burst 3 -j ACCEPT
 iptables -I INPUT 4 -p udp --dport 7777 -j logreject
 iptables -I INPUT 5 -p udp --dport 7777 -j logreject

Code:
iptables -N rate_limit
 iptables -F rate_limit
 iptables -A rate_limit -p udp --dport 7777 -m limit --limit 3/sec --limit-burst 7 -j  i with  ACCEPT DROP

Yes, you shold press Save Firewall, this way your script gets saved inside the firewall script and gets executed every time that firewall service is restarted.
