How to Limit DNS Request per ip source ?

[Gaurav Kansal]

Dear All,

 

I want to limit the dns request per ip source through iptables.

 

I tried the following commands, but unfortunately didn't succeed. 

 

-A RH-Firewall-1-INPUT -m udp -p udp --dport 53 -m state --state NEW -m
recent --set --name DNSQF --rsource

-A RH-Firewall-1-INPUT -m udp -p udp --dport 53 -m state --state NEW -m
recent --update --seconds 60 --hitcount 5 --name DNSQF --rsource -j DROP

 

 

If anyone is using iptables for limiting DNS Query per IP, then pl. help me
out.

 

 

Thanks and Regards,
