remove a particular iptables rule
 

Dear Friends ,

I have to run the follwoing iptables rules :

"iptables -t nat -A PREROUTING -i eth0 -s eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128"

Now after several times , I need to remove this
rules without using "IPTABLES -F" .

How can I do it ?

You run the same command, but substitute -D for -A. You can also delete it by rule number. Check out iptables man page for more info.
