Subject: prohibiting iptables to insert a rule twice

Hi,
I am working on a patch for iptables.c to prohibit inserting the same 
rule twice. Inserting same rule twice does not cause any problems but 
also is not meaningful.

After the patch iptables will has an option to force the system to 
insert the rule twice but by default it will check whether the rule is 
already inserted or not and will give warning.

I think that checking the rule in the system may take too much time for 
systems with thousands of rules, so an option argument will be a good 
choice.

I wonder why this has not been done before. Please write your 
suggestions and thoughts.

thanks,
