Subject: Re: How to drop an idle connection with iptables?

Hi Lloyd Standish:
     Thanks for your feedback greatly.
     I felt the scenario you described is not really what I want to know.

     I want to know if there is any way to set up iptables so
     that it will drop a connection after that connection has been idle 
for a specified period of time?

    I have tried connection tracking function of iptables, however it 
seems not work for my case.
    I wonder whether there are some other means to achieve this.
    Thanks.

    Best Regards.

+ I think you are referring to what is called "dead gateway detection."  
There are patches for current kernels to allow netfilter to do this 
(http://www.ssi.bg/~ja/#routes).
