Idle timeout in IPSEC using racoon
 

I have Successfully Established Tunnel between two site and all other parameters are working as expected.

Now i want that if no traffic is seen between two sites for some specific interval then tunnel should be disconnected.

I have searched and tried all parameter as specified in
racoon.conf but none is working as expected.
If any one has any idea regarding implementation of idle timeout in ipsec using racoon, please post here.

Thanking You,
Tushar
