Hi Phil,

Thanks for the reply. I just had idea that a cache is maintained by NAT but I
did not know the exact location/details. I have seen that the entry for which
DNAT was applied still present in "/proc/net/nf_conntrack". 

Can you please provide any information on when this entry gets expired? Is this
timeout configurable?

Thanks,
Dath Raj
