Dear Mr Krishna,
Always a good idea to remove passwords (even encrypted ones) and
production IP address's from configuration's posted to public mailing

Dear Mr.Amol,
Thanks for your reply. I tried to allow the traffing from out side to
inside
but still it failed. I think iam doing a small mistake in diverting the
traffic from out side to inside/internal.
