! --------------------------------------------------------------------------------
! This example configuration shows what WE did to get Amazon VPC working with our
! ASAs.  We use version 8.3(1). This config has not been reviewed or otherwise
! blessed in any way by anyone at Amazon.  YMMV.
! 
! It differs from Amazon's supplied config by using two different sets of
! crypto maps and ACLs, so it brings both tunnels up simultaneously.
!
! For the purposes of the example, the physical datacenter network is 172.16.1.0/24
! and the VPC is 10.0.0.0/16.
