If IPsec is required to protect traffic from hosts behind the IPsec peers, tunnel mode must be used. This means that the original IP packet will be encapsulated in a new IP packet and encrypted before it is sent out of the network. See Cisco's reference implementation of DMVPN (mGRE, IPSec in Transport Mode, NHRP, OSPF) for a concrete example and explanation. The original header can be "obfuscated" by putting the entire IPsec datagram in an additional GRE tunnel tunnel, assuming that the device performing the GRE tunneling is different from the IPsec endpoints. The traffic from Site A (Juniper) will source NAT it’s local traffic through the VPN to meet the encryption domain defined at Site B (Cisco). This is a Cisco ASA 5515-X with software 9. IPsec AH transport mode. Here is a image taken from Cisco’s website to show the difference.
