Hi,

That looks correct as per pages 23-24 of the following link

http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/admin_guide/Cisco-Expressway-Administrator-Guide-X8-2.pdf

LAN 1 and LAN2 interfaces must be on different, non overlapping subnets.

Thank you for your reply, but I have a question regarding the communication between Expressway-C and E. While C in different network how E will communicate with C and no default GW?

Essentially this is achieved by adding static routes to the E server to point all internal networks to the "Transit DMZ" (internal DMZ), and then everything else goes to the "Services DMZ".
