I am trying to create an exact replica of the production network at the DR location. Using replication from host to host, host to vmdk, and back up data, I am replicating the servers and data over. Now I need the same subnet mirrorred along with the server names and domain. Currently the production network and DR site use different subnet addresses separated by a point to point T3 connection.
Main reasons:
Considered L2TPv3, but this doesn't solve my problem of mirroring the systems. I can't bring up 2 mirrored domain controllers or any replicated servers up at the same time.
Thinking of using a router to NAT from DR subnet to the mirrorred production subnet. Adds a lot of complexity and IP mapping conplexity.
Also considering setting up a DMZ on the DR PIX with the production subnet. Allows me to route traffic to the DR subnet and to the Internet. Allows me to filter traffic to avoid name and IP conflicts.
Of course any testing that will be done will require disabling the T3 connection and accessing the DR network from another path such as VPN.
Looking for thoughts, recommendations, previous configurations.
Thanks in advance.

Hi,
This is a typical cold DR site setup which normally only used in Disaster time only. The only two option available ti test DR site system are as below.
Disable the communication from main site
Enforce the NAT & ACl at DR to main site link router.
Option two will allow the DR system access and application validation from main site.
Thanks
