I'm working on the Disaster Recovery (DR) network. Here is the requirement:
- The DR and Production network have same IP address; it is to simplified server configuration when disaster occurs.
- All remote is link via VPN IPSec tunnel through the Internet using PIX device at both end
- How are we going to do when remotes want access to both DR and Product networks? (Take note, Production network cannot be down)
- At the DR we are using Cisco router with FireWall+VPN IOS and all remotes use PIX.
Is it alright to create another tunnel at the remote side with the same destination IP address, if not how am I do it?
How should the routing go about? PIX is not intelligent to do complicated routing at the remote end.
I have also attached a diagram to help you to understand what the setup is like.
Thanks a lot.
