I need some help. I am having trouble wrapping my head around a firewall nat issue, in terms of how to accomplish a setup between my Production site and a DR Site. Both have the same internal subnet of 192.168.101.0/24. Here is my issue:
I have a server with an address of 192.168.101.222 at my DR Site. Nothing will ever use that address in either Production site or DR Site other than that server, this is the only difference between networks. I need the ability to do a VPN to that one server. For instance if a user in my production site needs to go to that 192.168.101.222 ip I need it to go across the VPN to my DR site and access that server.
I know I need to NAT that IP to another IP and I get the concept but when I start mapping it out I'm confusing myself or whatever. I need help on this logic. There is a Cisco ASA at both locations
