I would appreciate at least a response. Yes is doable. No impossible! I posted a link in IPSEC as to what I am looking for. I was told that pfSense cannot do this. I was wondering if this is a feature that could be added. I posted $200. Honestly I don't know how much this feature would cost so if I am off, let me know what would be an appropriate price.

I am looking at implementing a solution to manage all of my customers servers and resources with an enterprise monitoring application. I need to create VPN tunnels to each remote site. My problem is that some of the sites have the same subnets and I cannot change them. I was wondering if there was a way to make a customers pfsense translate their subnet into a different subnet so that I can communicate with them. I have done this with a Cisco vpn-3000 concentrator and was hoping there was a solution for connecting multiple sites to one location where some of the remote sites might have identical subnets.
Ex. 1: Notice customer 1 and 3 have the same subnet.
Ex. 2: Customer 3 has translated their subnet into a different subnet so that there is not a conflict for Operations to communicate with both sites simultaneously.
Here is an example of how a Cisco VPN concentrator does this:
Notice how it translates the network
By the way...I did the diagram using Network Notepad which is free of charge at www.networknotepad.com
