My issue is like this:
From our network, we have to connect to different client networks and their internal LAN is not defined by us. Every client is connected through separate IPSEC GRE tunnel on CISCO devices. now consider below scenario:
Client A having an internal IP address scheme of 192.168.1.0/24 and Client B also having the same. I have to route the packets from our Linux server --> our internal F/W --> our Router --> Respective Tunnels. (Suppose, both Clients having machines with same IP address 192.168.1.100)
Now, How can I route the packets from my internal LAN to respective clients? is there any changes I have to make in My network?
(Hope the question is clear to you, I'm not a hard core network engineer :))
