VPN Tunnel Same Subnet....what to do?
Posted on 2006-05-31
We are going establish a VPN tunnel between one of our Remote_A office and another External_Data_Center. The problem is that we both have the same subnets. Also, add in the fact that Remote_A is already established site-to-site VPN with Remote_B, Remote_A and Remote_B, are part of the same Domain and Company. External_Data_Center, is an external entitiy.
Current IP range:
Remote_A = 192.168.1.0/24
Remote_B = 192.168.100.0/24
External_Data_Center = 192.168.1.0/24
Remote_A and Remote_B are connected via Cisco PIX VPN
This is the extent of my knowledge on this situation, the problem is, that I am the Admin in the US, and this is the second hand information I am receiving from the Admin in Turkey....let me know if you need anything else
Essentially, my quesitons are...
1. Can I establish VPN connectivity with someone of the same Subnet and still distinguish the traffic?
2. If we have to change the IP range at the Remote_A location, what can we change it to that would still allow Remote_A and Remote_B to communicate?
