We have a number of site to site VPN tunnels which each have a their own consecutive subnet, for example:
Branch 1 - 192.168.1.0/24 Branch 2 - 192.168.2.0/24 Branch 3 - 192.168.3.0/24 Branch 4 - 192.168.4.0/24 Branch 5 - 192.168.5.0/24 Branch 6 - 192.168.6.0/24
We also have a number of users whom need to create PPTP tunnels while they are roaming. Occasionally those roaming users hit the expected problem that their local network matches that of Branch 1.
Note: All VPN tunnels terminate at Branch 1 and are given an IP in the
The network design is the result of a legacy management system of which the network was a product of. I am now working towards adding additional subnets to Branch 1 to terminate the VPN tunnels. So, for example, Branch 1 would have the following subnets:
192.168.1.0/24 10.0.1.0/24 10.0.2.0/24 10.0.3.0/24
What I am trying to get my head around is where the conflict is causing problems. Essentially, the question is; if the VPN tunnels terminate to a subnet that does not match that of the roaming users' local network - will the conflict remain due to the
192.168.1.0/24 subnet existing on the terminating device, even though it's not the actual subnet the roaming client is connecting on?
