Global Topology

IPsecGW connects multiple network segments and routes traffic between its interfaces. It is then a routing device and can operate in 2 network routing scenarios:

• Connected Network : Routing traffic between directly connected networks. The figure shows where 192.168.201.1 wants to reach 192.168.102.1. This scenario is used in small networks where there is a limited and controlled number of subnets.

• Routed Network : Routing traffic from directly connected network via a router to reach a remote network. The figure shows where 48.0.0.1 wants to reach 192.168.102.1. This scenario is used by large network operators where IPsecGW acts as a security border router inter-connecting multiple partner networks.
