You have configured a VPN between your gateway router and another gateway router of the partner organization. You need to ensure that the communication between both the router is encrypted using IPSec. Which type of IPSec configuration are you doing

network-to-network

Explanation:

A network-to-network connection requires the setup of IPsec routers on each side of the connecting networks to transparently process and route information from one node on a LAN to a node on a remote LAN.

The information needed for a network-to-network connection include:

• The externally-accessible IP addresses of the dedicated IPsec routers.

• The network address ranges of the LAN/WAN served by the IPsec routers (such as 192.168.1.0/24 or 10.0.1.0/24).

• The IP addresses of the gateway devices that route the data from the network nodes to the Internet.
