Answer:
network-to-network
Step-by-step 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.
