Address Configuration for Connected Devices
Example 2: Two Private Subnets and VPN
Configuration
Figure A-6 shows an example with four devices. Two subnets must be created
because the devices “sp3” and “sp4” have IP addresses that cannot be
changed, and their addresses are not in the same network range as the other
two devices. Configuration details follow, including how to set up VPN
connections.
