Appendix A: Advanced Device Configuration 373
Address Configuration for Connected Devices
Private subnet(s) should use IP addresses
from one of the three IP address ranges
reserved for use on internal networks.
• “Using Reserved IP Addresses for Private
IP Addressing” on page 374
Even if virtual IP addresses are used (as
described below), the planned real IP
address for each device must be either
configured manually as a static IP address
or configured as a fixed address in the
OnBoard’s DHCP server dhcp.conf
configuration file.
• “Options for Assigning IP Addresses to
Connected Devices” on page 404
A virtual network may be created in the
following cases:
• To hide a device’s private IP addresses
from non-administrative users who are
not configured for native IP access.
• When it is desired that multiple non-
contiguous private subnets be supported
by a single network route (or, in the case
of IPSec, a single tunnel) on the client for
VPN or Native IP access. This would be
the case when connected devices are
already configured using IP addresses
from multiple address ranges and it is not
feasible to change previously-defined
device IP addresses.

Addresses?” on page 393

Ranges
