Using Reserved IP Addresses for Private IP
Addressing
The OnBoard administrator should assign a private IP address to each
connected device from one of the three IP Internet address ranges that are
reserved for use on internal networks.
Any user who needs native IP access to the
OnBoard needs to create a named VPN
connection profile, then to create a VPN
tunnel to the OnBoard before enabling
native IP. The requirements for creating the
VPN tunnel and the IP addresses to use vary
depending on whether IPSec or PPTP is
being used.
