Setup > One-to-One NAT
One-to-One NAT (Network Address Translation) creates
a relationship that maps valid external IP addresses to
internal IP addresses hidden by NAT. A device with an
internal IP address may be accessed at the corresponding
external valid IP address.
To create this relationship, define internal and external
IP address ranges of equal length. Once the relationship
is defined, the device with the first internal IP address is
accessible at the first IP address in the external IP address
range, and so forth.
For example, you have a Local Area Network (LAN) for which
the ISP has assigned the IP address range of 209.19.28.16
to 209.19.28.31, with 209.19.28.16 used as the Wide Area
Network (WAN) or NAT public IP address of the Router.
The address range of 192.168.168.1 to 192.168.168.255 is
used for the devices on the LAN. With One-to-One NAT,
the devices with the internal IP addresses of 192.168.168.2
to 192.168.168.15 may be accessed at the corresponding
external IP addresses.
NOTE: The Router’s WAN IP address should not
be included in the range you specify.
