Gigabit Content Security Router User’s Manual
10.4 One to One NAT
As both the device and ATU-R need only one actual IP, if ISP issued more than one actual IP (such as eight
ADSL static IP addresses or more), users can map the remaining real IP addresses to the intranet PC virtual
IP addresses. These PCs use private IP addresses in the Intranet, but after having One to One NAT mapping,
these PCs will have their own public IP addresses.
For example
, if there are more than 2 web servers requiring public IP addresses, administrators can map
several public IP addresses directly to internal private IP addresses.
Example
:Users have five available IP addresses - 210.11.1.1~5, one of which, 210.11.1.1, has been
configured as a real IP for WAN, and is used in NAT. Users can respectively configure the other four real IP
addresses for Multi-DMZ, as follows:
210.11.1.2
192.168.1.3
210.11.1.3
192.168.1.4
210.11.1.4
192.168.1.5
210.11.1.5
192.168.1.6
"
Attention
The device WAN IP address can not be contained in the One-to-One NAT IP configuration.
