10.4 One-to-One NAT Mapping
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 IPs or more), users can map the remaining real IPs to
the intranet PC virtual IPs.
Application
If any application such as Network Game, which does not support virtual IP addresses,
is used, we recommend that users map the actual Internet IP directly to the virtual Intranet
IP. Follow the next example to input IP addresses:
Example
Users have five available IPs - 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 IPs 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.
