3.4.3. NAT Server
3.4.3.1. Basic
Fig. 54. Basic NAT server settings.
When the gateway is in Gateway with a Static-IP DSL/Cable Connection mode, the NAT server
functionality can be enabled or disabled.
You can restrict the maximum number of user traffic sessions by specifying the Max number of ses-
sions per user setting. In this way, you can prevent a single user from consuming too many network
resources by initiating a large number of network sessions.
A DMZ ( DeMilitarized Zone ) host receives all unrecognized TCP/IP packets from the NAT server on
the gateway; therefore TCP/IP networking applications running on the DMZ host would have better
compatibility with NAT.
To specify the DMZ host :
Enter the private IP address of the computer to be used as a DMZ host, and select the corre-
sponding check box.
3.4.3.2. Static NAT Mappings
Fig. 55. Static NAT mappings.
An ISP may provide more than one public IP address to its customer. A customer could use each of
the public IP addresses for one type of server to be accessed from the Internet. This requirement can
be satisfied by
Static NAT Mappings . This functionality can be enabled only when the gateway is in
Gateway with a Static-IP DSL/Cable Connection mode.
For example, say an ISP provides 5 public IP addresses, 61.16.33.114 to 61.16.33.118 inclusive, to its
customer, ABC Technology. The network administrator of ABC Technology decides to use
61.16.33.114 for the multi-WAN wired broadband switch gateway, 61.16.33.115 for their public Web
