NAT Setup
NAT Loopback
Allows you to access the WAN IP address from inside your home or office network.
Virtual Server
The NAT firewall filters out unrecognized packets to protect your Intranet, so all hosts behind this device are
invisible to the outside world. If you wish, you can make some of them accessible by enabling the Virtual Server
Mapping. A virtual server is defined as a Service Port, and all requests to this port will be redirected to the
computer specified by the Server IP. Virtual Server can work with Scheduling Rules, and give user more flexibility
on Access control. For the details, please refer to Scheduling Rule.
Virtual Computers
Virtual Computer enables you to use the original NAT feature, and allows you to setup the one-to-one mapping of
multiple global IP address and local IP address.
Global IP: Enter the global IP address assigned by your ISP.
Local IP: Enter the local IP address of your LAN PC corresponding to the global IP address.
Enable: Check this item to enable the Virtual Computer feature.
Special AP
Some applications require multiple connections, like Internet games, Video conferencing, Internet telephony, etc.
Because of the firewall function, these applications cannot work with a pure NAT router. The Special Applications
feature allows some of these applications to work with this product. If the mechanism of Special Applications fails
to make an application work, try setting your computer as the DMZ host instead.
This device provides some predefined settings. Select your application and click “Copy to” to add the predefined
setting to your list.
Trigger: The outbound port number issued by the application.
Incoming Ports: When the trigger packet is detected, the inbound packets sent to the specified port
numbers are allowed to pass through the firewall.
Enable: Check this item to enable the Special AP feature.
