BASIC NETWORK
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. 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 LAN Server IP. Virtual Server can work with Scheduling Rules and give user more flexibility on Access
control.
For details, refer to Scheduling Rule.
1.
Public Port: Select pre-defined or enter user-defined service port.
2.
Server IP: Enter the local server IP address of your LAN PC.
3.
Private Port: Enter service port. Commonly same as public port.
4.
Protocol: Select Both, TCP or UDP.
5.
Time Schedule: Select Always or pre-defined time schedule in Schedule Rule setting.
6.
Rule: Check to enable this 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.
1.
Global IP: Enter the assigned global IP address.
2.
Local IP: Enter the local IP address of your LAN PC corresponding to the global IP address.
3.
Enable: Check to enable this feature.
Special AP & ALG
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 this 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 add the predefined setting
to your list.
1.
Trigger: The application-issued outbound port number.
2.
Incoming Ports: When the trigger packet is detected, the inbound packets sent to the specified port
numbers are allowed to pass through the firewall.
3.
Time Schedule: Select Always or pre-defined time schedule in Schedule Rule setting.
28
Auto-configuration type: Select Stateless or Stateful (Dynamic IPv6).
Router Advertisement Lifetime: Each router periodically multicasts a Router Advertisement
from each of its interfaces, announcing the IP address(es) of that interface. Use this option to
set the period that the router broadcasts its router advertisements.
