Port Triggering
Some Internet applications or games use alternate ports to communicate between server and LAN host. When
you want to use those applications, enter the triggering (outgoing) port and alternate incoming port in this table.
The Router will forward the incoming packets to the LAN host.
1. Enter the application name, range of port numbers, and the incoming port range.
2. You can click the Add to List button to add Port Triggering or Delete selected application.
Click the Save Settings button to save the settings, click the Cancel Changes button to undo your changes, click
the Show Tables to see the details.
Setup Tab - UPnP Page
UPnP forwarding can be used to set up public services on your network. Windows XP can modify those entries via
UPnP when UPnP function is enabled by selecting Yes. See Figure 6-15.
1. Select the Service from the pull-down menu.
2. If the Service you need is not listed in menu, please click the Service Management button to add the new
Service Name, and enter the Protocol and Port Range. Click the Add to List button. Then, click the Save
Setting button. Click the Exit button.
3. Enter the Name or IP Address of the server that you want the Internet users to access. Then enable the entry.
Click the Add to List button, and configure as many entries as you would like. You also can Delete selected
application.
Setup Tab - One-to-One NAT
One-to-One NAT creates a relationship which maps valid external addresses to internal addresses hidden by NAT.
Machines with an internal address may be accessed at the corresponding external valid IP address. See Figure
6-16.
Creating this relationship between internal and external addresses is done by defining internal and external
address ranges of equal length. Once that relationship is defined, the machine with the first internal address is
accessible at the first IP address in the external address range, and the second machine at the second external IP
address, and so on.
