Planet Technology ADSL 2/2+ Router with USB Port ADE-3410v2 - Manual (Page 39)

Service Name: Select one service item, such as Mail (SMTP), Mail (POP3), Web Server
(HTTP), FTP Server, and TFTP, from the list. The information about the selected item
will appear in the box below.
Customized server: Enter a new service name to establish a specified user service
category.
Server IP address: When you intend to assign a specified address to the virtual server,
enter the server IP address here.
External port start/end: When you have already selected one service, the port number
will appear automatically. You can change it as you need.
Protocol: Choose proper protocols for your services.
Internal port start/end: When you have already selected one service, the port number
will appear automatically. You can change it as you need.
PC1 (192.168.1.10): WEB Server
Note: The default port number of the external port and the internal port is 80. In this
example, it is changed to 8060.
After proper modifications, click “Save/Apply”. (This configuration will take effective at
once.)
PC2 (192.168.1.20): FTP server
After proper modifications, click “Apply” (This configuration will take effective at once).
If you want to delete a certain virtual server, you can choose this virtual server and click
“Remove” to delete it.
After the virtual server is already configured, any user from the Internet can access to
your virtual server. They must use the Internet IP address (the IP address provided by
your ISP), for example:
Http://203.70.212.52:8060 and Ftp://203.70.212.52
The access will be led to the local server which possesses an private IP address, that is,
according to the service categories (TCP/UDP port numbers), the ROUTER will lead the
external service requests to an appropriate server (located at another internal IP address).
Suggestion: Use a fixed WAN IP address. In this way, it is more convenient than an
dynamic IP address.
3.5.3.2 NAT -- Port Triggering Setup
Click “Port Triggering” to pop up an interface as below. In this interface, you can
configure Port Triggering.
Some applications require that specific ports in the Router's firewall be opened for access
by the remote parties. Port Trigger dynamically opens up the 'Open Ports' in the firewall
when an application on the LAN initiates a TCP/UDP connection to a remote party using
the 'Triggering Ports'. The Router allows the remote party from the WAN side to
establish new connections back to the application on the LAN side using the 'Open Ports'.
