Email and FTP. A virtual server is defined as a service port, and all requests from Internet
to this service port will be redirected to the computer specified by the server IP. Any PC
that was configured as a virtual server must have a static or a reserved IP address
because its IP address may change when using the DHCP function.

Step 1: A local host makes an outgoing connection using a destination port number
defined in the Trigger Port field.
Step 2: The router records this connection, opens the incoming port or ports associated
with this entry in the Port Triggering table, and associates them with the local
host.
Step 3: When necessary, the external host will be able to connect to the local host using
one of the ports defined in the Incoming Ports field.
To add/modify a port triggering entry:
Step 1: Click Add New…/Modify shown in Figure 4-20, you will see a new screen
shown in Figure 4-21.
Step 2: Select the application you want from the “Common Applications”, then the

How do I configure the router to access Internet by ADSL users?
Step 1: First, configure the ADSL modem in RFC1483 bridge model.
Step 2: Connect the Ethernet cable from your ADSL modem to the WAN port on the
router. The telephone cord plugs into the Line port of the ADSL modem.
Step 3: Login to the router, click the menu Network→WAN on the left of your browser.
On the WAN screen, select “PPPoE” for the type of WAN connection. Then
enter the user name and password in the corresponding field, and finish it by
clicking Connect.
Figure B-1
Step 4: If your ADSL lease is in “pay-according-time” mode, select “Connect on
Demand” or “connect Manually” or “Time-based Connecting” for Internet
connection mode. Type an appropriate number for “Max Idle Time” or “Period of
Time” to avoid wasting paid time. Otherwise, you can select “Connect
Automatically” for Internet connection mode.

How do I configure the router to access Internet by Ethernet users?
Step 1: Login to the router, click the menu Network→WAN on the left of your browser,
On the WAN screen, select “Dynamic IP” for "WAN Connection Type", and
finish it by clicking Save.
Step 2: Some ISPs require that you register the MAC address of your adapter, which is
connected to your cable or DSL modem during installation. If your ISP requires
MAC register, login to the router and click the menu Network→MAC Clone. On
the MAC Clone screen, if your PC’s MAC address is a proper MAC address,
click the "Clone MAC Address" button and your PC’s MAC address will be filled
in the "WAN MAC Address" field; Or else, enter the specific MAC address into
the "WAN MAC Address" field manually. Then click the Save button. It will take
effect after rebooting.

I want to use Netmeeting, what do I need to do?
If you start Netmeeting as a sponsor, you don’t need to do anything with the router.
If you start as a responsor, you need configure Virtual Server or DMZ Host as follows:
Method one: Use Virtual Server
Login to the router, click the menu Forwarding→Virtual Servers. On the Virtual Server
screen, add a Virtual Server rule as shown in the next screen: configure 1720 as the
“Service Port” and enter your IP address (assuming 192.168.2.102 for an example), then

I want to build a WEB Server on the LAN, what should I do?
Because the WEB Server port 80 will interfere with the WEB management port 80 on the
router, you must change the WEB management port number to avoid interference. And
then add a WEB Server on your LAN. You can follow the steps below to proceed.
Step 1: To change the WEB management port number: Login to the router, click the

For remote access to the router, you should enter the address for example:
http://61.45.120.20:88 (presume the WAN IP address of the router is
61.45.120.20) to access the Router.
Step 2: To add a WEB Server: Login to the router, click the menu Forwarding→Virtual
Servers on the left of your browser, On the Virtual Server screen, add a Virtual
Server rule as shown in the next screen: configure “80” as the “Service Port”,
