considered to be a domain name, DNS datagram will be sent, at this time, no matter what the 
destination port is, the desti nation port in the sent datagram is  always 53. If not, it will be sent 
as a whole UDP datagram.   
¾  Detect Result -  The interval between sending datagram  and recving datagram, uint is ms.

Appendix B: FAQ 
1.  How do I configure the router to access Internet by ADSL users? 
Step 1: First, configure the ADSL m odem 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. 
 
Figure B-2 
)  Note: 
1)  Sometimes the connection can not be disc onnected although you specify a time to Max 
Idle Time, because some applications still visit the Internet continually  in the background. 
2)  If you are a Cable user, please confi gure the router following the above steps.

2.  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 addr ess will be filled in the WAN MAC Address 
field; Or else, enter the s pecific MAC address into the  WAN MAC Address field 
manually. Then click the  Save button. It will take ef fect after rebooting.

3.  I want to use Netmeeting, what do I need to do? 
1) If you start a Netmeeting as  a host, no configuration is needed  but entering the invitee’s IP 
address. 
2) If you start a Netmeeting as an invitee, you need  to configure Virtual Server or DMZ Host first. 
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 192.168.1.102 for an example), then click select the status 
Enabled  and click Save.

Figure B-4 
)  Note: 
Your opposite side should call your WAN IP, which is displayed on the “Status” page. 
Method two: Use DMZ Host 
Login to the router, click the menu  Forwarding→DMZ . On the DMZ screen, select “Enable”, and 
enter your IP address into the “DMZ Host IP  Address” field (using 192.168.1.102 as an example), 
then to click the  Save button.

7.  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 fo llow the steps below to proceed. 
Step 1:  To change the WEB management port number:  Login to the router, click the menu 
Security →Remote Management . On the Remote Management screen, enter a port 
number except 80 (such as 88) into the Web Management Port  field. Click Save and 
the router will reboot.
