Your opposite side should call your WAN IP , which is displayed on the “Status” page. 
4)   How to enable DMZ Host: Log in to the Router, click the “ Forwarding” menu on the left 
of your browser, and click  DMZ submenu. On the  DMZ page, click Enable radio 
button and type your IP address into the “DMZ Host IP Address” field, using 
192.168.1.169 as an example,  remember to click the Save button.

4.  I want to build a WEB Server on the LAN, what should I do?  1)  Because the WEB Server port 80 will inte rfere with the WEB management port 80 on the 
Router, you must change the WEB management  port number to avoid interference. 
2)   To change the WEB management port number : Log in to the Router, click the “Security” 
menu on the left of your browser, and click  Remote Management submenu. On the 
 Remote Management  page, type a port number except  80, such as 88, into the Web 
Management Port field. Click  Save and reboot the Router.

3)   Log in to the Router, click the “ Forwarding” menu on the left of your browser, and click 
the  Virtual Servers  submenu. On the  Virtual Servers page, click Add New…, then 
on the “ Add or Modify a Virtual Server ” page, enter “80” into the blank next to the 
“ Service Port”, and your IP address next to the “ IP Address”, assuming 192.168.1.188

5.  The wireless stations cannot connect to the Router.  1)  Make sure the  Enable Wireless Router Radio  is checked. 
2)   Make sure that the wireless stations SSID accord with the Routers SSID. 
3)   Make sure the wireless stations have right KEY for encryption when the Router is 
encrypted. 
4)   If the wireless connection is ready, but you can’t access the Router, check the IP Address 
of your wireless stations.

)  Note:  
For Windows 98 OS or before, the PC and Router may need to be restarted.   
¾  Setting IP address manually
 
1 Select  Use the following IP address  radio button. And the following items available 
2  If the Routers LAN IP addr ess is 192.168.1.1, specify the IP address as 192.168.1.x (x is 
from 2 to 254), and the  Subnet mask as 255.255.255.0. 
3  Type the Router’s LAN IP address (t he default IP is 192.168.1.1) into the Default gateway 
field. 
4 Select  Use the following DNS server addresses .  In the Preferred  DNS Server  field you 
can enter the same value as the  Default gateway or type the local DNS server IP address.

Appendix D: Glossary 
¾ 802.11b -  The 802.11b standard specifies a wire less networking at 11 Mbps using 
direct-sequence spread-s pectrum (DSSS) technology and oper ating in the unlicensed radio 
spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to 
as Wi-Fi networks. 
¾  802.11g -  specification for wireless networki ng at 54 Mbps using direct-sequence 
spread-spectrum (DSSS) technology, usi ng OFDM modulation and operating in the 
unlicensed radio spectrum at 2.4GHz, and backward compatibilit y with IEEE 802.11b devices, 
and WEP encryption for security. 
¾  DDNS  (D ynamic  Domain  Name  System)  - The capability of assigning a fixed host and domain 
name to a dynamic Internet IP Address.   
¾  DHCP  (D ynamic  Host  Configuration  Protocol)  - A protocol that autom atically configure the 
TCP/IP parameters for the all the PC(s) that are connected to a DHCP server. 
¾  DMZ  (D em ilitarized  Zone) - A Demilitarized Zone allows one local host to be exposed to the 
Internet for a special-purpose service such  as Internet gaming or videoconferencing. 
¾ DNS  (D omain  Name  System)  – An Internet Service that transla tes the names of websites into 
IP addresses. 
¾  Domain Name -  A descriptive name for an address or group of addresses on the Internet.   
¾ DSL  (D igital  Subscriber  Line) - A technology that allows data  to be sent or received over 
existing traditional phone lines. 
¾  ISP ( Internet  Service  Provider)  - A company that provides access to the Internet. 
¾  MTU  (Maximum Transmission Unit ) - The size in bytes of the largest packet that can be 
transmitted. 
¾  NAT  (N etwork  Address Translation)  - NAT technology translates IP  addresses of a local area 
network to a different IP address for the Internet. 
¾  PPPoE  (P oint to  Point  Protocol  over Ethernet)  - PPPoE is a protocol for connecting remote 
hosts to the Internet over  an always-on connection by simulating a dial-up connection. 
¾ SSID -  A Service  Set  Identification is a thirty-two char acter (maximum) alphanumeric key 
identifying a wireless local area network. Fo r the wireless devices in a network to 
communicate with each other, all devices must be configured with the same SSID. This is 
typically the configuration parameter for a wi reless PC card. It corresponds to the ESSID in 
the wireless Access Point and to the wireless network name.

¾ WEP  (W ired  Equivalent  Privacy)  - A data privacy mechanism bas ed on a 64-bit or 128-bit or 
152-bit shared key algorithm, as des cribed in the IEEE 802.11 standard.   
¾ Wi-Fi -  A trade name for the 802.11b wireless network ing standard, given by the Wireless 
Ethernet Compatibility Al liance (WECA, see http://www.wi-f i.net), an industry standards group 
promoting interoperabilit y among 802.11b devices. 
¾ WLAN  (W ireless  Local Area  Network)  - A group of computers and associated devices 
communicate with each other wirelessly, which  network serving users are limited in a local 
area.
