 CENTRIA WNDR4700/WNDR4720
Wireless AP
The CENTRIA can be configured as a wireless 
AP. This mode lets you add a second router to 
your network. To use the wireless AP feature, you need two routers: one set up as a router 
and the other set up as a wireless AP. 
For example, you could install the first router  in a ro
 om like a home office that has your 
Internet connection. Then, set up the second router as a wireless AP. Place the router that is 
an AP in a different room that has...

Wireless Repeating Function (WDS)
You can set the CENTRIA up to be used as a wire
less access point (AP). Doing this enables 
the router to act as a wireless repeater. A wireless repeater connects to another wireless 
router as a client where the network to which it connects becomes the ISP service.
Wireless repeating is a type of Wireless Distri butio
 n System (WDS). A WDS allows a wireless 
network to be expanded through multiple access points instead of...

The router is always in dual-band concurrent mode, unless you turn off one radio. If you 
enable the wireless repeater in either radio band, the wireless base station or wireless 
repeater cannot be enabled in the other radio band. However, if you enable the wireless base 
station in either radio band and use the other radio band as a wireless router or wireless base 
station, dual-band concurrent mode is not affected.

information and then modifies the source information in the request message, performing 
Network Address Translation (NAT):
•     The source address is replaced with your router’s public IP address. This is necessary 
because your computer uses a private IP address that is not globally unique and cannot 
be used on the Internet.

An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at 
destination port 6667. The IRC server not only responds to your originating source port, but 
also sends an “identify” message to your computer on port 113. Using port triggering, you can 
tell the router, “When you initiate a session with destination port 6667, you have to also allow 
incoming traffic on port 113 to reach the originating computer.” Using steps similar to...

Internet to initiate a connection to a server computer on your network. Normally, your router 
ignores any inbound traffic that is not a response to your own outbound traffic. You can 
configure exceptions to this default rule by using the port forwarding feature. 
A typical application of port forwarding can be shown by reversing the client-server 
relationship from the previous web server example. In this case, a remote computer’s 
browser needs to...

Port triggering does not require that you know the computer’s IP address in advance. The 
IP address is captured automatically.

rt forwarding requires that you specify the  computer’s IP address during configuration, 
and the IP address can never change.
