Set Up the Router in Bridge Mode
The R6300 WiFi Router can be configured in bridge mode. This mode lets you connect 
multiple devices wirelessly at the faster 802.11ac speed. To use the router in Bridge mode, 
you need two R6300 WiFi Routers; one set up as a router and the other se\
t up as a bridge. 
Figure 8. Router in Bridge mode with an 802.11ac WiFi connection
Installing a R6300 router as a bridge offers the following benefits:
•      Y
ou can take advantage of Gigabit WiFi speeds on current devices
•     Use Gigabit WiFi for applications like video and gaming.
•     Connect multiple devices like NAS, Smart 
 TV, NeoTV, Blu-ray Player, game console at 
Gigabit WiFi speeds using a WiFi link
•      A
void the need for separate WiFi adapters for each device.
For example, you could install the first R6300 WiFi Router in a room lik\
e a home office that 
has your Internet connection. 

After this router is up and running, set up the second router in 
Bridge mode. Then place the router in Bridge mode in a different room that has your home 
entertainment center. Cable the router in Bridge mode to your Smart TV, DVR, game console 
or Blu-ray player, and then use its 802.11ac WiFi connection to the first R6300 router. 
To set up the R6300 WiFi Router in Bridge mode:
1.  Make sure that the first router (the one cabled to the modem) has an I\
nternet connection 
and that wireless devices can connect to it. Make a note of the followin\
g items: SSID, 
security mode, wireless password, operating frequency (either 2.4 GHz o\
r 5 GHz).

Wireless Repeating Function (WDS)
You can set the R6300 WiFi Router up to be used as a wireless access poin\
t (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 becom\
es the ISP service.
Wireless repeating is a type of Wireless Distribution System (WDS). A WDS allows a wireless 
network to be expanded through multiple access points instead of using a\
 wired backbone to 
link them. 

The following figure shows a wireless repeating scenario.

Note:   If you use the wireless repeating function, you need to select either 
WEP or None as a security option in the Wireless Settings screen. 
The WEP option displays only if you select the wireless mode  Up to 
54 Mbps in the Wireless Settings screen.
Wireless Base Station . 
 The router acts as the parent access point, bridging traffic to and 
from the child repeater access point. The base station also handles wireless and wired local 
computers. To configure this mode, you have to know the MAC addresses of the child 
repeater access point.
Wireless Repeater . 
 The router sends all traffic from its local wireless or wired computers to a 
remote access point. To configure this mode, you have to know the MAC address of the 
remote parent access point.  
						

							Advanced Settings86
R6300 WiFi Router 802.11ac Dual Band Gigabit 
The R6300 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.
For you to set up a wireless network with WDS, both access points have t\
o meet the following 
conditions:
•     Both access points have to use the same SSID, wireless channel, and encr\
yption mode.
•     Both access points have to be on the same LAN IP subnet. 
 That is, all the access point 
LAN IP addresses are in the same network.
•      All LAN devices (wired and wireless computers) are configured to opera\
te in the same 
LAN network address range as the access points.

as the repeater, you might need to change additional configuration 
settings. In particular, you should disable the DHCP server function 
on the wireless repeater AP.
To configure the router as a repeater unit:
1. Log in to the router that will be the repeater. Select Basic > Wireless Settings and 
verify that the wireless settings match the base unit exactly. The wireless security option 
has to be set to WEP or None.
2. Select Advanced > Wireless Repeating Function, and select the Enable Wireless 
Repeating Function check box and the Wireless Repeater radio button.
3. Fill in the Repeater IP Address field. This IP address has to be in the same subnet as the 
base station, but different from the LAN IP address of the base station.
4. Click Apply to save your changes.
5. Verify connectivity across the LANs. 
A computer on any wireless or wired LAN segment of the router should be able to 
connect to the Internet or share files and printers with any other wireless or wired 
computer or server connected to the other access point.
Port Forwarding and Triggering
By default, the router blocks inbound traffic from the Internet to your computers except replies 
to your outbound traffic. You might need to create exceptions to this rule for these purposes:
•     To allow remote computers on the Internet to access a server on your local network. 
•     To allow certain applications and games to work correctly when your router does not 
recognize their replies.
Your router provides two features for creating these exceptions: port forwarding and port 
triggering. The next sections provide background information to help you understand how 
port forwarding and port triggering work, and the differences between the two.

Remote Computer Access Basics
When a computer on your network needs to access a computer on the Internet, your 
computer sends your router a message containing the source and destination address and 
process information. Before forwarding your message to the remote computer, your router 
has to modify the source information and create and track the communication session so that 
replies can be routed back to your computer. 
Here is an example of normal outbound traffic and the resulting inbound responses:
1. You open a browser, and your operating system assigns port number 5678 to this 
browser session. 
2. You type http://www.example.com into the URL field, and your computer creates a web page 
request message with the following address and port information. The request message is 
sent to your router.
Source address. Your computer’s IP address.
Source port number. 5678, which is the browser session. 
Destination address. The IP address of www.example.com, which your computer finds 
by asking a DNS server.
Destination port number. 80, which is the standard port number for a web server 
process.
3. Your router creates an entry in its internal session table describing this communication 
session between your computer and the web server at www.example.com. Before sending 
the web page request message to www.example.com, your router stores the original 
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.
•     The source port number is changed to a number chosen by the router, such as 
33333. This is necessary because two computers could independently be using the 
same session number.
Your router then sends this request message through the Internet to the web server at 
www.example.com.
4. The web server at www.example.com composes a return message with the requested web 
page data. The return message contains the following address and port information. The 
web server then sends this reply message to your router.
Source address. The IP address of www.example.com.
Source port number. 80, which is the standard port number for a web server process.
Destination address. The public IP address of your router.
Destination port number. 33333.
5. Upon receiving the incoming message, your router checks its session table to determine 
whether there is an active session for port number 33333. Finding an active session, the  
						

							Advanced Settings
90 R6300 WiFi Router 802.11ac Dual Band Gigabit 
router then modifies the message to restore the original address information replaced by 
NAT. Your router sends this reply message to your computer, which displays the web 
page from www.example.com. The message now contains the following address and port 
information.
Source address. The IP address of www.example.com.
Source port number. 80, which is the standard port number for a web server process.
Destination address. Your computer’s IP address.
Destination port number. 5678, which is the browser session that made the initial 
request.
6. When you finish your browser session, your router eventually detects a period of inactivity in 
the communications. Your router then removes the session information from its session 
table, and incoming traffic is no longer accepted on port number 33333.
Port Triggering to Open Incoming Ports
In the preceding example, requests are sent to a remote computer by your router from a 
particular service port number. Replies from the remote computer to your router are directed 
to that port number. If the remote server sends a reply to a different port number, your router 
does not recognize it and discards it. However, some application servers (such as FTP and 
IRC servers) send replies to multiple port numbers. Using the port triggering function of your 
router, you can tell the router to open additional incoming ports when a particular outgoing 
port originates a session.
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 the 
preceding example, the following sequence shows the effects of the port triggering rule you 
have defined:
1. You open an IRC client program to start a chat session on your computer. 
2. Your IRC client composes a request message to an IRC server using a destination port 
number of 6667, the standard port number for an IRC server process. Your computer then 
sends this request message to your router.
3. Your router creates an entry in its internal session table describing this communication 
session between your computer and the IRC server. Your router stores the original 
information, performs Network Address Translation (NAT) on the source address and port, 
and sends this request message through the Internet to the IRC server. 
4. Noting your port triggering rule and having observed the destination port number of 6667, 
your router creates an additional session entry to send any incoming port 113 traffic to your 
computer.
5. The IRC server sends a return message to your router using the NAT-assigned source port 
(as in the previous example, say port 33333) as the destination port. The IRC server also 
sends an “identify” message to your router with destination port 113.
