Application Example: Port Triggering for Internet Relay Chat 
Some application servers, such as FTP and IRC servers, send replies to m\
ultiple port 
numbers. Using port triggering, you can tell the router to open more inc\
oming ports when a 
particular outgoing port starts 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 must a\
lso allow 
incoming traffic on port 113 to reach the originating computer.” The following sequence shows 
the effects of the port triggering rule you have defined:
1.  Y
ou open an IRC client program to start a chat session on your computer. 
2. Y
our IRC client composes a request message to an IRC server using a desti\
nation port 
number of 6667, the standard port number for an IRC server process. Your computer then 
sends this request message to your router.
3.  Y
our router creates an entry in its internal session table describing thi\
s 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.  
						

							Specify Internet Port Settings 
143  AC750 Wireless Dual Band Gigabit Router R6050
4. Noting your port triggering rule and observing the destination port number of 6667, your 
router creates another 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 
(for example, port 33333) as the destination port and sends an “identify” message to your 
router with destination port 113.
6. When your router receives the incoming message to destination port 33333, it checks its 
session table to see if a session is active for port number 33333. Finding an active session, 
the router restores the original address information replaced by NAT and sends this reply 
message to your computer.
7. When your router receives the incoming message to destination port 113, it checks its 
session table and finds an active session for port 113 associated with your computer. The 
router replaces the message’s destination IP address with your computer’s IP address and 
forwards the message to your computer.
8. When you finish your chat session, your router eventually senses a period of inactivity in the 
communications. The router then removes the session information from its session table, 
and incoming traffic is no longer accepted on port numbers 33333 or 113.

Note:The Setup Wizard can detect your Internet connection during 
installation, but if the router cannot get a WAN IP address, the Setup 
Wizard cannot automatically resolve this issue.
If you are attempting to set up your NETGEAR router as a replacement for an ADSL gateway 
in your network, the router cannot perform many gateway services. For example, the router 
cannot convert ADSL or cable data into Ethernet networking information. NETGEAR does 
not support such a configuration.
To check the WAN IP address: 
1. Launch a web browser from a computer or wireless device that is connected to the 
network.
2. Enter http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
3. Enter the router user name and password.
The user name is admin. The default password is password. The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4. Click the ADVANCED tab.
The Router Status screen displays.
5. In the Internet Port pane, check that an IP address is shown for the Internet port.
If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.
For more information about the Internet connection, see View the Internet Connection 
Status on page 81.
6. If your router cannot obtain an IP address from the ISP, try to force your cable or DSL 
broadband modem to recognize your new router by restarting your network in this order: 
a.Unplug and turn off the cable or DSL broadband modem. 
b. Unplug the router.
c. Plug in the cable or DSL broadband modem and turn it on. 
d. Wait two minutes.
e. Plug in the router and wait two minutes.
If your router is still unable to obtain an IP address from the ISP, the problem might be one of 
the following:
•Your Internet service provider (ISP) might require a login program.
Ask your ISP if it requires PPP over Ethernet (PPPoE) or some other type of login. If your 
ISP requires a login, the login name and password might be set incorrectly.
