Application Example: Port Triggering for Internet Relay Chat 
Some application servers, such as FTP and IRC servers, send replies to multiple port 
numbers. Using port triggering, you can tell the DST router to open more incoming 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 DST router, “When you initiate a session with destination port 6667, you must also 
allow incoming traffic on port 113 to reach the originating computer.” The following sequence 
shows the effects of this port triggering rule:
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 DST router.
3. Your DST router creates an entry in its internal session table describing this communication 
session between your computer and the IRC server. Your DST 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 observing the destination port number of 6667, your DST 
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 DST router using the NAT-assigned source 
port (for example, port 33333) as the destination port. The IRC server also sends an 
“identify” message to your DST router with destination port 113.
6. When your DST 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 DST router restores the original address information replaced by NAT and 
sends this reply message to your computer.
7. When your DST 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 
DST 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 DST router eventually senses a period of inactivity 
in the communications. The DST router then removes the session information from its 
session table, and incoming traffic is no longer accepted on port numbers 33333 or 113.

Quick Tips
This section describes tips for troubleshooting some common problems.
Sequence to Restart Your Network
When you must restart your network, follow this sequence:
1. T
urn off and unplug the modem. 
2. T
urn off the DST router.
3.  Plug in the modem and turn it on. W
 ait two minutes.
4.  T
urn on the  DST router and wait two minutes.
Check Ethernet Cable Connections
If your device does not power on, make sure that the Ethernet cables are\
 securely plugged 
in. 
The Internet LED on the DST router is lit if the Ethernet cable connecti\
ng the DST router and  the modem is plugged in securely and the modem and DST router are turned\
 on. 
If one or more powered-on computers are connected to the DST router by a\
n Ethernet cable, 
the corresponding numbered DST router Ethernet port LED lights. 
WiFi Settings
Make sure that the WiFi settings in the computer or WiFi device and DST \
router match 
exactly. The WiFi network name (SSID) and WiFi security settings of the DST rou\
ter and 
computer or WiFi device must match exactly. 
If you set up an access list on the Advanced Wireless Settings page, you must add each 
computer or WiFi device’
 s MAC address to the DST router’s access list.

 Nighthawk DST AC1900 DST Router and DST Adpater Model R7300DST
Network Settings
Make sure that the network settings of the computer are correct. Wired a\
nd wirelessly 
connected computers must use network (IP) addresses on the same networ\
k as the DST 
router. The simplest way to do this is to configure each computer to obtain an I\
P address 
automatically using DHCP. 
Some cable modem service providers require you to use the MAC address of\
 the computer 
initially registered on the account. 

You can view the MAC address in the Attached Devices 
page.
Troubleshoot With the LEDs
By default, the DST router is set with standard LED settings. If you dis\
abled blinking for the 
LEDs or turned off all LEDs except the Power LED, you must return the LEDs to their 
standard settings for troubleshooting. For information about controlling\
 the LED settings, see 
Disable DST Router LED Blinking or Turn Off LEDs  on page
  184.
Standard LED Behavior When the Router Is Powered On
After you turn on power to the DST router, verify that the following seq\
uence of events 
occurs:
1.  When power is first applied, verify that the Power LED 
 is lit.
2.  After approximately 30 seconds, verify the following:
• The Power LED is solid white.
• The Internet LED is lit.
• The WiFi LED is lit unless you turned of
 f the wireless radios.
You can use the LEDs on the front panel of the DST router for troubleshoo\
ting.
Power LED Is Off or Blinking
• Make sure that the power adapter is securely connected to your DST route\
r and securely 
connected to a working power outlet. 
• Check that you are using the power adapter that NETGEAR supplied for thi\
s product.
• If the Power LED blinks slowly and continuously
 , the DST router firmware is corrupted. 
This can happen if a firmware upgrade is interrupted, or if the DST rout\
er detects a  problem with the firmware. If the error persists, you have a hardware pr\
oblem. For 
recovery instructions, or help with a hardware problem, contact technica\
l support at 
netgear.com/support.

Power LED Stays Amber
When the DST router is turned on, the Power LED turns amber for about 20 seconds and 
then turns white. If the LED does not turn white, this indicates a problem with the DST router.
If the Power LED is still amber one minute after you turn on power to the DST router, do the 
following:
1. Turn off the power and then turn it back on to see if the DST router recovers.
2. Press and hold the Reset button to return the DST router to its factory settings. 
See Troubleshoot Your Network Using the Ping Utility on page 254.
If the error persists, a hardware problem might be the cause. Contact technical support at 
www.netgear.com/support.
LEDs Never Turn Off
When the DST router is turned on, the LEDs light for about 10 seconds and then turn off. If all 
the LEDs stay on, this indicates a fault within the DST router.
If all LEDs are still lit one minute after power-up, do the following:
•Cycle the power to see if the DST router recovers.
•Press and hold the Reset button to return the DST router to its factory settings. For more 
information, see 
Troubleshoot Your Network Using the Ping Utility on page 254.
If the error persists, you might have a hardware problem. Contact technical support at 
www.netgear.com/support.
Internet or Ethernet Port LEDs Are Off
If either the Ethernet port LEDs or the Internet LED does not light when the Ethernet 
connection is made, check the following:
•Make sure that the Ethernet cable connections are secure at the DST router and at the 
modem or computer.
•Make sure that power is turned on to the connected modem or computer.
•Be sure that you are using the correct cable.
When connecting the DST router’s Internet port to a cable or DSL modem, use the cable 
that was supplied with the cable or DSL modem. This cable can be a standard 
straight-through Ethernet cable or an Ethernet crossover cable.
Cannot Log In to the DST Router
If you are unable to log in to the DST router from a computer on your local network, check the 
following:
