The router lists default services and applications that you can use in port forwarding rules. If the service or application
is not predefined, you can add a port forwarding rule with a custom service or application. To add a port forwarding rule with a custom service or application: 1.
Find out which port number or range of numbers the service or application uses.
You can usually find this information by contacting the publisher of the service or application or through user
groups or news groups.

							Application Example: Make a Local Web Server Public
If you host a web server on your local network, you can use port forwarding to allow web requests from anyone on
the Internet to reach your web server.
To make a local web server public: 1.
Assign your web server either a fixed IP address or a dynamic IP address using DHCP address reservation.
In this example, your router always gives your web server an IP address of 192.168.1.33.
2. On the Port Forwarding / Port Triggering page, configure the router to forward the HTTP service to the local
address of your web server at 192.168.1.33.
HTTP (port 80) is the standard protocol for web servers.
3. (Optional) Register a host name with a Dynamic DNS service, and specify that name on the Dynamic DNS page
of the router.
Dynamic DNS makes it much easier to access a server from the Internet because you can enter the name in
the web browser. Otherwise, you must know the IP address that the ISP assigned, which typically changes.
How the Router Implements the Port Forwarding Rule
The following sequence shows the effects of a port forwarding rule:
1. When you enter the URL www.example.com in your browser, the browser sends a web page request message
with the following destination information:
•Destination address. The IP address of www.example.com, which is the address of your router.
• Destination por

t number
. 80, which is the standard port number for a web server process.
2. The router receives the message and finds your port forwarding rule for incoming port 80 traffic.
3. The router changes the destination IP address in the message to 192.168.\
1.123 and sends the message to that
computer.
4. Your web server at IP address 192.168.1.123 receives the request and sends a reply message to your router.
5. Your router performs Network Address Translation (NAT) on the source IP address and sends the reply through
the Internet to the computer or WiFi device that sent the web page request.
Manage Port Triggering for Services and Applications Port triggering is a dynamic extension of port forwarding that is useful in these cases:
•An application must use port forwarding to more than one local computer (but not simultaneously).
• An application must open incoming ports that are different from the outgoing port. Manage Port Forwarding and Port Triggering
225
Nighthawk AC1900 Smart WiFi Router Model R6900 
						

							With port triggering, the router monitors traffic to the Internet from an outbound “trigger” port that you specify. For
outbound traffic from that port, the router saves the IP address of the computer that sent the traffic. The router
temporarily opens the incoming port or ports that you specify in your rule and forwards that incoming traffic to that
destination.
Port forwarding creates a static mapping of a port number or range of ports to a single local computer. Port triggering
can dynamically open ports to any computer when needed and close the ports when they are no longer needed.
If you use applications such as multiplayer gaming, peer-to-peer connections, real-time
communications such as instant messaging, or remote assistance, enable Universal Plug and
Play (UPnP). See Improve Network Connections With Universal Plug and Play on page 68.
Note
Add a Port Triggering Rule
The router does not provide default services and applications for port triggering rules. You must define a custom
ser

vice or application for each port triggering rule.

Launch a web browser from a computer or WiFi device that is connected to the network.
2. Enter 
http://www.routerlogin.net.
A login window opens.
