Port Forwarding to a Local Server

If your home network includes a server, you can allow certain types of incoming traffic to

reach the server. For example, you might want to make a local web server, FTP server, or

game server visible and available to the Internet.

The router can forward incoming traffic with specific protocols to computers on your local

network. You can specify the servers for applications and you can also specify a default DMZ

server to which the router forwards all other incoming protocols.

Set Up Port Forwarding to a Local Server



To forward specific incoming protocols:

1.

Decide which type of service, application, or game you want to provide.

2.

Find the local IP address of the computer on your network that will provide the service.

The server computer must always use the same IP address. To specify this setting, use

the reserved IP address feature. See

Manage Reserved LAN IP Addresses

on page

3.

Launch a web browser from a computer or mobile device that is connected to your Orbi

network.

4.

Enter

orbilogin.com

.

A login window opens.

5.

Enter the router admin user name and password.

The user name is

admin

. The default password is

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.

In 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 type the name in the Internet 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 type 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 port number

. 80, which is the standard port number for a web server

process.

2.

Your router receives the message and finds your port forwarding rule for incoming port 80

traffic.

3.

The router changes the destination in the message to IP address 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.

Port Triggering

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.

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.

1.

Launch a web browser from a computer or mobile device that is connected to your Orbi

network.

2.
