Application Example: Making 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.
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 screen, 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 configure your router to
use the name as described in
73. To access your web server from
the Internet, a remote user has to know the IP address that your ISP assigned. However, if
you use a Dynamic DNS service, the remote user can reach your server by a user-friendly
Internet name, such as mynetgear.dyndns.org.
Set Up Port Triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
•
More than one local computer needs port forwarding for the same application (but not
simultaneously).
•
An application needs to open incoming ports that are different from the outgoing port.
When port triggering is enabled, the router monitors outbound traffic looking for a specified
outbound “trigger” port. When the router detects outbound traffic on that port, it remembers
outbound “trigger” port. When the router detects outbound traffic on that port, it remembers
