The Applications and Gaming Tab - Single Port Forward
Single Port Forward. Certain applications may require to open specific ports in order for it to function correctly.
Examples of these applications include servers and certain online games. Basically, this sets up public services
on your network, such as web servers, ftp servers, e-mail servers, or other specialized Internet applications.
(Specialized Internet applications are any applications that use Internet access to perform functions such as
videoconferencing or online gaming. Some Internet applications may not require any forwarding.)
When users send this type of request to your network via the Internet, the Router will forward those requests to
the appropriate PC. Any PC whose port is being forwarded must have its DHCP client function disabled and must
have a new static IP address assigned to it because its IP address may change when using the DHCP function.
Applications. Ten applications are preset. For custom applications, enter the name of your application in one of
the available fields.
The preset applications are among the most widely used Internet applications. They include the following:
FTP (File Transfer Protocol). A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). For
example, after developing the HTML pages for a website on a local machine, they are typically uploaded to the
web server using FTP.
