Port Forwarding
Port Forwarding Rules menu
To enable an already existing Port Forwarding Rule, click on its corresponding
checkbox and configure the appropriate fields listed below. To configure other
Port Forwarding Rules for the Router, configure the following fields and click
the Save Settings button at the top of the window.
To view the following window, click on the Advanced tab at the top of the window and
then click the Port Forwarding button to the left. This window will allow remote users
access to various services outside of their LAN through a public IP address, such as FTP
(File Transfer Protocol) or HTTPS (Secure Web). After configuring the Router for these
features, the Router will redirect these external services to an appropriate server on the users
LAN. The Router has 13 pre-configured external services already set, but the user may add
alternate services using the window above. The Port Forwarding Rules listed in the
following window are:
• FTP – File Transfer Protocol, used to transfer large files over the Internet
• HTTP – HyperText Transfer Protocol, the basic protocol of the World Wide Web
• HTTPS – HyperText Transfer Protocol Secure, the basic protocol of the World
Wide Web with added security provided by the Secure Shell feature (SSH)
• DNS – Domain Name Server, a server that translates website addresses into IP
addresses
• SMTP – Simple Mail Transfer Protocol, used to transmit e-mail messages between
parties
• POP3 – Post Office Protocol version 3, used to retrieve e-mail from a mail server
• Telnet – A terminal emulation program used for remote configuration
• IP Sec – IP Security, used for a secure transfer of information over the network. If
one end of the transmission is using IPSec, so must the other end
• PPTP – Point to Point Tunneling Protocol, used to transfer information securely
between VPNs (Virtual Private Routers)
• NetMeeting – An application that allows teleconferences over the Internet
• DCS–1000 – A D-Link internet camera used for security monitoring
• DCS–2000/DCS–5300 – A D-Link internet camera used for security monitoring
• i2eye – A D-Link Broadband VideoPhone used for video conferencing
These external services may be modified by clicking the corresponding checkbox. Though
there are seven fields available to configure the Port Forwarding Rules, in most cases, only
the IP address will be needed for implementation. For more information on configuring Port
Forwarding Rules, otherwise known as Virtual Servers, see the window below, along with a
brief explanation of the fields to be configured.
