DHCP Server Settings

DHCP stands for Dynamic Host Control Protocol. The router has a built-in DHCP server. The DHCP Server will automatically assign an IP
address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting their TCP/IP settings
to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load the proper TCP/IP settings provided
by the DGL-4500. The DHCP Server will automatically allocate an unused IP address from the IP address pool to the requesting computer.
You must specify the starting and ending address of the IP address pool.

This feature allows the configuration of a NetBIOS ‘domain’ name under which network hosts operates. This setting has no

Section 3 - Configuration

Virtual Server

The DGL-4500 can be configured as a virtual server so that remote users accessing Web or FTP services via the public
IP address can be automatically redirected to local servers in the LAN (Local Area Network).

The DGL-4500 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked
with the DGL-4500 are invisible to the outside world. If you wish, you can make some of the LAN computers accessible
from the Internet by enabling Virtual Server. Depending on the requested service, the DGL-4500 redirects the external
service request to the appropriate server within the LAN network.

The DGL-4500 is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to a
different port on the server computer.

Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are
pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to
use that particular virtual service.

For a list of ports for common applications, please visit http://support.dlink.com/faq/view.asp?prod_id=1191.

Application Rules

Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and
others. These applications have difficulties working through NAT (Network Address Translation). Special Applications
makes some of these applications work with the DGL-4500. If you need to run applications that require multiple
connections, specify the port normally associated with an application in the “Trigger Port” field, select the protocol type
as TCP or UDP, then enter the firewall (public) ports associated with the trigger port to open them for inbound traffic.

The DGL-4500 provides some predefined applications in the table on the bottom of the web page. Select the application
you want to use and enable it.

may define a single port or a range of ports.
You can use a comma to add multiple ports or
port ranges.

GameFuel settings are disabled and application priority is not classified automatically.

Speed:

Manual Uplink

Speed:

This option is disabled by default. Enable this option for better
performance and experience with online games and other
interactive applications, such as VoIP.

This option is enabled by default. This will allow your router
to automatically determine the network priority of running
programs.

This option should be enabled when you have a slow Internet
uplink. It helps to reduce the impact that large low priority
network packets can have on more urgent ones.

This option is enabled by default when the GameFuel option
is enabled. This option will allow your router to automatically
determine the uplink speed of your Internet connection.

This displays the detected uplink speed.

The speed at which data can be transferred from the router
to your ISP. This is determined by your ISP. ISP’s often speed
as a download/upload pair. For example, 1.5Mbits/284Kbits.
Using this example, you would enter 284. Alternatively you can
test your uplink speed with a service such as www.dslreports.
com.

Connection Type:

By default, the router automatically determines whether the underlying connection is an xDSL/Frame-relay network or some
other connection type (such as cable modem or Ethernet), and it displays the result as Detected xDSL or Frame Relay Network.

36D-Link DGL-4500 User Manual

Section 3 - Configuration

If you have an unusual network connection in which you are actually connected via xDSL but for which you configure either
“Static” or “DHCP” in the Internet settings, setting this option to xDSL or Other Frame Relay Network ensures that the router
will recognize that it needs to shape traffic slightly differently in order to give the best performance. Choosing xDSL or Other
Frame Relay Network causes the measured uplink speed to be reported slightly lower than before on such connections, but
gives much better results.

Detected xDSL:

When Connection Type is set to automatic, the automatically detected connection type is displayed here.
