Check this box to enable the DHCP server on your router. Uncheck to

disable this function.

Enter the starting and ending IP addresses for the DHCP server’s IP

assignment.

Note:

If you statically (manually) assign IP addresses to your computers

or devices, make sure the IP addresses are outside of this range or you

may have an IP conﬂict.

The length of time for the IP address lease. Enter the Lease time in

minutes.

Enable this feature to broadcast your networks DHCP server to LAN/

WLAN clients.

NetBIOS allows LAN hosts to discover all other computers within the

network, enable this feature to allow the DHCP Server to offer NetBIOS

conﬁguration settings.

Enable this feature to allow WINS information to be learned from the WAN side, disable to allow manual conﬁguration.

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

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.

DHCP Reservation

If you want a computer or device to always have the same IP address assigned, you can create a DHCP reservation.

The router will assign the IP address only to that computer or device.

Note:

This IP address must be within the DHCP IP Address Range.

Check this box to enable the reservation.

Enter the computer name or select from the

D-Link DGL-4500 User Manual

Section ³ - Conﬁguration

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.

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.
