DNS Setup
To access the DNS Setup window, click the DNS Setup button in the Advanced directory.
The Router can be configured to relay DNS settings from your ISP or
another available service to workstations on your LAN. When using DNS
relay, the Router will accept DNS requests from hosts on the LAN and
forward them to the ISP’s, or alternative DNS servers. DNS relay can
use auto discovery or the DNS IP address can be manually entered by
the user. Alternatively, you may also disable the DNS relay and
configure hosts on your LAN to use DNS servers directly. Most users
who are using the Router for DHCP service on the LAN and are using
DNS servers on the ISP’s network, will leave DNS relay enabled (either
auto discovery or user configured).
If you have not been given specific DNS server IP addresses or if the
Router is not pre-configured with DNS server information, select the
“Obtain DNS server address automatically” option. Auto discovery DNS
instructs the Router to automatically obtain the DNS IP address from the
ISP through DHCP. If your WAN connection uses a Static IP address,
auto discovery for DNS cannot be used.
If you have DNS IP addresses provided by your ISP, click the “Use the
following DNS server addresses” radio button and enter these IP
addresses in the available entry fields for the Preferred DNS Server and
the Alternative DNS Server. When you have configured the DNS
settings as desired, click the Apply Settings button and then click the
Reboot button on the left panel to let your changes take effect.
The Router supports DDNS (Dynamic Domain Name Service). The
Dynamic DNS service allows a dynamic public IP address to be
associated with a static host name in any of the many domains, allowing
access to a specified host from various locations on the Internet. This is
enabled to allow remote access to a host by clicking a hyperlinked URL
Section 3 – Configuration
D-Link DSL-2740R User Manual 39
in the form hostname.dyndns.org, Many ISPs assign public IP addresses using DHCP, this can make it difficult to locate a specific host on the LAN
using standard DNS. If for example you are running a public web server or VPN server on your LAN, this ensures that the host can be located from
the Internet if the public IP address changes. DDNS requires that an account be setup with one of the supported DDNS providers.
Tick the Enable Dynamic DNS check box, enter the required DDNS information, click the Apply Settings button, and then click the Reboot button
on the left panel to let your changes take effect to set this information in the Router.
Note
DDNS requires that an account be setup with one of the supported DDNS servers prior to engaging it on the Router. This function will not work without an accepted
account with a DDNS server.

Firewall & DMZ
To access the Firewall & DMZ window, click the Firewall & DMZ button in the Advanced directory.
Firewalls may conflict with certain interactive applications such as video
conferencing or playing Internet video games. For these applications, a
firewall bypass can be set up using a DMZ IP address. The DMZ IP
address is a “visible” address and does not benefit from the full
protection of the firewall function. Therefore it is advisable that other
security precautions be enabled to protect the other computers and
devices on the LAN. It may be wise to use isolate the device with the
DMZ IP address from the rest of the LAN.
If you want to use video conferencing, for example, and still use a
firewall, you can use the DMZ IP address function. In this case, you must
have a PC or server through which video conferencing will take place.
The IP address of this PC or server will then be the DMZ IP address. You
can designate the server’s IP address as the DMZ by going to the DMZ
Settings section and typing in the IP address in the IP Address field
provided and then enabling its status by ticking the Enable DMZ
checkbox, clicking Apply Settings, and then clicking the Reboot button
on the left panel to let your changes take effect.
For the system that uses the DMZ IP address, you may want to manually
assign an IP address to it and adjust your DHCP server addresses so
that the DMZ IP address is not included in the DHCP server range. This
way you avoid possible IP address problems if you reboot the DMZ
system.
The Firewall Settings section allows the Router to enforce specific
predefined policies intended to protect against certain common types of
attacks. Tick the Enable Firewall check box, and click the Apply
Settings button to active the function.
