Section 3 – Configuration D-Link DSL-2740R User Manual 38DNS 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 DNSrelay, 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 theISP 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 39in 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.
Section 3 – Configuration D-Link DSL-2740R User Manual 40VLAN To access the VLAN window, click the VLAN button in the Advanced directory. The Virtual LAN (VLAN) can group the devices even if they are not in thesame LAN segment. Select a number in the VLAN Index drop-down list, tick the Enable VLAN Group check box, .and tick the Port number and the corresponding tagged check boxes. Click the Add/Apply button to create the VLAN group.
Section 3 – Configuration D-Link DSL-2740R User Manual 41Firewall & 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 musthave 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 manuallyassign 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.
Section 3 – Configuration D-Link DSL-2740R User Manual 42Advanced ADSL To access the Advanced ADSL window, click the Advanced ADSL button in the Advanced directory.
