1.1 Safety Precautions
Take the following instructions to prevent the device from risks and damage caused by fire or electric power:
Use the type of power marked in the volume label. Use the power adapter in the product package. Pay attention to the power load of the outlet or prolonged lines. An
overburden power outlet or damaged lines or plugs may cause electric shock or fire accidents. Check the power cords regularly. If you find any damage, replace it at once.
Proper space left for heat dissipation is necessary to avoid damage caused
by overheating to the device. The long and thin holes on the device are designed for heat dissipation to ensure that the device works normally. Do not cover these heat dissipation holes.
Do not put this device close to a heat source or under a high temperature
occurs. Keep the device away from direct sunshine.

Configure the Start Match Port, End Match Port , Trigger Protocol, Start Relate Port, End Relate Port, Open Protocol and Nat type. Click the Apply changes button to finish.
3.3.4 Port Forwarding
This function is used to open ports in your device and redirect data through those ports to a single PC on your network (WAN-to-LAN traffic). It allows remote users to access services on your LAN, such as FTP for file transfers or SMTP and POP3 for e-mail. The device accepts remote requests for these services at your global IP address. It uses the specified TCP or UDP protocol and port number, and redirects these requests to the server on your LAN with the LAN IP address you specify. Note that the specified private IP address must be within the available range of the subnet where the device is in. Choose Advanced > Port Forwarding. The page shown in the following figure appears.

Configure the Protocol, WAN Setting, WAN Interface, WAN Port, LAN Open Port and LAN IP Address. Click the Apply changes button to finish.
3.3.5 DMZ
DMZ is the abbreviation of the Demilitarized Zone. Since some applications are
not compatible with NAT, the device supports the use of a DMZ IP address for a single host on the LAN. This IP address is not protected by NAT and it is visible to agents on the Internet with the correct type of software. Note that any client PC in
Page 62
56
the DMZ is exposed to various types of security risks. If you use the DMZ, take measures (such as client-based virus protection) to protect the remaining client PCs on your LAN from possible contamination through DMZ. Choose Advanced > DMZ. The page shown in the following figure appears.
In the DMZ Host IP Address, input the LAN IP address of the LAN computer that you want to have unrestricted Internet communication. If this computer obtains its address automatically using DHCP, then you may want to make a static reservation on the Setup-->Local Network-->DHCP Reserved page so that the IP address of the DMZ computer does not change. Click Apply to save the settings.
3.3.6 Parental Control
Y ou may create a list of websites that you would like the devices on your network to be denied access to. URL Block allows you to quickly create a list of all websites that you wish to stop users from accessing.

3.3.7 Filtering Options
Filters can be configured to manage your incoming and outgoing traffic.
3.3.7.1 IP/Port Filter
When you use the Port Triggering or Port Forwarding features to open specific ports to traffic from the Internet, you could be increasing the exposure of your LAN
Page 67
61
to cyber attacks from the Internet. In these cases, you can limit that exposure by specifying the IP addresses of Internet hosts that you trust to access your LAN through the ports that you have opened. Choose Advanced > Filtering Options > IP/Port Filter. The IP/Port Filtering page shown in the following figure appears.
Direction Upstream (Dow nstream) means packets outgoing (incoming) from (to) router. The Source IP addresses are LAN-side (WAN-side) addresses and the Destination IP addresses are WAN-side (LAN-side) addresses. Select the rule

3.3.10 Dynamic DNS
The device supports dynamic domain name service (DDNS). The dynamic DNS service allows a dynamic public IP address to be associated with a static host
Page 74
68
name in any of the many domains, and allows access to a specified host from various locations on the Internet. Click a hyperlinked URL in the form of hostname.dyndns.org and allow remote access to a host. Many ISPs assign public IP addresses using DHCP, so locating a specific host on the LAN using the standard DNS is difficult. For example, if you are running a public web server or VPN server on your LAN, DDNS ensures that the host can be located from the Internet even if the public IP address changes. DDNS requires that an account be set up with one of the supported DDNS service providers (DyndDNS.org or dlinkddns.com). Choose Advanced > Dynamic DNS. The Dynamic DNS Configuration page shown in the following page appears.

3.3.11 Network Tools
The router provides following tools: Port Mapping, IGMP Proxy, IP QoS, UPnP, SNMP, TR-069, Software Forbidden, ARP Bindi nd, and Client Limit.
3.3.11.1 Port Mapping
Port Mapping supports a single (LAN) port or multiple (LAN) ports to be formed as a group and mapped to a PVC (which is associated w/ a VLAN). As a result, each group of LAN ports will perform as an independent (logical) network (like a broadcast domain) among whom traffic broadcast would be prevented. This feature is useful while you would like to form multiple independent (logical) networks for multimedia applications at home. For instance, you can map PVC1 to port 1~3 to create a network (broadcast domain) for PCs for Internet, and map PVC2 to port 4 to create another network (broadcast domain) for IPTV service (devices). By using this feature (w/ multiple PVCs), data traffic and IPTV traffic would not affect each other. Choose Advanced > Network Tools > Port Mapping. The Port Mapping Configuration page shown in the following figure appears.
Page 76

Step 3 Click Apply button to save the changes.
Note:
The selected interfaces will be removed from their existing groups and added to the new group.
3.3.11.2 IGMP Proxy
IGMP allows support for efficient multicasting -- transmission of identical content, such as multimedia, from a source to a number of recipients. IGMP proxy enables the system to issue IGMP host messages on behalf of hosts that the system discovered through standard IGMP interfaces. The system acts as a proxy for its hosts when you enable it. Choose Advanced > Network Tools > IGMP Proxy. The IGMP Proxy Configuration page shown in the following figure appears.
Page 78
72
The following table describes the parameters and buttons of this page.
Field Description

be xmitted. Last Member Query Count
This parameter specifies the times the device sends
the query message. Query Interval
The device sends query messages to check IGMP
user periodically. The unit is second. Query Response Interval
The device waits for the IGMP user’s reply . The unit is
100 * millisecond.
Group Leave Delay

multicast packets after a corresponding IGMP "Leave
Group" message has been successfully offered to the
modem.
Click Apply Changes to save the settings.
