WAN The WAN connection manages the WAN interfaces and addresses. Thus, the gateway can access the WAN. The parameters are described as follows: - Access Type: It displays the physical interfaces associated with the WAN connection, such as the DSL, Ethernet, and UMTS. - Service list: It is the service type carried by the WAN connection. You can select INTERNET, TR069, VOICE, or any combination of the preceding three types. - Virtual channel: It is the logical link when the access type is the DSL. You can configure up to four virtual channels and configure up to four WAN connections for each virtual channel. - VLAN: It is the logical link when the access type is the Ethernet. You can configure up to four VLANs and configure up to four WAN connections for each VLAN. When the access type is the DSL, you can also configure the VLAN. It indicates whether the packets sent from the WAN connection contain the VLAN identifier. - Port binding: It is used to specify which LAN ports and WLAN ports are bound to the WAN connection. The bound LAN ports and WLAN ports can access the network through only the designated WAN connection. - Connection mode: It is used to specify whether the WAN connection is in routing mode or in bridge mode. In routing mode, the IP address needs to be set or is set to be obtained automatically for the WAN connection. In bridge mode, the IP address needs to be set or is set to be obtained automatically only on the LAN side. - Connection type: It is the interface encapsulation type managed by the WAN connection. When the access type is the DSL, the gateway supports five routing modes: PPPoE, PPPoA, DHCP, Static, and IPoA and two bridge modes: IP_Bridged and PPP_Bridged. When the access type is the Ethernet, the gateway supports three routing modes: PPPoE, DHCP, and Static and two bridge modes: IP_Bridged and PPP_Bridged. When the access type is the UMTS, the gateway supports only the PPP-type routing mode. - DHCP transparent transmission: It is used to specify whether to perform the DHCP transparent transmission in bridge mode. If transparent transmission is set, the LAN devices can obtain the addresses of public networks through the bridge. Otherwise, the devices can obtain only the addresses of private networks assigned by the gateway. - NAT: It is used to specify whether to perform the IP address translation in routing mode. Through NAT, the LAN IP address can be translated into WAN IP address. Thus, the LAN devices with the IP addresses of private networks can access the network. 6

- NAT type: It is the NAT type. You can select NAPT or Cone NAT. If you select NAPT, one-to-one translation is performed between the LAN device and the public network. This translation is of high security. If you select Cone NAT, one-to-many translation is performed between the LAN device and the public network. This translation is of low security, but is easy for network communication. - User name: It is the user name used for identity authentication when the connection type is set to PPPoA, PPPoE, or PPP. - Password: It is the password used for the password authentication when the connection type is set to PPPoA, PPPoE, or PPP. - DHCP spoofing: When the connection type is set to PPPoA, PPPoE, or PPP, if this function is enabled, the IP addresses obtained from the WAN connection can be allocated to LAN devices through DHCP. Thus, for the LAN devices, a PPP network is regarded as a DHCP network. The advantage is that the LAN device does not need to be installed with a dial-up client when it obtains the addresses of public networks. - Authentication mode: It is the authentication mode when the connection type is set to PPPoA, PPPoE, or PPP. The RAP, CHAP, and Auto modes are supported. - Dialing method: It is the dialing method when the connection type is set to PPPoA, PPPoE, or PPP. The auto, manual, and on-demand dialing methods are supported. When the auto dialing method is selected, if the upstream link associated with the WAN connection is available, the gateway automatically starts dialing. If the dialing fails, the gateway retries automatically after an interval until the dialing succeeds. When the manual dialing method is selected, you need to manually start the dialing. If the dialing fails, the gateway automatically retries for another two times. If the dialing still fails, the gateway stops dialing. To access the network, you need to manually restart the dialing. When the on-demand dialing method is selected, if the gateway detects that you want to access the network, the gateway automatically starts dialing. If the network is not accessed during the idle time, the gateway automatically disconnects the dial-up connection. - Idle time: When the on-demand dialing method is selected, if the network is not accessed during this idle time, the gateway automatically disconnects the dial-up connection. - IP address: When the connection type is set to IPoA or Static, you need to manually set the static IP address. 7

LAN a) Host Settings on the LAN Side On this page, you can set the LAN-side parameters of the gateway, including the maintenance address, DHCP server parameters, access parameters of the WLAN, and MAC filtering parameters. After you set the IP address and subnet mask of the gateway on the LAN side, you should set the IP address of the host to be in the same network segment as that of the gateway, or you can configure the host to automatically obtain an IP address. Thus, the host can access the gateway properly. Assume that the IP address of the gateway is set to 192.168.0.1 and the subnet mask is set to 255.255.255.0. When the IP address of the host needs to be set manually, you need to set the IP address of the host to 192.168.0.x and set the subnet mask of the host to 255.255.255.0. In this case, the host can access the gateway properly. b) DHCP Server Settings Enable DHCP server: If you enable the DHCP server, the host on the LAN side can automatically obtain an IP address and a DNS address. Parameter settings of the DHCP server: - The start IP address and end IP address specify the range of IP addresses that can be allocated to the LAN devices by the primary address pool (default address pool) of the DHCP server. - The lease duration is specified when the DHCP server allocates an IP address to a LAN device. When the IP address is used by the LAN device for a period that reaches half of the lease duration, the LAN device should apply for the same IP address again. You can select a device type to perform the operations related to the secondary address pool and the DHCP relay. - The start IP address and end IP address of the secondary IP address pool specify the range of IP addresses that can be allocated to a certain type of devices. If you do not change this IP address pool, the DHCP server allocates IP addresses specified by the primary IP address pool by default. If you enable the DHCP relay, the specified LAN device can use the bridge mode (instead of the routing mode) on the WAN side of the gateway to automatically obtain an upstream public-network IP address on the WAN side. If you disable the DHCP relay, the LAN device can automatically obtain only a private-network IP address allocated by the DHCP server in the address pool. - The primary DNS server address is obtained by the LAN device when the device is set to automatically obtain an IP address. - The secondary DNS server address is obtained by the LAN device when the device is set to automatically obtain the IP address. If you set WAN-side address allocation mode to Transparent transmission and the LAN device is set to automatically obtain the IP address, the DHCP server can allocate the IP addresses obtained from the associated WAN interface to the device with the specified MAC address. If you do not specify the MAC address, the device can be any device on the LAN side by default. If you enable transparent transmission on the DHCP port and select a port on the LAN side, the LAN device can use the bridge mode (not the routing mode) on the WAN side of the gateway to automatically obtain an upstream public-network IP address on the WAN side. If you disable transparent transmission on the DHCP port, the LAN device can automatically obtain only a private-network IP address allocated by the DHCP server in the address pool. 8

WLAN WLAN Settings: Enable WLAN: It is used to specify whether to enable the WLAN. - Mode: It is used to select a working mode of the WLAN. You can select 802.11b, 802.11g, or 802.11b/g (that is the mixed mode). - Country code: It is used to select the country where the WLAN works. Then the channel list of the WLAN is generated based on the country that you set. - Country: When the country where the WLAN works is not in the country code list, you can enter the abbreviation of the country in this text box. - Channel: It is used to select an appropriate channel from the channel list based on the settings of the WLAN. To avoid signal interference, channels allocated to each AP should be different. You are recommended to select Auto. - Rate: It is used to select the working rate of the WLAN connection. If you select Auto, the gateway automatically selects the maximum appropriate rate based on the channel environment. T- ransmit power: It is the transmit power of the wireless RF module. - SSID index: It is the index of the current SSID. - SSID: You can enter any characters. The character string contains at most 32 characters and is case sensitive. - Maximum number of accessing devices: It is the maximum number of STAs that are allowed to access the current SSID. You can enter any number from 1 to 128. - Enable SSID: It is used to specify whether to enable the current SSID. - Hide broadcast: It is used to specify whether to enable the function of hiding the broadcast of the current SSID. If you enable this function, the gateway does not externally broadcast the information about the current SSID. - Enable QoS: It is used to specify whether to enable the QoS function of the current SSID. - AP isolation: It is used to specify whether to enable the AP isolation function of the current SSID. If you enable this function, the STAs with the current SSID cannot access each other. - Enable STA: It is used to specify whether to enable the STA function of the current SSID. 9

- Security: It is used to specify the security parameter of the current SSID. The gateway supports the open system, authentication modes, such as WEP, WPA-PSK, and WPA2-PSK, and corresponding encryption modes. - Enable WPS: It is used to specify whether to enable the WPS function. Restricted by the driver, only the first SSID provides the WPS function. - WPSmode: It is used to select the working mode of the WPS between PIN and pbc. - PIN: If you set the working mode of the WPS to PIN, enter the PIN generated by the client tool. WLAN MAC Address Filtering Enable MAC address filtering: It is used to specify whether to enable the function of filtering MAC addresses. - Filtering mode: It is used to select the mode for filtering the MAC addresses between blacklist and whitelist. If you select blacklist, the MAC addresses in the blacklist are not allowed to access the gateway. If you select whitelist, only the MAC addresses in the whitelist are allowed to access the gateway. - WLAN Filtering: The table displays the MAC addresses added to the list. - Source MAC address: It is used to specify the MAC address to be filtered. After you enter the MAC address, click Submit to add the MAC address to the list. 10

ADVANCED Routing Routing Firewall NAT DDNS IGMP QoS USB Port SNTP CWMP UPnP DLNA FTP Static Routing: To configure static routing, you can add a routing item to the primary routing table. Each routing item consists of three basic elements, including the destination network address, next-hop address, and local interface. You need to set Destination network address and Subnet mask. You can specify a next-hop address by setting Default gateway and a local transmission interface by setting Interface. Dynamic Routing: The gateway works in RIP dynamic routing mode. In dynamic routing mode, the gateway periodically sends (notifies) the information about the local routing table from a specified interface to the neighbor network node, such as a router, periodically receives the information about the latest routing table from the neighbor network node, and then updates the local routing table. If you set Operation to Active, the gateway receives the routing table information from the neighbor network node and also sends the routing table information to the neighbor network node. If you set Operation to Passive, the gateway only receives the routing table information but does not send the routing table information. The gateway supports the RIP in version 1 and version 2. You can set Version as required. 11

Firewall The firewall function can be classified into six sub-functions: MAC filtering, IP filtering, URL filtering, Application filtering, DOS attack, and ACL. The firewall level is a common property of the preceding six sub-functions. If you change the setting of the firewall level, the setting takes effect on all the six sub-functions. The firewall has seven levels: Disable, Block_All, High, Middle, Low, Standard, and Custom. To disable the firewall function, you can select Disable. The filtering degree of the firewall decreases in the sequence of Block_All, High, Middle, and Low. By default, the firewall level is set to Standard. The Other level is a customized level. In other words, you can customize the firewall level as required. Current level indicates the firewall level that is set currently. To set the firewall level, select a level from the Firewall level drop-down list box. If you select Custom, you should name the customized level and submit the settings. Then the customized level is displayed. You can customize multiple firewall levels. After selecting a customized firewall level, such as HGW, from the Firewall level drop-down list box, you can set, delete, and rename the level. In the conditions of predefined firewall levels (that is, except the customized firewall levels), the rules of all functional submodules are set based on firewall levels. MAC Filtering If you select the MAC filtering check box, the gateway filters the packets transmitted from the source MAC address to the destination MAC address. Through time control, the MAC filtering can be implemented during a specified period. When there are multiple filtering rules, you can define the priorities of these rules. When Disable is displayed in Status, it indicates that the rule is disabled. Accept indicates that the packets that conform to the rule are allowed to pass. Reject indicates that the packets that conform to the rule are not allowed to pass. IP Filtering If you select the IP filtering check box, the gateway filters the packets transmitted from the port range of the source IP address segment to the port range of the destination IP address segment. The protocol can be set to TCP, UDP, ICMP, or any of the combinations. The source IP address segment ranges from the source start address to the source end address; the source port range is from the source start port to the source end port; the destination IP address segment ranges from the destination start address to the destination end address; the destination port range is from the destination start port 12 to the destination end port. The interface indicates the direction from which the packet enters. You can define the

priorities of the filtering rules. When Disable is displayed in Status, it indicates that the rule is disabled. Accept indicates that the packets that conform to the rule are allowed to pass. Reject indicates that the packets that conform to the rule are not allowed to pass. URL Filtering If you select the URL filtering check box, the gateway controls the access to Web sites. A URL is the domain name of a Web site. You can define the priorities of the filtering rules. When Disable is displayed in Status, it indicates that the rule is disabled. Accept indicates that the packets that conform to the rule are allowed to pass. Reject indicates that the packets that conform to the rule are not allowed to pass. Application Filtering If you select the Application filtering check box, the gateway controls the access to applications, such as the FTP, SSH, and Telnet applications, which pass through the gateway. When Disable is displayed in Status, it indicates that the rule is disabled. Accept indicates that the packets that comply with the rule are allowed to pass. Reject indicates that the packets that conform to the rule are not allowed to pass. DOS Attack If you select the DOS attack check box, the gateway prevents the DOS attack from the external network to the internal network. The DOS attack includes the ICMP flooding attack, SYN flooding attack, and ARP attack. ACL If you select the ACL check box, the gateway controls the access from the LAN and the WAN to the gateway. A service type is the type of an application service. The access direction indicates that the access is initiated from the LAN or the WAN. The source IP address segment that can access the gateway ranges from the start IP address to the end IP address. The access control list (ACL) is a whitelist. In other words, all configured rules are allowed to be accessed by default. The general rule, however, is to reject all the application services in the drop-down list by default. 13

NAT ALG a) Introduction On this page, you can enable or disable multiple types of application level gateways (ALGs), such as the H.323 ALG, PPTP ALG, and L2TP ALG. b) Settings You can enable or disable the PPTP ALG. You can enable or disable the IPSec ALG. You can enable or disable the H.323 ALG. You can enable or disable the L2TP ALG. You can enable or disable the RTSP ALG. You can enable or disable the SIP ALG. DMZ a) Introduction If the demilitarized zone (DMZ) is enabled, the packets that are sent from the WAN and that cannot match any rule are sent to the computer on the LAN side for analysis or other uses, before the packets are discarded by the firewall. b) Operation For each WAN connection, you need to enter the IP address of the specified computer on the LAN side. Then enable the DMZ connected to the WAN. - Host address: It is the IP address of the specified computer on the LAN side. - Enable DMZ: It is used to specify whether to enable the DMZ of the WAN connection. 14

Port Mapping a) Introduction When NAT is enabled on the gateway, only the IP address on the WAN side is visible externally. When certain services, such as the FTP service, need to be enabled on a computer on the LAN side, the WAN-side port of the gateway needs to be redirected to the FTP port of the computer on the LAN side. Thus, the host on the WAN side can access the host on the LAN side through this WAN-side port. b) Operation You can select between two types of port mapping, that is, Customization and Application. For both types of port mapping, you should enter the IP address of the host on the LAN side. In other words, you need to specify the LAN-side host to which the services are mapped through the WAN-side port. - Interface: It is the interface name of the WAN connection. - Protocol: It is the protocol, such as TCP and UDP, supported by port mapping. - External port: It is the source port number used by the external network. - Internal port: It is the destination port number used by the internal network. - Internal host: It is the LAN-side host IP address to which the port is mapped. It is mandatory to set this parameter. - External source IP address: It is optional to set this parameter. If you enter the IP address, it indicates that only the WANside host with this IP address can be mapped to the LAN-side host through the port. - Mapping name: It is mandatory to set this parameter. 15

Port Triggering a) Introduction For certain P2P-type applications, when a LAN-side computer, such as computer1, connects to the port (called trigger port) of another computer, such as computer2, or a server, the application opens other ports (called open ports) of computer1 for the connection to computer 2 or other computers, thus implementing the sharing services and P2P-related services. b) Operation You can select between two types of port triggering, that is, Customization and Application. For both types of port triggering, it is mandatory to set Trigger start port, Open start port, and Trigger name. It is optional to set Trigger end port and Open end port. 16

DDNS When the IP address of the WAN interface is changed, the gateway automatically updates the relation between the domain name and the IP address. Thus, users of the external network can obtain the WAN interface address of the gateway through the domain name. The parameters are described as follows: - Service provider: It is the service provider that provides the services for updating dynamic domain names. - WAN connection: It is used to set up a relation between the domain name and the IP address of the WAN connection. - Domain: It is the domain specified by the domain-name service provider and is one part of the domain name. - Host: It is the only name in the specified domain. It can be applied for from the domain-name service provider and is one part of the domain name. - User name/email: It is the identity used to apply for the domain name. During the dynamic update of the domain name, the identity needs to be verified. - Password: It is the password used to apply for the domain name. During the dynamic update of the domain name, the password needs to be authenticated. - Server address: It is the server address of the domain-name service provider. - Server port: It is the server protocol port of the domain-name service provider. - Protocol: It is the server protocol of the domain-name service provider. IGMP Through the IGMP snooping function, the gateway performs the multicast management in the link layer and the packets that have multicast destination MAC addresses can be forwarded to the corresponding host or device. Through the IGMP proxy function, the gateway performs the multicast management in the network layer and a channel of multicast stream can be allocated to multiple hosts and devices, thus saving the network bandwidth. 17

QoS When the bandwidth is limited, through the QoS function, the gateway can allocate all the bandwidth to a certain application, increase the priority of the application. Global Settings On this page, you need to set certain global parameters of the QoS. The parameters are described as follows: - Enable: It is used to specify whether to enable the QoS function. - Bandwidth: It is used to specify the bandwidth used for the QoS. - Queue type: It is used to select a policy used for the QoS. The available types are described as follows: o PQ: If you set Queue type to PQ, four queues are listed based on the priorities. The priority is classified into the highest priority, high priority, medium priority, and low priority. The gateway first schedules the queue with a higher priority. If the queue with a higher priority has a packet cache, the queue with a lower priority cannot be scheduled. o WFQ: If you set Queue type to WFQ, four queues are listed. You can set the weight of the bandwidth occupied by each queue. The bandwidth is allocated to each queue based on the corresponding weight. o WFQ,PQ: If you set Queue type to WFQ,PQ, fore queues are listed. The first queue has the highest priority, The other queues scheduled by WFQ. Note: The templates have certain preset classification rules. After you select a template, you can modify the parameter settings of the template. - Queue: The parameters of the queue vary with queue types. You need to set the queue type in the global settings, and then set the corresponding queue parameters. For each queue type, all the queues can be enabled or disabled separately. - Policer: You can limit the rate of stream though configing the policer parameters. 18
