46 III Features & Configurations | Tenda devices (if any) connected to the device. Tip ① The Bandwidth here refers to the channel bandwidth instead of wireless connection rate. ② You can know whether there are unauthorized accesses to your wireless network by viewing this connection status list.
47 III Features & Configurations | Tenda 4 Advanced Applications This section includes the following:  To remotely access the device via a domain name or access a server on a LAN PC, see 4.1 DDNS Settings.  To let an Internet user access your LAN PC without any restriction, see 4.2 DMZ Host.  To automatically map the ports between WAN and LAN, see 4.3 UPNP.  To enable the remote Web management feature, see 4.4 Remote Web Management.  To regulate bandwidth, see 4.5 Bandwidth Control (Available only in 4G600).  To restrict your LAN PCs to access certain services on the Internet via their IP addresses, see 4.6 Client Filter (Available only in 4G600). 4.1 DDNS Settings Dynamic DNS or DDNS is a term used for the updating in real time of Internet Domain Name System (DNS) name servers. We use a numeric IP address allocated by Internet Service Provider (ISP) to connect to the Internet; the address may either be stable ("static"), or may change from one session on the Internet to the next ("dynamic"). However, a numeric address is inconvenient to remember; an address which changes unpredictably makes connection impossible. The DDNS provider allocates a static host name to the user; whenever the user is allocated a new IP address this is communicated to the DDNS provider by software running on a computer or network device at that address; the provider distributes the association between the host name and the address to the Internet's DNS servers so that they may resolve DNS queries. Thus, uninterrupted access to devices and services whose numeric IP address may change is maintained. Click Advanced -> DDNS Settings to enter the screen below.
48 III Features & Configurations | Tenda Tip To use the DDNS feature, you need to have an account with one of the DDNS Service Providers in the drop-down list first. DDNS Application Example: If your ISP gives you a dynamic (changing) public IP address, you want to access your router remotely (see 4.4 Remote Web Management) but you cannot predict what your router's WAN IP address will be, and the address can change frequently. In this case, you can use a commercial Dynamic DNS service. It lets you register your domain to their IP address and forwards traffic directed at your domain to your frequently changing IP address. If your DDNS service provider provides you with a DDNS account (User Name: tenda, Password: 123456, Domain Name: tenda.dyndns.org) and you want to use the PC at the IP address of 218.88.93.33 to remotely access this device on the port number of 8090. Then follow the steps below: ① DDNS Settings: Check the Enable DDNS box. ② DDNS Service Provider: Select your DDNS service provider from the drop-down list. Here in this example, select dyndns.org. ③ User Name: Enter the DDNS user name you have registered with your
49 III Features & Configurations | Tenda DDNS service provider. Here in this example, enter tenda. ④ Password: Enter the DDNS Password you have registered with your DDNS service provider. Here in this example, enter 123456. ⑤ Domain Name: Enter the DDNS domain name you have registered with your DDNS service provider. Here in this example, enter tenda.dyndns.org. ⑥ Click Save to save your settings. ⑦ Click Remote Web Management, enable the Remote Web Management feature, enter 8090 in the Port field, 218.88.93.33 in the IP Address field and then click Save to save your settings. Now, you can access your device from the Internet by typing your device’s domain name into your browser ’s address or location field on yo ur PC
50 III Features & Configurations | Tenda (218.88.93.33) followed by a colon (:) and the remote management port number. Here in this example, enter http://tenda.dyndns.org:8090. 4.2 DMZ Host The DMZ (De-Militarized Zone) function disables the firewall on the router for one device for a special purpose service such as Internet gaming or video conferencing applications that are not compatible with NAT (Network Address Translation). Click Advanced -> DMZ Host to enter the screen below. Note ① DMZ host poses a security risk. A computer configured as the DMZ host loses much of the protection of the firewall and becomes vulnerable to attacks from external networks. ② Hackers may use the DMZ host computer to attack other computers on your network. Configuration Procedures: ① DMZ Host IP: The IP address of the device for which the router ’s firewall
51 III Features & Configurations | Tenda will be disabled. Be sure to statically set the IP address of the device that serves as a DMZ host for this function to be consistent. ② Enable: Check to enable the DMZ host functionality. ③ Click Save to save your settings. Tip Security softwares such as anti-virus softwares and OS built-in firewall, etc. may affect the DMZ host feature. Disable them if the DMZ host fails. 4.3 UPNP The Universal Plug and Play (UPnP) feature allows network devices, such as computers from the Internet, to access resources on local host or devices as needed. UPnP-enabled devices can be discovered automatically by the UPnP service application on the LAN. If you use applications such as multiplayer gaming, peer-to-peer connections, real-time communications such as instant messaging, or remote assistance (a feature in Windows XP), you may need to enable Universal Plug and Play (UPnP) for better experience. Click Advanced -> UPnP to enter the configuration screen. The UPnP feature is enabled by default.
52 III Features & Configurations | Tenda 4.4 Remote Web Management The Remote Web Management allows the device to be configured and managed remotely from the Internet via a Web browser. Click Advanced -> Remote Web Management to enter the configuration screen. Tip ① For better security, configure a port number (between 1025 and 65535) as the remote Web management interface, do not use the number of any common service port (1~1024). ② Make sure your WAN IP address (Internet IP address) is a public IP address. Private IP addresses are not routed on the Internet. ③ It is unsafe to make your router remotely accessible to all PCs on external network. For the purpose of security, we suggest that you only enter the IP address of the PC that is to be used to remotely manage your device. Remote Web Management Application Example: To access your device (WAN IP address: 102.33.66.88) at your home from the
53 III Features & Configurations | Tenda PC (218.88.93.33) at your office via the port number of 8090, follow the steps below: ① Enable: Check to enable the remote Web management feature. ② Port: Enter 8090. ③ IP Address: Specify the IP address for remote management. Here in this example, enter 218.88.93.33. ④ Click Save to save your settings. Type "http://102.33.66.88:8090" into your browser’s address or location field and you can remotely access the router from your home. Knowledge Center IP Address: Here you can specify the IP address for remote management (If set to "0.0.0.0", the device becomes remotely accessible to all the PCs on the Internet or other external networks). Port: This is the management port to be open to outside access. The default setting is 8080. This can be changed. 4.5 Bandwidth Control (Available only in 4G600) If there are multiple PCs behind your device competing for limited bandwidth resource, then you can use this feature to specify a reasonable amount of
54 III Features & Configurations | Tenda bandwidth for each such PC, so that no one will be over stuffed or starved to death. Note that this feature is unavailable in 3G/4G Router Mode. Bandwidth Control Application Example: You share a 4M-broadband service with your neighbor (at the IP address of 192.168.0.125). He always downloads a large volume of data from the Internet, which sharply frustrates your Internet surfing experience; you can use this feature to set limits for the volume of Internet traffic he can get. For example, you can equally split the bandwidth, so your neighbor can only use up to 2M Internet traffic and you can smoothly enjoy 2M. Configuration Procedures: ① Bandwidth Control: Check the Enable box to enable the feature. ② IP Address: Enter the last number of the IP address. Here in this example, enter 125 in both boxes. ③ Upload Limit: Set a limit to regulate the uplink bandwidth of PC(s) on the LAN. Here in this example, enter 32 in both boxes. ④ Download Limit: Set a limit to regulate the downlink bandwidth of PC(s) on the LAN. Here in this example, enter 256 in both boxes. ⑤ Enable: Check to enable the current rule. ⑥ Add to List: Click to add the current rule to the rule list. ⑦ Click Save to save your settings.
55 III Features & Configurations | Tenda Tip ① 1M=128KByte/s. ② The volume of uplink traffic/downlink traffic should not be larger than that allowed on your device's WAN (Internet) port. Consult your ISP, if you are not sure of the total volume of Internet traffic that you can have. ③ The bandwidth for ADSL/DSL line usually refers to the download bandwidth. 4.6 Client Filter (Available only in 4G600) This section allows you to set the times specific clients can or cannot access the Internet via the devices’ IP addresses and service port. Note that this feature is unavailable in 3G/4G Router Mode.
56 III Features & Configurations | Tenda Knowledge Center Default: The default policy for the client filter. For the packets that do not match the set rule, the default rule is applied. Filter Mode: Specify a filter mode for the rule.  Deny: Disallow the packets that match the set rule to pass the router. For other packets that do not match the set rule, the default policy is applied.  Allow: Allow the packets that match the set rule to pass the router. For other packets that do not match the set rule, the default policy is applied. Client Filter Application Example: To prohibit PCs within the IP address range of 192.168.0.110--192.168.0.111 from accessing Web pages during the time period of 8:00~18:00 from Monday to Friday, follow the steps below: ① Click Add to add a filter rule. ② Filter Mode: Select Deny. ③ Description: Briefly describe the current rule. This field is optional. ④ IP: Enter 192.168.0.110 as the starting IP address and 192.168.0.111 as the ending IP address.
57 III Features & Configurations | Tenda ⑤ WAN Port Range: Enter a service port number. Here in this example, enter 80 in both boxes. HTTP port 80 is the standard protocol for Web servers. ⑥ Type: Select a protocol for the traffic. If you are unsure, select Both. ⑦ Time: Specify a time period for the current rule to take effect. Here in this example, select 8:00~18:00. Day: Select a day, or several days of the week for the current rule to take effect.
