Here  you  can  see  a  list  of  wireless
                                                                            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.
