Before Start to Configure
There are two ways to configure the device, one is through web-browser, and the other is through Secure Shell CLI interface. To access the configuration interfaces, make sure you are using a computer connected to the same network as the device. The default IP address of the device is 192.168.2.254, and the subnet-mask is 255.255.255.0. The device has three operation modes (Router/Bridge/WISP). In bridge mode, also known as AP Client, you can access the device by both WLAN (Wireless Local Area Network) and wired LAN. And in router/WISP modes, the device can be accessed by both WLAN and WAN. The default IP addresses for the device are 192.168.2.254(for LAN), 18.104.22.168(for WAN), so you need to make sure the IP address of your PC is in the same subnet as the device, such as 192.168.2.X (for LAN), 172.1.1.X (for WAN). Please note that the DHCP server inside the device is default to up and running. Do not have multiple DHCP servers in your network environment, otherwise it will cause abnormal situation. We also provide an auto-discovery tool which is for finding out the IP of the device. In case, youve forgot the IP of the device or the IP of the device has been changed, you can use the tool to find out the IP of the device even your PC is not in the same subnet as the device is.

Ch 3. Configuring WDS
Wireless Distribution System (WDS) uses wireless media to communicate with the other devices, like the Ethernet does. This function allows one or more remote LANs connect with the local LAN. To do this, you must set these devices in the same channel and set MAC address of other devices you want to communicate with in the WDS AP List and then enable the WDS. When you decide to use the WDS to extend your WLAN, please refer the following instructions for configuration. The bridging devices by WDS must use the same radio channel. When the WDS function is enabled, all wireless stations cant connect the device. If your network topology has a loop, you need to enable the 802.1d Spanning Tree function. You dont need to add all MAC address of devices existed in your network to WDS AP List. WDS AP List only needs to specify the MAC address of devices you need to directly connect to. The bandwidth of device is limited, to add more bridging devices will split the more bandwidth to every bridging device.
WDS network topology
In this section, we will demonstrate the WDS network topologies and WDS AP List configuration. You can setup the four kinds of network topologies: bus, star, ring and mesh. In this case, there are five devices with WDS enabled: WDS1, WDS2, WDS3, WDS4 and WDS5. Bus topology:

You must set these connected devices with the same radio channel, but you may use different SSID. Choose WDS mode for only wireless backbone extension purpose. You can use any network topology, please refer the WDS topology section.
Ch 4. Advanced Configurations
Configuring LAN to WAN Firewall
Filtering function is used to block or permit packets from LAN to WAN. The device supports three kinds of filter Port Filtering, IP Filtering and MAC Filtering. All the entries in current filter table are used to restrict or allow certain types of packets from your local network to through the device. Use of such filters can be helpful in securing or restricting your local network. Denied or Allowed list depends on your IP forwarding default policy in Route page. The IP forwarding default policy is ACCEPT. If you want block some application from LAN to WAN, you can go to Route page to select ACCEPT for IP Forwarding Default Policy.
If you want permit some application from LAN to WAN, you can go to Route page to select DROP for IP Forwarding Default Policy.
When you enable the Port Filtering function, you can specify a single port or port ranges in current filter table. If you select ACCEPT for the IP forwarding default policy, once the source port of outgoing packets match the port definition or within the port ranges in the table, the firewall will block those packets form LAN to WAN.
If you select DROP for the IP forwarding default policy, once the source port of outgoing packets match the port definition or within the port ranges in the table, the firewall will allow those packets form LAN to WAN.
When you enable the IP Filtering function, you can specify local IP Addresses in current filter table. If you select ACCEPT for the IP forwarding default policy, once the source IP address of outgoing packets match the IP address definition in the table, the firewall will block those packets form LAN to WAN.
If you select DROP for the IP forwarding default policy, once the source IP address of outgoing packets match the IP address definition in the table, the firewall will allow those packets form LAN to WAN.
When you enable the MAC Filtering function, you can specify the MAC Addresses in current filter table. If you select ACCEPT for the IP forwarding default policy, once the source MAC Address of outgoing packets match the MAC Address definition in the table, the firewall will block those packets form LAN to WAN.
If you select DROP for the IP forwarding default policy, once the source MAC Address of outgoing packets match the MAC Address definition in the table, the firewall will allow those packets form LAN to WAN.
NAT (Network Address Translation)
NAT is the translation between public IP address and private IP address. While NAT is enabling, you can use port forwarding or DMZ to redirect your common network services. If you want to disable NAT, you can go to Management-Route page to disable it and the functions of DMZ, Port Forwarding will be disabled.
Configuring Port Forwarding (Virtual Server)
This function allows you to automatically redirect common network services to a specific machine behind the NAT firewall. These settings are only necessary if you wish to host some sort of server like a web server or mail server on the private local network behind the device's NAT firewall.
The most often used port numbers are shown in the following table.
Services ECHO FTP (File Transfer Protocol) Telnet SMTP (Simple Mail Transfer Protocol) DNS (Domain Name System) Finger HTTP (Hyper Text Transfer Protocol) POP3 (Post Protocol) NNTP (Network News Transport Protocol) SNMP (Simple Network Management Protocol) SNMP trap SIP (Session Initiation Protocol) PPTP (Point-to-Point Tunneling Protocol) Port Number 1723
About the other well-known ports, please search in http://www.iana.org/assignments/port-numbers.
Multiple Servers behind NAT Example:
In this case, there are two PCs in the local network accessible for outside users.
A Demilitarized Zone is used to provide Internet services without sacrificing unauthorized access to its local private network. Typically, the DMZ host contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers. So that all inbound packets will be redirected to the computer you set. It also is useful while you run some applications (ex. Internet game) that use uncertain incoming ports.
Enable DMZ: DMZ Host IP Address:
Enable the Enable DMZ, and then click Apply Changes button to save the changes. Input the IP Address of the computer that you want to expose to Internet. 51
Configuring WAN Interface
The device supports four kinds of IP configuration for WAN interface, including Static IP, DHCP Client, PPPoE and PPTP. You can select one of the WAN Access Types depend on your ISP required. The default WAN Access Type is Static IP.
You can get the IP configuration data of Static-IP from your ISP. And you will need to fill the fields of IP address, subnet mask, gateway address, and one of the DNS addresses.
Subnet Mask: Default Gateway:
The Internet Protocol (IP) address of WAN interface provided by your ISP or MIS. The address will be your network identifier besides your local network. The number used to identify the IP subnet network, indicating whether the IP address can be recognized on the LAN or if it must be reached through a gateway. The IP address of Default Gateway provided by your ISP or MIS. Default Gateway is the intermediate network device that has knowledge of the network IDs of the other networks in the Wide Area Network, so it can forward the packets to other gateways until they are delivered to the one connected to the specified destination. The IP addresses of DNS provided by your ISP. DNS (Domain Name Server) is used to map domain names to IP addresses. DNS maintain central lists of domain name/IP addresses and map the domain names in your Internet requests to other servers on the Internet until the specified web site is found. Clone device MAC address to the specify MAC address required by your ISP Enable uPnP, this function allows the device to be found and configured automatically by the system. (Ex. Window XP)
