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 can’t connect
the device.
If your network topology has a loop, you need to enable the 802.1d
Spanning Tree function.
You don’t 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.

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.
Port Filtering
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.
46
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.
IP Filtering
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.
47
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.
MAC Filtering
When you enable the MAC Filtering function, you
Addresses in current filter table. If you select
forwarding default policy, once the source MAC
packets match the MAC Address definition in the
block those packets form LAN to WAN.
can specify the MAC
ACCEPT for the IP
Address of outgoing
table, the firewall will
48
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.
49
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.

Configuring DMZ
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.

After enabling the connecting profile, the system will check the preferred
SSID in a fixed period, if preferred APs are found; the radio will try to
connect with them one by one from top to down of the list and regardless
of the signal quality and strength. The users can put their most favorite AP
on the top so it will be connected first. Please note that check the
preferred APs will impact the throughput a lot! Unless the signal strength
is good enough, otherwise don't set the interval too short. The default
value is 10 minutes. And currently, all the profiles share the same security
setting.

“Delete Selected” and then click “OK” in the pop-up window to confirm it.

connecting profile”. The preferred AP list will be preserved for the next
use.
