expired, the user will be automatically assigned a new dynamic IP address. The default is
259200 seconds.
• Physical Ports: Specify the Physical Ports of the DHCP client.
• DNS Relay: If you want to disable this feature, you just need to set both Primary and
secondary DNS IP to 0.0.0.0. If you want to use DNS relay, you can setup DNS server IP
to 192.168.1.1 on their Computer. If not, the device will perform as no DNS relay.
• Primary DNS Server: Type in your preferred DNS server.
• Secondary DNS Server: Type in your preferred DNS server.
• Current Pool Summary: Click the button, then you can view the IP addresses that the
DHCP Server gives out.
) Note:
If Use Auto Discovered DNS Server Only is selected in DNS Relay, this router will accept the
first received DNS assignment from one of the PPPoA, PPPoE or MER/DHCP enabled PVC(s)
during the connection establishment. If Use User Discovered DNS Server Only is selected in
DNS Relay, it is necessary for you to enter the primary and optional secondary DNS server IP
addresses. After type in the address, click SAVE button to save it and invoke it.
¾ DHCP Relay: Select Relay, then you will see the next screen (shown in Figure 4-13), and the
Router will work as a DHCP Relay. A DHCP relay is a computer that forwards DHCP data
between computers that request IP addresses and the DHCP server that assigns the
addresses. Each of the device's interfaces can be configured as a DHCP relay. If it is enabled,
the DHCP requests from local PCs will forward to the DHCP server runs on WAN side. To
have this function working properly, please run on router mode only, disable the DHCP server
on the LAN port, and make sure the routing table has the correct routing entry.

rules to allow wireless-equipped computers and other devices to communicate with a wireless
network.
• Access point: Select Activated to allow wireless station to associate with the access
point.
• Channel: Select your region and the channel you want to use from the drop-down List of
Channel. This field determines which operating frequency will be used. It is not
necessary to change the default channel unless you notice interference problems with
another nearby access point.
• Transmit Power: Here you can specify the transmit power of Router. You can select
High, Medium or Low which you would like. High is the default setting and is
recommended.
• Beacon Interval: Enter a value between 20-1000 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. A beacon is a packet broadcast by
the Router to synchronize the wireless network. The default value is 100.
• RTS/CTS Threshold: Should you encounter inconsistent data flow, only minor reduction
of the default value 2347 is recommended. If a network packet is smaller than the preset
RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends
Request to Send (RTS) frames to a particular receiving station and negotiates the
sending of a data frame. After receiving an RTS, the wireless station responds with a
Clear to Send (CTS) frame to acknowledge the right to begin transmission. In most cases,
keep its default value of 2347.
• Fragmentation Threshold: This value specifies the maximum size for a packet before
data is fragmented into multiple packets. If you experience a high packet error rate, you
may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold
too low may result in poor network performance. Only minor reduction of the default value
is recommended. In most cases, it should remain at its default value of 2346.
• DTIM: This value, between 1 and 255, indicates the interval of the Delivery Traffic
Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next
window for listening to broadcast and multicast messages. When the Router has buffered
broadcast or multicast messages for associated clients, it sends the next DTIM with a
DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast
and multicast messages. The default value is 1.
• Wireless Mode: In the drop-down list you can select “802.11b”, “802.11g”, “802.11n”,
“802.11b+g”, “802.11g+n” and “802.11b+g+n”. “802.11b+g+n” allows 802.11b, 802.11g

Virtual LAN (VLAN) is a group of devices on one or more LANs that are configured so that they
can communicate as if they were attached to the same LAN, when in fact they are located on a
number of different LAN segments. Because VLANs are based on logical instead of physical
connections, it is very flexible for user/host management, bandwidth allocation and resource
optimization. There are two types of VLAN as follows:
Port-Based VLAN: Each physical switch port is configured with an access list specifying
membership in a set of VLANs.
ATM VLAN: Using LAN Emulation (LANE) protocol to map Ethernet packets into ATM cells and
deliver them to their destination by converting an Ethernet MAC address into an ATM address.
