• Allows only one PC on the LAN

• The public IP address assigned by the remote side using the PPP/IPCP

protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the PC LAN interface through DHCP. Only one PC on the LAN can be connected to the remote, since the DHCP server within the device has only a single IP address to assign to a LAN device.

• NAT and firewall are disabled when this option is selected.

• The device becomes the default gateway and DNS server to the PC

through DHCP using the LAN interface IP address.

• The device extends the IP subnet at the remote service provider to the

LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.

• The device bridges the IP packets between WAN and LAN ports, unless

the packet is addressed to the device’s LAN IP address.

6.9 Port Mapping

Port Mapping supports multiple port to PVC and bridging groups. Each group will perform as an independent network. To support this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button. The Remove button will remove the grouping and add the ungrouped interfaces to the Default group. As shown below, when you tick the Enable virtual ports on, the LAN interfaces (eth0) in the default group will separate.

To add a port-mapping group, click the Add button.

To create a group from the list, first enter the group name and then select from the available interfaces on the list.

Automatically Add Clients With the Following DHCP Vendor IDs: Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID (option 60). The local DHCP server will decline and send the requests to a remote DHCP server by mapping the appropriate LAN interface. This will be turned on when PortMapping is enabled.

There are four PVCs (0/33, 0/36, 0/37, and 0/38). 0/33 is for PPPoE and the others are for IP setup-box (video). The LAN interfaces are eth0.1, eth0.2, eth0.3, eth0.4 and Wireless. Port mapping configuration is:

1. Default: eth0.1, eth0.2, eth0.3, eth0.4, Wireless, and Wireless_Guest.

2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video".

The CPE's DHCP server is now running on "Default". In addition, ISP's DHCP server is running on PVC 0/36. It is for setup-box use only.

On the LAN side, the PC can get an IP address from CPE's DHCP server and access the Internet via PPPoE (0/33).

If the setup-box was connected with interface "eth0.1" and sent a DHCP request with vendor id "Video", CPE's DHCP server will forward this request to ISP's DHCP server; and CPE will change the port-mapping configuration automatically. The port-mapping configuration will become:

1. Default: eth0.2, eth0.3, eth0.4, Wireless, and Wireless_Guest.

2. Video: nas_0_36, nas_0_37, nas_0_38, and eth0.1.

Network Authentication

This option specifies whether a network key is used for authentication to the wireless network. If network authentication is set to Open, then no authentication is provided. Despite this, the identity of the client is still verified.

Each authentication type has its own settings. For example, selecting 802.1X authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP Encryption will also be enabled as shown below.

The settings for WPA authentication are shown below.

The settings for WPA-PSK authentication are shown below.

WEP Encryption

This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined although only one can be used at any one time. Use the Current Network Key list box to select the appropriate network key.

Encryption Strength

This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the number of binary bits comprising the key. This means that keys with a are considerably more difficult to crack. Encryption strength can be set to either 64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10 hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26 hexadecimal numbers. FYI: Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data.

WPS

WPS is an industry standard that simplifies wireless security setup for certified network devices. Every WPS certified device has both a PIN number and a push button, located on the device or accessed through device software. This router has both a WPS button on the rear panel and a virtual button accessed from the web user interface (WUI).

Devices with the WPS logo (shown here) support WPS. However, the WPS logo might not be present on your device. In this case, check the device documentation for the phrase “Wi-Fi Protected Setup”.

NOTE: WPS is only available in WPA-PSK, WPA2-PSK or Mixed WPA2/WPA-PSK

network authentication modes. Other authentication modes do not use WPS so they must be configured manually.

To configure security settings with WPS, follow the procedure below. You must choose either the Push-Button or PIN configuration method for Steps 4 and 5.

A maximum of 60 MAC addresses can be added.

7.4 Wireless Bridge

This screen allows for the configuration of wireless bridge features of the WLAN interface. See the table beneath for detailed explanations of the various options. Click Save/Apply to implement new configuration settings.

AP Mode Description

Access Point Selecting Wireless Bridge (aka Wireless Distribution System)

disables Access Point (AP) functionality, while selecting Access

Point enables AP functionality. In Access Point mode, wireless

bridge functionality will still be available and wireless stations

will be able to associate to the AP. Bridge Restrict Selecting Disabled in Bridge Restrict disables wireless bridge

restriction, which means that any wireless bridge will be granted

access. Selecting Enabled or Enabled (Scan) enables wireless

bridge restriction. Only those bridges selected in Remote

Bridges will be granted access. Click Refresh to update the

station list when Bridge Restrict is enabled.

7.5 Advanced

The Advanced page allows you to configure advanced features of the WLAN interface. Among other things, you can select a particular channel on which to operate, force the transmission rate to a particular speed, set the fragmentation threshold, set the RTS threshold, set the wakeup interval for clients in power-save mode, set the beacon interval for the access point, set XPress mode and set whether short or long preambles are used.

Click Save/Apply to set new advanced wireless options.

Field Description

AP Isolation Select On or Off. By enabling this feature, wireless

clients associated with the Access Point can be linked.

Band The new amendment allows IEEE 802.11g units to fall back to

speeds of 11 Mbps, so IEEE 802.11b and IEEE 802.11g devices can coexist in the same network. The two standards apply to the 2.4 GHz frequency band. IEEE 802.11g creates data-rate parity at 2.4 GHz with the IEEE 802.11a standard, which has a 54 Mbps rate at 5 GHz. (IEEE 802.11a has other differences compared to IEEE 802.11b or g, such as offering more channels.)

Channel Allows selection of a specific channel (1-11) or Auto mode.

uses the maximum rate if possible but drops to lower rates

when necessary. The appropriate setting is dependent on signal

strength. Other rates are discrete values between 1 to 54 Mbps.

Fragmentation Threshold

A threshold, specified in bytes, that determines whether

packets will be fragmented and at what size. On an 802.11

WLAN, packets that exceed the fragmentation threshold are

split into smaller units suitable for the circuit size. Packets

smaller than the specified fragmentation threshold value are

not fragmented.

Values between 256 and 2346 can be entered. The value should

remain at its default setting of 2346, if possible, since setting

the Fragmentation Threshold too low may result in poor

performance. If you experience a high packet error rate, try to

slightly increase the Fragmentation Threshold. RTS Threshold Request to Send, set in bytes, specifies the packet size beyond

which the WLAN Card invokes its RTS/CTS mechanism. Packets

that exceed the specified RTS threshold trigger the RTS/CTS

mechanism. Smaller packets are sent without using RTS/CTS.

The default setting of 2347 (maximum length) disables RTS

Threshold altogether. DTIM Interval Delivery Traffic Indication Message (DTIM) is also known as

Beacon Rate. The entry range is a value between 1 and 65535.

A DTIM is a countdown variable that informs clients of the next

window for listening to broadcast and multicast messages.

When the AP has buffered broadcast or multicast messages for

associated clients, it sends the next DTIM with a DTIM Interval

value. AP Clients hear the beacons and awaken to receive the

broadcast and multicast messages. The default is 1. Beacon Interval The amount of time between beacon transmissions in

milliseconds. The default is 100 ms and the acceptable range is

1 – 65535. The beacon transmissions identify the presence of

an access point. By default, network devices passively scan all

RF channels listening for beacons coming from access points.

Before a station enters power save mode, the station needs the

beacon interval to know when to wake up to receive the beacon

(and learn whether there are buffered frames at the access

point). Maximum Associated

you may also try 802.11b only mode. 54g Protection In Auto mode, the router will use RTS/CTS to improve 802.11g

performance in mixed 802.11g/802.11b networks. Turning

protection Off will maximize 802.11g throughput under most

conditions. Preamble Type Short preamble is intended for applications where maximum

7.6 Quality of Service

WMM provides advanced quality of service (QoS) features for Wi-Fi networks to improve the end-user experience by prioritizing audio, video and voice traffic and optimizing the way shared network resources are allocated among competing applications. To enable WMM, select Enabled in the WMM (Wi-Fi Multimedia) drop down list box. The screen will display as shown below.

Field Description

WMM (Wi-Fi Multimedia)

WMM No Acknowledge ment

To add an Extended Wireless QoS Classification, click Add QoS Entry. The following screen will display.

This technology maintains the priority of audio, video and voice applications in a Wi-Fi network. It ensures that multimedia services get higher priority. Refers to the acknowledge policy used at the MAC level. Enabling no Acknowledgement can result in more efficient throughput but higher error rates in a noisy Radio Frequency (RF) environment.

Enter a Traffic Class Name and assign the Wireless Transmit Priority from the drop-down list box. Specify Traffic Classification Rules by choosing the desired parameters under this heading. Click Save/Apply to add the Wireless QoS rule.

When finished adding rules, click Save/Apply WME Settings on the main screen.

7.7 Station Info

NOTE: The default settings can be found in section 3.1 Default Settings.

After the Restore Default Configuration button is selected, the following screen appears. Close the device Configuration window and wait for 2 minutes before reopening the browser. If necessary, reconfigure your PC IP address to match your new configuration (see section 3.2 IP Configuration for details).

After a successful reboot, the browser will return to the Device Info screen. If the browser does not refresh to the default screen, close and restart the browser.

NOTE: The Restore Default function has the same effect as the reset button. The

device board hardware and the boot loader support the reset to default button. If the reset button is continuously pushed for more than 5 seconds (and not more than 12 seconds), the boot loader will erase the configuration settings saved on flash memory.

9.2 System Log

The System Log option under Management allows for the viewing of system events and configuration of related options. The default setting for the System Log is enabled. Follow the steps below to enable and view the System Log.

STEP 1: Click Configure System Log to begin.

Step 2: Select the system log options (see table below) and click Save/Apply.

Field Description

Log Indicates whether the system is currently recording

events. The user can enable or disable event logging. By default, it is disabled.

Log level Allows you to configure the event level and filter out

unwanted events below this level. The events ranging from the highest critical level “Emergency” down to this configured level will be recorded to the log buffer. When the log buffer is full, the newer event will wrap up to the top of the log buffer and overwrite the old event. By default, the log level is “Debugging” which is the lowest critical level. The log levels are defined as follows:

• Emergency = system is unusable

• Alert = action must be taken immediately

• Critical = critical conditions

• Error = Error conditions

• Warning = normal but significant condition

• Notice= normal but insignificant condition

• Informational= provides information for reference

• Debugging = debug-level messages

Emergency is the most serious event level, whereas Debugging is the least important. For instance, if the log level is set to Debugging, all the events from the lowest Debugging level to the most critical level Emergency level will be recorded. If the log level is set to Error, only Error and the level above will be logged.

Display Level Allows the user to select the logged events and displays

on the View System Log window for events of this level and above to the highest Emergency level.

Mode Allows you to specify whether events should be stored in

the local memory, or be sent to a remote syslog server or both simultaneously. If remote mode is selected, view system log will not be able to display events saved in the remote syslog server. When either Remote mode or Both modes are configured, the WEB UI will prompt the user to enter the Server IP address and Server UDP port.

close the browser, wait for two minutes, and then restart the WUI.

If this does not work, then press the reset button on the rear panel of the

device for 5-7 seconds to restore to default settings.

Appendix A: Security

Stateful Packet Inspection

Refers to an architecture, where the firewall keeps track of packets on each connection traversing all its interfaces and makes sure they are valid. This is in contrast to static packet filtering which only examines a packet based on the information in the packet header.

Denial of Service Attack

Is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have. Various DoS attacks the device can withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf Attack, and Tear Drop.

TCP/IP/Port/Interface Filter

These rules help in the filtering of traffic at the Network layer i.e. Layer 3. When a Routing interface is created, Enable Firewall must be checked. Navigate to Advanced Setup -> Security -> IP Filtering.

Outgoing IP Filter

Helps in setting rules to DROP packets from the LAN interface. By default if Firewall is Enabled all IP traffic from LAN is allowed. By setting up one or more filters, particular packet types coming from the LAN can be dropped.

Filter Name: User defined Filter Name.

Protocol: Can take on any values from: TCP/UDP, TCP, UDP or ICMP

Source IP Address/Source Subnet Mask: Packets with the particular “Source IP Address/Source Subnet Mask" combination will be dropped.

Source Port: This can take on either a single port number or a range of port

numbers. Packets having a source port equal to this value or falling within the range of port numbers (portX : portY) will be dropped.

Destination IP Address/Destination Subnet Mask: Packets with the particular "Destination IP Address/Destination Subnet Mask" combination will be dropped.

Destination Port: This can take on either a single port number or a range of port numbers. Packets having a destination port equal to this value or falling within the range of port numbers (portX : portY) will be dropped.

Example 1:

Filter Name : Out_Filter1 Protocol : TCP Source Address : 192.168.1.45 Source Subnet Mask : 255.255.255.0 Source Port : 80 Destination Address : NA Destination Subnet Mask : NA Destination Port : NA

This filter will Drop all TCP packets coming from LAN with IP Address/Sub. Mask

192.168.1.45/24 having a source port of 80 irrespective of the destination. All other packets will be Accepted.

Example 2:

Filter Name : Out_Filter2 Protocol : UDP Source Address : 192.168.1.45 Source Subnet Mask : 255.255.255.0 Source Port : 5060:6060 Destination Address : 172.16.13.4 Destination Subnet Mask : 255.255.255.0 Destination Port : 6060:7070

This filter will drop all UDP packets coming from LAN with IP Address/ Subnet Mask

192.168.1.45/24 and a source port in the range of 5060 to 6060, destined to

172.16.13.4/24 and a destination port in the range of 6060 to 7070.

Incoming IP Filtering:

Helps in setting rules to ACCEPT packets from the WAN interface. By default, all incoming IP traffic from the WAN is Blocked, if the Firewall is Enabled. By setting up one or more filters, particular packet types coming from the WAN can be Accepted.

Filter Name: User defined Filter Name.

Protocol: Can take on any values from TCP/UDP, TCP, UDP or ICMP

Source IP Address/Source Subnet Mask: Packets with the particular "Source IP

Address/Source Subnet Mask" combination will be accepted.

Source Port: This can take on either a single port number or a range of port numbers. Packets having a source port equal to this value or falling within the range of port numbers (portX : portY) will be accepted.

Destination IP Address/Destination Subnet Mask: Packets with the particular "Destination IP Address/Destination Subnet Mask" combination will be accepted.

The WAN interface on which these rules apply needs to be selected by user.

Example 1:

Filter Name : In_Filter1 Protocol : TCP Source Address : 210.168.219.45 Source Subnet Mask : 255.255.0.0 Source Port : 80 Destination Address : NA Destination Submask : NA Destination Port : NA

Selected WAN interface: mer_0_35/nas_0_35

This filter will ACCEPT all TCP packets coming from WAN interface mer_0_35/nas_0_35 with IP Address/Sub. Mask 210.168.219.45/16 having a source port of 80 irrespective of the destination. All other incoming packets on this interface are DROPPED.

Example 2:

Filter Name : In_Filter2 Protocol : UDP Source Address : 210.168.219.45 Source Subnet Mask : 255.255.0.0 Source Port : 5060:6060 Destination Address : 192.168.1.45 Destination Subnet Mask : 255.255.255.0 Destination Port : 6060:7070

This rule will ACCEPT all UDP packets coming from WAN interface mer_0_35/nas_0_35 with IP Address/Subnet Mask 210.168.219.45/16 and a source port in the range of 5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range of 6060 to 7070. All other incoming packets on this interface are DROPPED.

MAC Layer Filtering: These rules help in the filtering of traffic at the Layer 2. MAC Filtering is only effective on ATM PVCs configured in Bridge mode. After a Bridge mode PVC is created, navigate to Advanced Setup - Security - MAC Filtering.

Global Policy: When set to Forwarded the default filter behavior is to Forward all MAC layer frames except those explicitly stated in the rules. Setting it to Blocked changes the default filter behavior to Drop all MAC layer frames except those explicitly stated in the rules.

Protocol Type: Either PPPoE, IPv4, IPv6, AppleTalk, IPX, NetBEUI, IGMP.

Destination MAC Address: Of the form, XX:XX:XX:XX:XX:XX. Frames with this

particular destination address will be Forwarded/Dropped depending on whether the Global Policy is Blocked/Forwarded.

Source MAC Address: Of the form, XX:XX:XX:XX:XX:XX. Frames with this particular source address will be Forwarded/Dropped depending on whether the Global Policy is Blocked/Forwarded.

Frame Direction: (User must select interface on which this rule is applied)

LAN <=> WAN --> All Frames coming/going to/from LAN or to/from WAN. WAN => LAN --> All Frames coming from WAN destined to LAN. LAN => WAN --> All Frames coming from LAN destined to WAN

Example 1:

Global Policy: Forwarded Protocol Type: PPPoE Destination MAC Address: 00:12:34:56:78:90 Source MAC Address: NA Frame Direction: LAN => WAN WAN Interface Selected: br_0_34/nas_0_34

Addition of this rule drops all PPPoE frames going from LAN-side to WAN-side with a Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC Address on the br_0_34 WAN interface. All other frames on this interface are forwarded.

Example 2:

Global Policy: Blocked Protocol Type: PPPoE Destination MAC Addr: 00:12:34:56:78:90 Source MAC Addr: 00:34:12:78:90:56 Frame Direction: WAN => LAN WAN Interface Selected: br_0_34/nas_0_34

Addition of this rule forwards all PPPoE frames going from WAN-side to LAN-side with a Destination MAC Address of 00:12:34:56:78 and Source MAC Address of 00:34:12:78:90:56 on the br_0_34 WAN interface. All other frames on this interface are dropped.

Daytime Parental Control

This feature restricts access of a selected LAN device to an outside Network through the device, as per chosen days of the week and the chosen times.

User Name: Name of the Filter.

Browser MAC Address: Displays MAC address of the LAN device on which the

browser is running.

Other MAC Address: If restrictions are to be applied to a device other than the one on which the browser is running, the MAC address of that LAN device is entered.

Days of the Week: Days of the week, when the restrictions are applied.

Start Blocking Time: The time when restrictions on the LAN device begin.

End Blocking Time: The time when LAN device restrictions are lifted.

Example:

User Name: FilterJohn Browser's MAC Address: 00:25:46:78:63:21 Days of the Week: Mon, Wed, Fri Start Blocking Time: 14:00 End Blocking Time: 18:00

When this rule i.e. FilterJohn is entered, a LAN device with MAC Address of 00:25:46:78:63:21 will be restricted access to the outside network on Mondays, Wednesdays, and Fridays, from 2pm to 6pm. On all other days and time, this device will have access to the outside Network.
