Chapter 3 Web User Interface
This section describes how to access the device via the web user interface (WUI) using an Internet browser such as Internet Explorer (version 5.0 and later).
3.1 Default Settings
The factory default settings of this device are summarized below.
LAN IP address: 192.168.1.1
LAN subnet mask: 255.255.255.0
Administrative access (username: root , password: 12345 )
User access (username: user , password: user )
Remote (WAN) access (username: support , password: support )
WLAN access: enabled
Technical Note
During power on, the device initializes all settings to default values. It will then read the configuration profile from the permanent storage section of flash memory.
The default attributes are overwritten when identical attributes with different values are configured. The configuration profile in permanent storage can be created via the web user interface or telnet user interface, or other management protocols.
The factory default configuration can be restored either by pushing the reset button for more than ten seconds until the power indicates LED blinking or by clicking the
Restore Default Configuration option in the Restore Settings screen.
11
3.2 IP Configuration
DHCP MODE
When the NexusLink 3241u/3241eu powers up, the onboard DHCP server will switch on. Basically, the DHCP server issues and reserves IP addresses for LAN devices, such as your PC.
To obtain an IP address from the DCHP server, follow the steps provided below.
NOTE: The following procedure assumes you are running Windows. However, the general steps involved are similar for most operating systems (OS).
Check your OS support documentation for further details.
STEP 1 : From the Network Connections window, open Local Area Connection ( You may also access this screen by double-clicking the Local Area Connection icon on your taskbar ). Click the Properties button.
STEP 2 : Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Select Obtain an IP address automatically as shown below.
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.
12
STATIC IP MODE
In static IP mode, you assign IP settings to your PC manually.
Follow these steps to configure your PC IP address to use subnet 192.168.1.x.
NOTE: The following procedure assumes you are running Windows. However, the general steps involved are similar for most operating systems (OS).
Check your OS support documentation for further details.
STEP 1 : From the Network Connections window, open Local Area Connection ( You may also access this screen by double-clicking the Local Area Connection icon on your taskbar ). Click the Properties button.
STEP 2 : Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Change the IP address to the 192.168.1.x (1<x<255) subnet with subnet mask of 255.255.255.0. The screen should now display as shown below.
STEP 4: Click OK to submit these settings.
13
3.3 Login Procedure
Perform the following steps to login to the web user interface.
NOTE: The default settings can be found in section 3.1 Default Settings .
STEP 1: Start the Internet browser and enter the default IP address for the device in the Web address field. For example, if the default IP address is
192.168.1.1, type http://192.168.1.1.

5.17 Interface Grouping
Interface Grouping supports multiple ports to PVC and bridging groups. Each group performs as an independent network. To use this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button.
The Remove button removes mapping groups, returning the ungrouped interfaces to the Default group. Only the default group has an IP interface.
To add an Interface Group, click the Add button. The following screen will appear.
It lists the available and grouped interfaces. Follow the instructions shown onscreen.
87
Automatically Add Clients With 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
Interface Grouping is enabled.
88
For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are
ENET1, ENET2, ENET3, and ENET4.
The Interface Grouping configuration will be:
1. Default: ENET1, ENET2, ENET3, and ENET4.
2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video".
If the onboard DHCP server is running on "Default" and the remote DHCP server is running on PVC 0/36 (i.e. for set-top box use only). LAN side clients can get IP addresses from the CPE's DHCP server and access the Internet via PPPoE (0/33).
If a set-top box is connected to ENET1 and sends a DHCP request with vendor ID
"Video", the local DHCP server will forward this request to the remote DHCP server.
The Interface Grouping configuration will automatically change to the following:
1. Default: ENET2, ENET3, and ENET4
2. Video: nas_0_36, nas_0_37, nas_0_38, and ENET1.

The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface.
Please see 6.3
for WPS setup instructions.
Click Apply/Save to implement new configuration settings.
WIRELESS SECURITY
Setup requires that the user configure these settings using the Web User Interface
(see the table below).
Select SSID
Select the wireless network name from the drop-down menu. SSID stands for
Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that client will not be granted access.
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.
Different authentication type pops up different settings requests.
107
Choosing 802.1X
, enter RADIUS Server IP address, RADIUS Port, RADIUS key and
Current Network Key.
Also, enable WEP Encryption and select Encryption Strength.
Select the Current Network Key and enter 13 ASCII characters or 26 hexadecimal digits for 128-bit encryption keys and enter 5 ASCII characters or 10 hexadecimal digits for 64-bit encryption keys.
Choosing WPA2-PSK , you must enter WPA Pre-Shared Key and Group Rekey
Interval.
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.
Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.11 networks from unauthorized access, such as eavesdropping; in this case, the capture of wireless network traffic.
108
When data encryption is enabled, secret shared encryption keys are generated and used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers.
Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel.
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 greater number of bits have a greater degree of security and 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. Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data.
109
6.3 WPS 5GHz
Wi-Fi Protected Setup (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. The NexusLink 3241u/3241eu has a WPS button on the device.
Devices with the WPS logo (shown here) support WPS. If the WPS logo is not present on your device it still may support WPS, in this case, check the device documentation for the phrase “Wi-Fi Protected Setup”.
NOTE: WPS is only available in Open, WPA-PSK, WPA2-PSK and 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 procedures below.
I. Setup
Step 1: Enable WPS by selecting Enabled from the drop down list box shown.
Step 2: Set the WPS AP Mode. Configured is used when the NexusLink
3241u/3241eu will assign security settings to clients. Unconfigured is used when an external client assigns security settings to the NexusLink
3241u/3241eu.
NOTES: Your client may or may not have the ability to provide security settings to the NexusLink 3241u/3241eu. If it does not, then you must set the WPS
AP mode to Configured. Consult the device documentation to check its capabilities.
110
IIa. PUSH-BUTTON CONFIGURATION
The WPS push-button configuration provides a semi-automated configuration method. The WPS button on the front panel of the router can be used for this purpose.
The WPS push-button configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless Access Point (AP) of your WLAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled.
NOTE: The wireless AP on the router searches for 2 minutes. If the router stops searching before you complete Step 4, return to Step 3.
Step 3: Press WPS button
Press the WPS button on the front panel of the router. The WPS LED will
blink to show that the router has begun searching for the client.
Step 4: Go to your WPS wireless client and activate the push-button function.
A typical WPS client screenshot is shown below as an example.
Now go to Step 7 (part III. Check Connection) to check the WPS connection.
IIb. WPS – PIN CONFIGURATION
Using this method, security settings are configured with a personal identification number (PIN). The PIN can be found on the device itself or within the software.
The PIN may be generated randomly in the latter case. To obtain a PIN number for your client, check the device documentation for specific instructions.
The WPS PIN configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless
Access Point (AP) of your wireless LAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled.
Step 5: Select the PIN radio button in the WSC Setup section of the Wireless
Security screen, as shown in A or B below, and then click the appropriate button based on the WSC AP mode selected in step 2.
A For Configured mode, click the Add Enrollee button.
111
Enter STA PIN : a Personal Identification Number (PIN) has to be read from either a sticker or the display on the new wireless device. This PIN must then be inputted at representing the network, usually the Access Point of the network.
B - For Unconfigured mode, click the Config AP button.
Step 6: Activate the PIN function on the wireless client. For Configured mode, the client must be configured as an Enrollee. For Unconfigured mode, the client must be configured as the Registrar. This is different from the
External Registrar function provided in Windows Vista.
The figure below provides an example of a WPS client PIN function in-progress.
III. CHECK CONNECTION
Step 7: If the WPS setup method was successful, you will be able access the wireless AP from the client. The client software should show the status.
The example below shows that the connection established successfully.
You can also double-click the Wireless Network Connection icon from the
Network Connections window (or the system tray) to confirm the status of the new connection.

Field
Fragmentation
Threshold
RTS Threshold
Description
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 fragmented, i.e., split into, smaller units suitable for the circuit size. Packets smaller than the specified fragmentation threshold value are not fragmented. Enter a value between 256 and 2346. If you experience a high packet error rate, try to slightly increase your Fragmentation Threshold. The value should remain at its default setting of 2346. Setting the Fragmentation
Threshold too low may result in poor performance.
Request to Send, when 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. The NIC transmits smaller packet without using RTS/CTS. The default setting of 2347 (maximum length) disables RTS
Threshold.
DTIM Interval
Beacon 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.
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).
Global Max Clients The maximum number of clients that can connect to the router.

6.10 Security 2.4GHz
The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface.
Please see 6.11
for WPS setup instructions.
Click Apply/Save to implement new configuration settings.
WIRELESS SECURITY
Setup requires that the user configure these settings using the Web User Interface
(see the table below).
Select SSID
Select the wireless network name from the drop-down menu. SSID stands for
Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that client will not be granted access.
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.
125
Different authentication type pops up different settings requests.
Choosing 802.1X
, enter RADIUS Server IP address, RADIUS Port, RADIUS key and
Current Network Key.
Also, enable WEP Encryption and select Encryption Strength.
Select the Current Network Key and enter 13 ASCII characters or 26 hexadecimal digits for 128-bit encryption keys and enter 5 ASCII characters or 10 hexadecimal digits for 64-bit encryption keys.
Choosing WPA2-PSK , you must enter WPA/WAPI passphrase and Group Rekey
Interval.
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.
Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.11 networks from unauthorized access, such as eavesdropping; in this case, the capture of wireless network traffic.
126
When data encryption is enabled, secret shared encryption keys are generated and used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers.
Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel.
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 greater number of bits have a greater degree of security and 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. Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data.
127
6.11 WPS 2.4GHz
Wi-Fi Protected Setup (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. The NexusLink 3241u/3241eu has a WPS button on the device.
Devices with the WPS logo (shown here) support WPS. If the WPS logo is not present on your device it still may support WPS, in this case, check the device documentation for the phrase “Wi-Fi Protected Setup”.
NOTE: WPS is available in Open, WPA2-PSK and 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 procedures below.
I. Setup
Step 1: Enable WPS by selecting Enabled from the drop down list box shown.
Step 2: Set the WPS AP Mode. Configured is used when the NexusLink
3241u/3241eu will assign security settings to clients. Unconfigured is used when an external client assigns security settings to the NexusLink
3241u/3241eu. Then click the Apply/Save button.
NOTES: Your client may or may not have the ability to provide security settings to the NexusLink 3241u/3241eu. If it does not, then you must set the WPS
AP mode to Configured. Consult the device documentation to check its capabilities.
128
IIa. PUSH-BUTTON CONFIGURATION
The WPS push-button configuration provides a semi-automated configuration method. The WPS button on the front panel of the router can be used for this purpose.
The WPS push-button configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless Access Point (AP) of your WLAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled.
NOTE: The wireless AP on the router searches for 2 minutes. If the router stops searching before you complete Step 4, return to Step 3.
Step 3: Press WPS button
Press and release the WPS button on the front panel of the router. The
WPS LED will blink to show that the router has begun searching for the client.
Step 4: Go to your WPS wireless client and activate the push-button function.
A typical WPS client screenshot is shown below as an example.
Now go to Step 5 (part III. Check Connection) to check the WPS connection.
IIb. WPS – PIN CONFIGURATION
Using this method, security settings are configured with a personal identification number (PIN). The PIN can be found on the device itself or within the software.
The PIN may be generated randomly in the latter case. To obtain a PIN number for your client, check the device documentation for specific instructions.
The WPS PIN configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless
Access Point (AP) of your wireless LAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled.
Step 3: Select the Use STA PIN radio button in the WPS Setup section of the
Wireless Security screen, as shown in A below.
A For Configured mode, input the STA PIN* and click the Add
Enrollee button.
129
* Personal Identification Number (PIN) has to be read from either a sticker or the display on the new wireless device.
B - For Unconfigured mode, select Unconfigured from the Set WPS AP mode drop-down menu and click the Apply/Save button. Input the Device PIN displayed to your wireless client to initiate the PIN connection.
Step 4: Activate the PIN function on the wireless client. For Configured mode, the client must be configured as an Enrollee. For Unconfigured mode, the client must be configured as the Registrar. This is different from the
External Registrar function provided in Windows Vista.
The figure below provides an example of a WPS client PIN function in-progress.
III. CHECK CONNECTION
Step 5: If the WPS setup method was successful, you will be able access the wireless AP from the client. The client software should show the status.
The example below shows that the connection established successfully.
You can also double-click the Wireless Network Connection icon from the
Network Connections window (or the system tray) to confirm the status of the new connection.

Field
Fragmentation
Threshold
RTS Threshold
Description
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 fragmented, i.e., split into, smaller units suitable for the circuit size. Packets smaller than the specified fragmentation threshold value are not fragmented. Enter a value between 256 and 2346. If you experience a high packet error rate, try to slightly increase your Fragmentation Threshold. The value should remain at its default setting of 2346. Setting the Fragmentation
Threshold too low may result in poor performance.
Request to Send, when 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. The NIC transmits smaller packet without using RTS/CTS. The default setting of 2347 (maximum length) disables RTS
Threshold.
DTIM Interval
Beacon 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.
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).

Chapter 7 Voice
This chapter first describes the various options for configuration of the SIP voice service. It then provides detailed instructions for making telephone calls using VoIP
(Voice over IP) or PSTN (Public Switched Telephone Network) services. Session
Initiation Protocol (SIP) is a peer-to-peer protocol used for Internet conferencing, telephony, events notification, presence and instant messaging.
SIP is designed to address the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call.
NOTE : The SIP standard is set by the Internet Engineering Task Force (IETF).
141
The SIP standard defines the following agents/servers:
User Agents ( UA ) - SIP phone clients (hardware or software)
Proxy Server – relays data between UA and external servers
Registrar Server - a server that accepts register requests from UA
Redirect Server – provides an address lookup service to UA
The following subsections present Basic , Advanced and Debug SIP screens.
Each screen provides various options for customizing the SIP configuration.

A dial plan establishes the expected sequence of digits dialed on subscriber premises equipment, such as telephones, in private branch exchange (PBX) systems, or in other telephone switches to effect access to specific telephone networks for telephone calls, and to effect or activate specific telephone system features.
In private branch exchanges in the U.S. a dial plan may specify the dialing for the following destinations:
Internal extension numbers of two, three, or four digits.
Local numbers of seven or ten digits, which may be preceded by a 9, if required to access an outside line.
Long distance numbers of eleven digits, consisting of a 1, a three-digit area code, and a seven-digit number; preceded by a 9 if required.
International numbers of any length starting with 011 and preceded by a 9 if required.
Similarly, telephony service operators may provide dialing sequences for special services, such as directory assistance and emergency services.
PBX equipment, carrier switching systems, or end-user telephones may specify a variable-length dial plan or a fixed-length dial plan.

7.4 SIP CCTK Setting
The CCTK WEB setting allows the user to set up a digitmap for dialing number rule.
156
7.5 Telephone Calls
To make a call, simply dial the number. The dial plan (i.e. the dialed digits) is normally customized for each installation. The default dial plan allows for dialing of
4-digit extensions or direct IP addresses. For shorter extension numbers (e.g.
3-digits) adding a “#” at the end.
When a Call Server (SIP Proxy Server) is configured into the system, the dialed digits are translated and routed by the Call Server to the correct destination as registered with the Call Server.
If no Call Server is configured, calls can still be made using 4-digit extensions, rather than using full IP addresses. The originator translates the dialed-digits to a destination device as follows:
First Digit: Line identifier (for multi-line gateways)
Remaining digits: Host number part of an IP address. The Network number
part is considered to be the same as the caller’s IP address.
For example, if a caller at address 10.136.64.33/24 dials “2023”, the call will be placed to the second line at address 10.136.64.23. All devices have to be on the same Class C subnet (24-bit subnet mask).
To dial an IP address directly, dial the IP address digits using * on the keypad as the dot. Complete the address with a final * or #. When using IP address dialing it is not possible to specify which line at a gateway is called, so the gateway always routes
IP-address dialed calls to the first line.
Network busy tone (fast busy) will be played for unknown or unreachable destinations. To answer a call, pick up the phone or press the hands free button.
Caller ID
The Call Manager delivers Calling Number when placing calls. The calling number is transmitted to the analog line for CLASS recognition.
Call Hold
To put a call on hold, press flash then hang up (optional). To return to the original call, press flash or pick up the phone. The phone will issue a short ring burst every
30 seconds or so while on-hook to remind you that a call is on hold.
Call Transfer
To transfer a call, press flash then dial the new number.
To transfer immediately, hang up (blind transfer).
To transfer with consultation, wait for the party to answer, consult, and hang up.
To abort the transfer (if the third party does not answer); press flash to return to the original call.
Conference Calling
To turn a two-party call into a three-party conference call, press flash and dial the third party. Wait for the party to answer, then press flash. To drop the third party and return to a two-party call, press flash again. To drop yourself out of the conference, hang up. The call will be transferred (so that the other two parties remain connected to each other). In conference mode, the conference initiator performs the audio bridge/mixing function – there are only two voice streams established.
157
Call Waiting
If call waiting is enabled on a line, and you hear the call waiting tone during a call, press flash to answer the second call. The first call is automatically placed on hold.
To switch between calls, press flash again.
To disable the call waiting feature, dial *60
To enable the call waiting feature, dial *61

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 on the NexusLink 3241u/3241eu SDRAM. 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.

Appendix A - Firewall
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 the
Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more filters, specific packet types coming from the LAN can be dropped.
Example 1: Filter Name
Protocol
Source IP address
: Out_Filter1
: TCP
: 192.168.1.45
Source Subnet Mask : 255.255.255.0
Source Port
Dest. IP Address
Dest. Subnet Mask
Dest. Port
: 80
: NA
: NA
: NA
This filter will Drop all TCP packets coming from the LAN with IP
Address/Subnet Mask of 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

This filter will drop all UDP packets coming from the LAN with IP Address /
Subnet Mask of 192.168.1.45/24 and a source port range of 5060 to 6060, destined to 172.16.13.4/24 and a destination port range of 6060 to 7070.
INCOMING IP FILTER
Helps in setting rules to Allow or Deny 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, specific packet types coming from the WAN can be Accepted.
178
Example 1: Filter Name

Selected WAN interface : br0
This rule will ACCEPT all UDP packets coming from WAN interface “br0” 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 FILTER
These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in
Bridge mode. After a Bridge mode connection is created, navigate to Advanced
Setup Security MAC Filtering in the WUI.
Example 1: Global Policy

: eth2
Addition of this rule drops all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC
Address. All other frames on this interface are forwarded.
Example 2: Global Policy
Protocol Type
Dest. MAC Address
: Blocked
: PPPoE
: 00:12:34:56:78:90
Source MAC Address : 00:34:12:78:90:56
Src. Interface : eth1
Dest. Interface : eth2
Addition of this rule forwards all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78 and Source MAC Address of
00:34:12:78:90:56. All other frames on this interface are dropped.

LAUNCH DHCP6C FOR ADDRESS ASSIGNMENT (IANA)
The Internet Assigned Numbers Authority (IANA) is a department of ICANN responsible for coordinating some of the key elements that keep the Internet running smoothly. Whilst the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the
Internet to be globally coordinated, and this coordination role is undertaken by
IANA.
Specifically, IANA allocates and maintains unique codes and numbering systems that are used in the technical standards (“protocols”) that drive the Internet.
IANA’s various activities can be broadly grouped in to three categories:
• Domain Names
IANA manages the DNS Root, the .int and .arpa domains, and an IDN practices
resource.
• Number Resources
IANA coordinates the global pool of IP and AS numbers, providing them to
Regional Internet Registries.
• Protocol Assignments
Internet protocols’ numbering systems are managed by IANA in conjunction
with standards bodies.
LAUNCH DHCP6C FOR PREFIX DELEGATION (IAPD)
An Identity Association for Prefix Delegation (IAPD) is a collection of prefixes assigned to a requesting device. A requesting device may have more than one IAPD; for example, one for each of its interfaces.
A prefix-delegating router (DHCPv6 server) selects prefixes to be assigned to a requesting router (DHCPv6 client) upon receiving a request from the client. The server can select prefixes for a requesting client by using static and dynamic assignment mechanisms. Administrators can manually configure a list of prefixes and associated preferred and valid lifetimes for an IAPD of a specific client that is identified by its DUID.
When the delegating router receives a request from a client, it checks if there is a static binding configured for the IAPD in the client’s message. If a static binding is present, the prefixes in the binding are returned to the client. If no such binding is found, the server attempts to assign prefixes for the client from other sources.
An IPv6 prefix delegating router can also select prefixes for a requesting router based on an external authority such as a RADIUS server using the
Framed-IPv6-Prefix attribute.
LAUNCH DHCP6C FOR RAPID COMMIT
Rapid-Commit; is the process (option) in which a Requesting Router (DHCP Client) obtains "configurable information" (configurable parameters) from a Delegating
Router (DHCP Server) by using a rapid DHCPv6 two-message exchange. The messages that are exchanged between the two routers (RR and DR) are called the
DHCPv6 "SOLICIT" message and the DHCPv6 "REPLY" message.

When the delegating router receives a request from a client, it checks if there is a static binding configured for the IAPD in the client’s message. If a static binding is present, the prefixes in the binding are returned to the client. If no such binding is found, the server attempts to assign prefixes for the client from other sources.
An IPv6 prefix delegating router can also select prefixes for a requesting router based on an external authority such as a RADIUS server using the
Framed-IPv6-Prefix attribute.
LAUNCH DHCP6C FOR RAPID COMMIT
Rapid-Commit; is the process (option) in which a Requesting Router (DHCP Client) obtains "configurable information" (configurable parameters) from a Delegating
Router (DHCP Server) by using a rapid DHCPv6 two-message exchange. The messages that are exchanged between the two routers (RR and DR) are called the
DHCPv6 "SOLICIT" message and the DHCPv6 "REPLY" message.
FIXED MTU
Fixed Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which the layer can pass onwards. This value is 1500 for PPPoA.

ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information into the system log. This is for debugging errors and not for normal usage.
ENABLE MLD MULTICAST PROXY
Multicast Listener Discovery (MLD) is a component of the Internet Protocol Version
6 (IPv6) suite. MLD is used by IPv6 routers for discovering multicast listeners on a directly attached link, much like IGMP is used in IPv4. The protocol is embedded in
ICMPv6 instead of using a separate protocol.
ENABLE MLD MULTICAST SOURCE
Click to allow use of this WAN interface as Multicast Listener Discovery (MLD) multicast source.
STEP 3: Choose an interface to be the default gateway.
Click Next to continue or click Back to return to the previous step.
241
STEP 4: Select DNS Server Interface from available WAN interfaces OR enter static
DNS server IP addresses for the system. In ATM mode, if only a single PVC
with IPoA or static IPoE protocol is configured, Static DNS server IP
addresses must be entered.
Select the configured WAN interface for IPv6 DNS server information OR enter the static IPv6 DNS server Addresses. Note that selecting a WAN interface for IPv6 DNS server will enable DHCPv6 Client on that interface.
Click Next to continue or click Back to return to the previous step.
242
STEP 5: The WAN Setup - Summary screen shows a preview of the WAN service
you have configured. Check these settings and click Apply/Save if they
are correct, or click Back to modify them.
After clicking Apply/Save , the new service should appear on the main screen.
