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.
60
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.
61
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.
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.
5.15 Certificate
A certificate is a public key, attached with its owner’s information (company name,
server name, personal real name, contact e-mail, postal address, etc) and digital
signatures. There will be one or more digital signatures attached to the certificate,
indicating that these entities have verified that this certificate is valid.

functionality, which provides basic quality of service for
time-sensitive applications (e.g. VoIP, Video).
Enable
Wireless
Multicast
Forwarding
Select the checkbox to enable this function.
SSID
[1-32
characters]
Sets the wireless network name. 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 user will not be
granted access.
BSSID The BSSID is a 48-bit identity used to identify a particular BSS
(Basic Service Set) within an area. In Infrastructure BSS
networks, the BSSID is the MAC (Media Access Control) address of
the AP (Access Point); and in Independent BSS or ad hoc networks,
the BSSID is generated randomly.
Country A drop-down menu that permits worldwide and specific national
settings. Local regulations limit channel range:
US= worldwide, Japan=1-14, Jordan= 10-13, Israel= 1-13
Max Clients The maximum number of clients that can access the router.

NOTE: Remote wireless hosts cannot scan Guest SSIDs.
68
6.2 Security
The following screen appears when Wireless Security is selected. The options shown
here allow you to configure security features of the wireless LAN interface.
Click Save/Apply to implement new configuration settings.
WIRELESS SECURITY
Wireless security settings can be configured according to Wi-Fi Protected Setup
(WPS) or Manual Setup. The WPS method configures security settings automatically
(see 6.2.1 WPS) while the Manual Setup method 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 box. 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 authenti
cation
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.
69
The settings for WPA authentication are shown below.
The settings for WPA-PSK authentication are shown next.
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.
70
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. 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.
6.2.1 WPS
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 CT-5374 has both a WPS button on the device and a virtual button
accessible from the web user interface (WUI).
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. You must
choose either the Push-Button or PIN configuration method for Steps 6 and 7.
I. Setup
Step 1: Enable WPS by selecting Enabled from the drop down list box shown.
71
Step 2: Set the WSC AP Mode. Configured is used when the CT-5374 will assign
security settings to clients. Unconfigured is used when an external
client assigns security settings to the CT-5374.
NOTES: Your client may or may not have the ability to provide security settings to
the CT-5374. If it does not, then you must set the WSC AP mode to
Configured. Consult the device documentation to check its capabilities.
In addition, using Windows Vista, you can add an external registrar using
the StartAddER button (Appendix E - WSC External Registrarhas
detailed instructions).
II. NETWORK AUTHENTICATION
Step 3: Select Open, WPA-PSK, WPA2-PSK, or Mixed WPA2/WPA-PSK network
authentication mode from the Manual Setup AP section of the Wireless
Security screen. The example below shows WPA2-PSK mode.
Step 4: For the Pre-Shared Key (PSK) modes, enter a WPA Pre-Shared Key. You
will see the following dialog box if the Key is too short or too long.
72
Step 5: Click the Save/Apply button at the bottom of the screen.
IIIa. PUSH-BUTTON CONFIGURATION
The WPS push-button configuration provides a semi-automated configuration
method. The WPS button on the rear panel of the router can be used for this
purpose or the Web User Interface (WUI) can be used exclusively.
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 7, return to Step 6.
Step 6: First method: WPS button
Press the WPS button on the rear panel of the router. The WPS LED will
blink to show that the router has begun searching for the client.
Second method: WUI virtual button
Select the Push-Button 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.
B - For Unconfigured mode, click the Config AP button.
Step 7: Go to your WPS wireless client and activate the push-button function.
A typical WPS client screenshot is shown below as an example.
73
Now go to Step 8 (part IV. Check Connection) to check the WPS connection.
IIIb. 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.
NOTE: Unlike the push-button method, the pin method has no set time limit.
This means that the router will continue searching until it finds a client.
Step 6: 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, enter the client PIN in the box provided and
then click the Add Enrollee button (see below).
B - For Unconfigured mode, click the Config AP button.
Step 7: 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.
Now go to Step 8 (part IV. Check Connection) to check the WPS connection.
74
IV. CHECK CONNECTION
Step 8: 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.

The new amendment allows IEEE 802.11n units to fall back to
slower speeds so that legacy IEEE 802.11x devices can coexist
in the same network. 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.)

Support 802.11n
Client Only
Turn Off to allow 802.11b/g clients access to the router.
Turn On to prohibit 802.11b/g clients access to the router.
54g Rate Drop-down menu that specifies the following fixed rates:
Auto: Default. Uses the 11 Mbps data rate when possible but
drops to lower rates when necessary. 1 Mbps, 2Mbps,
5.5Mbps, or 11Mbps fixed rates. The appropriate setting is
dependent on signal strength.
Multicast Rate Setting for multicast packet transmit rate (1-54 Mbps)
Basic Rate Setting for basic transmission rate.
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
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.
RTS Threshold 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 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).
Global Max Clients
The maximum number of clients that can connect to the router.

85
Option
Description
Log Indicates whether the system is currently recording events. The user
can enable or disable event logging. By default, it is disabled. To
enable it, select the Enable radio button and then click Apply/Save.
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 on the CT-5374 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.
Display

perform auto-configuration, provision, collection, and diagnostics to this device.
Select desired values and click Apply/Save to configure TR-069 client options.
The table below is provided for ease of reference.
Option Description
Inform Disable/Enable TR-069 client on the CPE.
Inform Interval The duration in seconds of the interval for which the CPE
MUST attempt to connect with the ACS and call the Inform
method.
ACS URL URL for the CPE to connect to the ACS using the CPE WAN
Management Protocol. This parameter MUST be in the form
of a valid HTTP or HTTPS URL. An HTTPS URL indicates that
the ACS supports SSL. The “host” portion of this URL is
used by the CPE for validating the certificate from the ACS
when using certificate-based authentication.
ACS User Name Username used to authenticate the CPE when making a
connection to the ACS using the CPE WAN Management
Protocol. This username is used only for HTTP-based
authentication of the CPE.
ACS Password Password used to authenticate the CPE when making a
connection to the ACS using the CPE WAN Management
Protocol. This password is used only for HTTP-based
authentication of the CPE.
WAN Interface used
by TR-069 client
Choose Any_WAN, LAN, Loopback or a configured
connection.
88
Option Description
Display SOAP
messages on serial
console
Enable/Disable SOAP messages on serial console. This
option is used for advanced troubleshooting of the device.
Connection Request
Authorization Tick the checkbox to enable.
User Name Username used to authenticate an ACS making a
Connection Request to the CPE.
Password Password used to authenticate an ACS making a
Connection Request to the CPE.
URL IP address and port the ACS uses to connect to CT-5374.
The Get RPC Methods button forces the CPE to establish an immediate connection
to the ACS. This may be used to discover the set of methods supported by the ACS
or CPE. This list may include both standard TR-069 methods (those defined in this
specification or a subsequent version) and vendor-specific methods. The receiver of
the response MUST ignore any unrecognized methods.
8.5 Internet Time
This option automatically synchronizes the router time with Internet timeservers.
To enable time synchronization, tick the corresponding checkbox , choose your
preferred time server(s), select the correct time zone offset, and click Save/Apply.
NOTE: Internet Time must be activated to use 5.7 Parental Control (page 43).
In addition, this menu item is not displayed when in Bridge mode since
the router would not be able to connect to the NTP timeserver.
89

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 : Out_Filter1
Protocol : TCP
Source IP address : 192.168.1.45
Source Subnet Mask : 255.255.255.0
Source Port : 80
Dest. IP Address : NA
Dest. Subnet Mask : NA
Dest. Port : 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 : Out_Filter2
Protocol : UDP
Source IP Address : 192.168.1.45
Source Subnet Mask : 255.255.255.0
Source Port : 5060:6060
Dest. IP Address : 172.16.13.4
Dest. Subnet Mask : 255.255.255.0
Dest. Port : 6060:7070
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.
92
Example 1: Filter Name : In_Filter1
Protocol : TCP
Policy : Allow
Source IP Address : 210.168.219.45
Source Subnet Mask : 255.255.0.0
Source Port : 80
Dest. IP Address : NA
Dest. Subnet Mask : NA
Dest. Port : NA
Selected WAN interface : br0
This filter will ACCEPT all TCP packets coming from WAN interface “br0” with IP
Address/Subnet Mask 210.168.219.45/16 with 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
Policy : Allow
Source IP Address : 210.168.219.45
Source Subnet Mask : 255.255.0.0
Source Port : 5060:6060
Dest. IP Address : 192.168.1.45
Dest. Sub. Mask : 255.255.255.0
Dest. Port : 6060:7070
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 : Forwarded
Protocol Type : PPPoE
Dest. MAC Address : 00:12:34:56:78:90
Source MAC Address : NA
Src. Interface : eth1
Dest. Interface : 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 : Blocked
Protocol Type : PPPoE
Dest. MAC Address : 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.
93
DAYTIME PARENTAL CONTROL
This feature restricts access of a selected LAN device to an outside Network through
the CT-5374, as per chosen days of the week and the chosen times.
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
With this rule, a LAN device with MAC Address of 00:25:46:78:63:21 will have
no access to the WAN on Mondays, Wednesdays, and Fridays, from 2pm to 6pm.
On all other days and times, this device will have access to the outside
Network.

Appendix D - SSH Client
Unlike Microsoft Windows, Linux OS has a ssh client included. For Windows users,
there is a public domain one called “putty” that can be downloaded from here:
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
To access the ssh client you must first enable SSH access for the LAN or WAN from
the Management Access Control Services menu in the web user interface.
To access the router using the Linux ssh client
For LAN access, type: ssh -l root 192.168.1.1
For WAN access, type: ssh -l support WAN IP address
To access the router using the Windows “putty” ssh client
For LAN access, type: putty -ssh -l root 192.168.1.1
For WAN access, type: putty -ssh -l support WAN IP address
NOTE: The WAN IP address can be found on the Device Info WAN screen
