Defines the DHCPv6 lease time duration in minutes between 1 and 71582788. A

DHCPv6 user’s PC gets an IPv6 address with a lease time. When the lease time expires, the PC must connect to the DHCPv6 server and be issued a new, unused

IPv6 address.

Note: The default DHCPv6 lease time is 3600. For optimum performance, it should be changes to 86400 seconds (24 hours). This helps resolve connectivity issues with some MAC and Windows 7 devices that turn off the network interface when they go into standby mode. This results in slow Web browsing until the device gets a new IPv6 address via DHCPv6.

Enables Rapid Commit. When enabled, the server recognizes this option in Solicit messages sent from the DHCPv6 client. The server and client then use a twomessage exchange (Solicit and Reply) to configure clients, rather than the default four-message exchange (Solicit, Advertise, Request, and Reply). This provides faster client configuration when networks are under heavy traffic loads.

Polycom, etc.).

When enabled, allows encrypted IPsec VPN traffic to pass through the router between the IPsec VPN Client application on the PVC/Mac and the IPsec VPN Concentrator (e.g.

Barracuda, Cisco, Juniper, etc.) for access to the “company VPN.”

When enabled, allows encrypted PPTP VPN traffic to pass through the router between the PPTP VPN Client application on the PVC/Mac and the PPTP VPN Server (e.g.

Windows Server 2013) for access to the “company VPN.”

Optimizes the bandwidth utilization compared with unicast (especially video streaming applications).

Activates Universal Plug and Play (UPnP) when enabled. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities, and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use. Gaming consoles and Web cameras are examples of devices that can use UPnP.

When enabled, this allows bridging of traffic to and from the Internet for ALL LAN side primary interfaces (Ethernet, MoCA, and Wireless Primary Network).

Note: When the Primary Network Bridged option is enabled, menu items for other functions can still be seen, but are not active.

DNS Relay

Allows the DVW32CB to act as the “relay” device. Each PC that wants to access a URL does not have to send a DNS request to a DNS server on the Internet. DNS is used to resolve a URL (Web site name) to an IP address. DNS Relay is typically used for commercial applications where each device/PC connected to the device uses the DNS

Relay address rather than going to a public DNS server hosted by an ISP to look up a

URL.

6.5.1

Before Setting Up Forwarding

Try the following options before you assign forwarding rules:

1. Enable Universal Plug and Play (UPnP). This may resolve the issue you have without setting up forwarding rules.

a. Access the Web interface of the DVW32CB, see Accessing the Web User Interface

Locally on page 14 .

b. Click Advanced from the main menu.

c. Click Options from the left menu.

d. Check the UPnP Enable box

.

e. Click Apply.

f. Test your local host or application such as your Xbox to see if it is functioning properly. Continue with port forwarding if the host or application is not communicating correctly.

2. Assign a Static IP lease to the client/host to which you are setting up forwarding. This way, the IP does not change and disrupt your forwarding rules. For example, if you are hosting a Web server in your internal network, and you wish to setup a forwarding rule for it, assign a static IP lease to that system to keep the IP from renewing and disrupting the forwarding rule.

6.5.2

Setting Up Forwarding

If the suggestions in

Before Setting Up Forwarding on page 53

did not correct your communication problem, use port forwarding.

You need the following information to set up port forwarding:

IP address of each local host system (for example, Xbox) for which you need to setup a port forwarding rule.


53


Port numbers the local host’s application listens to for incoming requests/data (for example, a game or other service). These port numbers should be available in the documentation associated with the application.

NOTE: For detailed information on port forwarding, including how to set it up for specific applications using specific network devices (for example, cable modems), refer to: http://portforward.com or consult your host device or application user manual.

To set up port forwarding:

1. Access the Web interface of the DVW32CB, see Accessing the Web User Interface

Locally on page 14 .


3. Click Forwarding from the left menu.

4. Click either Create IPv4 or Create IPv6.

Setting Up Port Forwarding for an Xbox Example

The following is an example of how you would set up a single Xbox running Modern

Warfare 2. Since multiple ports are used for the Xbox and the Modern Warfare 2 game, a separate forwarding rule is set for each port. Multiple ports and forwarding rules may not be required for other applications.

To set up port forwarding for an Xbox:


2. Click Forwarding from the left side menu.

3. Enter the Xbox IP address in the Local IP field.

4. Define ports used by the Xbox in the Local Start Port and Local End Port fields.

Define the same ports used by the Xbox in the External Start Port and External End

Port fields.

5. Create Port Forwarding rules per port. A rule set up for port 53 works for port 53. A port can be used only by one program at a time.


56

Ubee Interactive Using the Port Triggers Option

NOTE: You can set up applications/services to listen on one internal port. External

Internet users who want to access that application, address it using an external port, such as an Audio server. Internal Ports are the ports to which local servers listen. External

Ports are the ports that the cable modem listens to from the WAN.

6.6

Using the Port Triggers Option

Port Triggers define dynamic triggers for specific devices on the LAN. This allows special applications that require specific port numbers with bi-directional traffic to function properly. Applications such as video conferencing, voice, gaming, and some messaging program features may require these special settings.

Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. The difference between port forwarding and triggering is:

Port forwarding sets a rule to send a service to a single LAN IP address.

Port triggering defines two kinds of ports: trigger port and target port. The trigger port sends a service request from a LAN host to a specific destination port number.

The port the LAN host is required to listen to by the application is called the target port. The server returns responses to these ports.

For example:

1. John requests a file from the Real Audio server (port 7070). Port 7070 is a “trigger” port and causes the device to record John’s computer IP address. The DVW32CB associates John's computer IP address with the “target” port range of 6970-7170.

2. The Real Audio server responds to a port number ranging between 6970-7170.

3. The DVW32CB forwards the traffic to John’s computer IP address.


57

Ubee Interactive Using the Port Triggers Option

4. Only John can connect to the Real Audio server until the connection is closed or expires.

Mixed (11a/n/ac).

Enables or disables the Wi-Fi Protected Access (WPA) security protocol. WPA is a subset of the IEEE 802.11i standard. Key differences between WPA and WEP are user authentication and improved data encryption. Setting WPA alone with a pre-shared key requires a RADIUS or TACACS server for authentication. This method is mostly used in large enterprise implementations.

Enables or disables WPA Pre-Shared Key (WPA-PSK). If you do not have an external

RADIUS server, use WPA-PSK, which requires a single (identical) password entered into wireless gateway and wireless client. As long as the passwords match, a client is granted access to the wireless LAN.

NOTE: In order to enable WPA-PSK, you must first enable WPA2-PSK. When WPA-PSK is enabled, the default WPA/WPA2 encryption is TKIP+AES.

Enables or disables WPA2. This advanced protocol is certified through Wi-Fi Alliance's

WPA2 program and implements the mandatory elements of 802.11i. In particular, it has an

AES-based algorithm (CCMP) that is considered fully secure. Setting WPA2 alone with a pre-shared key requires a RADIUS or TACACS server for authentication. This method is mostly used in large enterprise implementations.

Enables or disables WPA2-PSK. If you do not have an external RADIUS server, use

WPA2-PSK, which requires a single (identical) password entered into wireless gateway and wireless client. As long as the passwords match, a client is granted access to the wireless

LAN. This is the default residential setting. It is more secure than WPA-PSK. When only

WPA2-PSK is enabled, the default WPA2/WPA encryption is AES.

When only WPA2-PSK is enabled, the default encryption is AES.

When both WPA2-PSK and WPA-PSK are enabled, the default encryption is

TKIP+AES.

NOTE: TKIP encryption results in maximum link speed of 54Mbps. Use WPA2-PSK with

AES for maximum performance and encryption security.

Displays the WPA Pre-Shared Key when “Show Key” is checked. The WPA pre-shared key is a unique key for each device. It is a randomly generated character string, 16 characters in length, and can also be found on the device label.

Group Key Update Timer is also supported in WPA-PSK mode.

Enables or disables WEP encryption. If you do not have wireless clients that can use WPA or

WPA2, you can use WEP key encrypting. A higher bit key offers better security. WEP encryption scrambles the data transmitted between the wireless stations and the DVW32CB to keep network communications private. It encrypts unicast and multicast communications in a network. Both the wireless stations and the DVW32CB must use the same WEP key. Data

Encryption can be set to WEP 128-bit, 64-bit, or Disable.

9.5

Using the Wi-Fi Multimedia Option

Use the Wi-Fi Multimedia option to enable quality of service (QoS) to ensure the best service in your wireless networks.

Controls WLAN transmission priority on packets transmitted over the wireless network.

Wi-Fi Multi-Media Quality of Service (WMM QoS) is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.

WMM QoS prioritizes wireless traffic according to the delivery requirements of the individual user and applications. On wireless access points without WMM QoS, all traffic streams are given the same access priority to the wireless network. If a new traffic stream creates a data transmission demand that exceeds the current network capacity, the new traffic stream reduces the throughput of the other traffic streams.

WMM QoS capability allows you to assign access categories (ACs) to various packet streams. The assigned AC of a packet stream depends on the packet’s priority, such as a priority assigned by an application (also referred to as a user priority (UP). An AC may include a common set of enhanced distributed channel access (EDCA) parameters used by QoS to contend for a channel to transmit packets with certain priorities.


82

Ubee Interactive Using the Wi-Fi Multimedia Option

Different ACs can be associated with different power saving parameters. For example, one power saving parameter might be the delivery mechanism used by an access point (AP) to deliver packets to a station (STA) that is operating in a reduced power mode.

WMM transmit opportunity (TXOP) is assigned to each access point. The bounded time interval during which a station can send as many frames as possible as long as the transmission time does not extend past the maximum duration of the TXOP. If a frame is too large to be transmitted in a single TXOP, it should be fragmented into smaller frames. Using TXOP reduces the problem of low rate stations gaining too much channel time in the legacy 802.11 DCF MAC. A TXOP time interval of 0 means it is limited to a single MAC service data unit (MSDU) or MAC management protocol data unit (MMPDU).

NOTE: Disabling WMM will break the 802.11n specification and result in speeds that tend toward a maximum speed of 54Mbps (802.11g max speeds).

To enable the multimedia wireless option:


2. Click WMM (Wi-Fi Multimedia) from the left side menu. Field descriptions are listed below the screen example. This example shows the screen when the DVW32CB is in the 2.4GHz band.

The application chooses the time to wake up and receive data packets to maximize power conservation without sacrificing quality of service. Power Save Support is enabled by default.

Saves changes to the WMM settings.

9.6

Using the Bridging Option

Use the Bridging option to configure the DVW32CB to act as a wireless network bridge and establish wireless links with other wireless access points. To establish a bridge, you need to know the MAC address of the peer device, that must be in wireless bridging mode as well. The DVW32CB can establish up to four wireless links with other wireless access points. When wireless devices are in wireless bridging mode, they form a wireless distribution system that allows computers in one LAN to connect to the computers in the other LAN.

CAUTION: Avoid bridge loops when you enable bridging devices. Bridge loops cause broadcast traffic to circle the network endlessly. This can degrade throughput and disrupt communications.

Distance between wireless clients and the wireless cable modem

Wireless capabilities of the client devices

To determine the received signal strength, refer to

Using the Access Control Option on page 80

and review the RSSI value. A receive signal strength indicator between 0 to -64 dBm is considered optimal. Levels of -67dBm and lower (for example, -70, -80, etc.) have a downward impact on wireless data throughput.

9.7.2

Estimating Wireless Cable Modem to Wireless Client Distances

The information in this section helps you to determine how far a wireless cable modem can be placed from wireless client devices. Environmental variances include the capabilities of wireless clients and the types of material through which the wireless signal must pass. When the wireless cable modem and wireless clients reach the distance threshold between each other, network performance degrades.

To determine wireless cable modem placement:

1. Connect a wireless client to the wireless DVW32CB. Refer to Connecting Devices to the Network on page 11 if needed.

2. Place the wireless client at around one meter (three feet) away from the DVW32CB.

3. Obtain the RSSI value for the connected client. Refer to

Using the Access Control

Option on page 80 . This value is used in the formula further below.

6. Use the attenuation value from the materials table above in the following formula:

Formula:

(Transmit Power, use -30dBm) – (Receiver Sensitivity, use RSSI value) =

Allowable Free Space Loss

Allowable Free Space Loss ÷ Materials Attenuation Value =

Optimal Distance in Feet Between the DVW32CB and a Wireless Client

Example:

(-30dBm) - (-67dBm) = 37dBm (allowable free space loss for a 54Mbps connection)

37dBm ÷.24db/foot (for open space) = 154.16 feet

7. Once you know the optimal feet distance between individual wireless clients and the

DVW32CB, you may resolve and prevent some performance issues.

8. Check the wireless signal strength and speed of the computer connected wirelessly to the DVW32CB. Instructions for checking speeds are provided for both a Windows and

Higher, as many wireless devices such as cordless phones, microwave ovens, and computers use the 2.4GHz frequency.

Lower chance of picking up interference because fewer types of wireless devices use the 5GHz frequency.

Application

Recommended for simple Internet browsing and email, as these applications don’t take too much bandwidth and work fine at a greater distance.

Recommended for applications that require uninterrupted throughput, like media streaming. The wider spectrum delivers better performance.

Note:

If you want to use the 5GHz frequency, all wireless client adapters must support 5GHz.

9.7.4

Selecting a Wireless Channel

You may need to change the wireless channel on which the DVW32CB operates when you are in computing, test, and other environments where several wireless access points may be operating in the 2.4GHz range.

In some cases, you may want to segment your wireless traffic where a group of devices operates on one channel and another group operates on another channel, and so on. This is done by configuring the channel on each wireless access point individually (if you have multiples). If you have control over only one wireless device in an environment where there may be several, you can change the wireless channel on your device to one that is not heavily used.

NOTE: To change the wireless broadcast channel, refer to

Using the Wireless Radio

Option on page 73

.

2.4GHz Channels

The following diagram displays the channels available in the Americas. Each available channel is 22MHz wide. Since channels overlap, it is best to choose channels that have the least overlap (typically 1, 6, and 11 in the Americas, and 1, 5, 9, and 13 in Europe).

Overlapping channels can cause wireless network performance issues.

The internal wireless adapter from Broadcom.

ALG (Application-Level Gateway)

A type of security device that acts on behalf of the application servers on a network, hiding the servers themselves from traffic that might be malicious.

AP (Access Point)

A device that allows wireless devices to connect to a wired network using WiFi, or related standards.

Broadcast

A packet sent to all devices on a network.

BSS (Basic Service Sets)

A basic service set is the fundamental building block of an 802.11 wireless local area network. The overlapping BSS problem refers to a situation where two or more systems, unrelated to each other are in close enough proximity to hear each other physically.

Overlapping BSS may degrade the network performance severely.

BSSID (Basic Service Set Identifier)

The BSSID uniquely identifies a specific access point and is in the same format as a MAC address.

Channel Bonding

A computer networking configuration where two or more network interfaces are combined on a host computer for redundancy or increased throughput. Data is transmitted over these channels as if they are one channel.

CMTS (Cable Modem Termination System)

Typically located in the cable company’s headend, the CMTS is equipment that provides high-speed data services to subscribers, such as cable Internet and Voice over IP (VoIP).

CPE (Customer Premises Equipment)

Default Gateway

The routing device used to forward all traffic that is not addressed to a computer on the local subnet.


103

Ubee Interactive Glossary

DHCP (Dynamic Host Configuration Protocol)

A protocol that centrally automates the assignment of IP addresses in a network. Using the Internet’s set of protocols (TCP/IP), each machine that can connect to the Internet needs a unique IP address. For example, when the service provider sets up computer users with a connection to the Internet, an IP address is assigned to each machine.

DHCP lets the service provider distribute IP addresses and automatically sends a new IP address when a computer is plugged in to the high-speed Internet network. DHCP uses the concept of a “lease” or amount of time an IP address is valid for a computer. Lease times can vary.

DMZ (Demilitarized Zone)

Allows one IP address (or computer) to be placed in between the firewall and the Internet

(usually for gaming and video conferencing). This allows risky, open access to the

Internet.

DOCSIS (Data Over Cable Service Interface Specification)

An International telecommunications standard that permits the addition of high-speed data transfer over an existing cable TV system.

Domain

A subnetwork comprised of a group of clients and servers under the control of one security database.

Domain Name

A descriptive name for an address or group of addresses on the Internet. Domain names are in the form of a registered entity name plus one of a number of predefined top-level suffixes, such as .com, .edu, .org.

DoS (Denial of Service) Attack

An attempt to make a machine or network resources unavailable to its intended users.

DNS (Domain Name System)

An Internet service that locates and translates domain names into IP addresses. Because domain names are alphabetic, they are easier to remember. However, the Internet is based on IP addresses. Every time you use a domain name, a DNS service translates the name into the corresponding IP address. The DNS system is actually its own network. If one DNS server does not know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

Downstream

A term to describe the direction of data from the network service provider to the customer.

DTIM (Delivery Traffic Indication Message)

Informs clients about the presence of buffered broadcast data on the access point.

Ethernet

A standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. It forms the underlying transport vehicle used by several upper-level protocols, including TCP/IP, HTTP, and FTP.

A protocol used to ensure security for VPN negotiation and remote host or network access.

IP (Internet Protocol)

The method or protocol by which data is sent from one computer to another on the

Internet. It is a standard set of rules, procedures, or conventions relating to the format and timing of data transmission between two computers that they must accept and use to understand each other. Used in conjunction with the Transfer Control Protocol (TCP) to form TCP/IP.

IP Address

In the most widely installed level of the IP today, an IP address is a 32-bit binary digit number that identifies each sender or receiver of information that is sent in packet form across the Internet. When you request a Web page or send an e-mail, the IP part of

TCP/IP includes your IP address. IP sends your IP address to the IP address obtained by looking up the domain name in the URL you requested or in the e-mail address to which you are sending a note. A dynamic IP address is an IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server.

IPsec (Internet Protocol Security)

A protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session.

IRC (Internet Relay Chat)

A system that facilitates the transfer of messages in the form of text.

ISP (Internet Service Provider)

A company that provides individuals and companies access to the Internet and other related services.


105

A unit of measurement for data transmission that represents one million bits per second.

MTU (Maximum Transmission Unit)

The size in bytes of the largest packet that can be sent or received.

NAT (Network Address Translation)

A technique by which several hosts or computers share a single IP address for access to the Internet. NAT enables a LAN to use one set of IP addresses for internal traffic and a second set of addresses for external traffic, and provides a type of firewall by hiding internal IP addresses.

NetBios (Network Basic Input/Output System)

A program that allows applications on different computers to communicate within a local area network.

Net2Phone

A software/services company whose principal line of business is SIP-based and

PacketCable-based voice over IP.

Packet

A block of information sent over a network. A packet typically contains a source and destination network address, some protocol and length information, a block of data, and a checksum.

PPTP (Point-to-Point Tunneling Protocol)

A method for ensuring secure communication between virtual private networks.


106


Ranging

A process in which a cable modem sends a range request at a power of 8 dBmV (very low power). If it does not receive a range response from the CMTS, the cable modem retransmits the range request at a 3 dB higher power level and continues the process until a range response is received.

Router

A measurement of the power present in a received radio signal. Lower negative numbers

(for example, -1 to -65) indicate the access point is closer. Greater negative numbers (for example, -66 to -95) indicate the access point is farther away. RSSI is optimal between

0dBm and -64dBm.

RSVP (Resource Reservation Protocol)

A set of communication rules that allows channels or paths on the Internet to be reserved for the multicast transmission of video and other high-bandwidth messages.

RTSP (Real Time Streaming Protocol)

A protocol used in the transfer of real-time streaming media such as audio and video.

107


Subnet

A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 10.1.10 would be part of the same subnet. IP networks are divided using a subnet mask.

Subnet Mask

Combined with the IP address, the IP subnet mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router. A number that explains which part of an IP address comprises the network address and which part is the host address on that network.

Telnet

TCP (Transmission Control Protocol)

A method (protocol) used with the IP to send data in the form of message units

(datagrams) between network devices over a LAN or WAN. While IP handles the actual delivery of the data (routing), TCP keeps track of the individual units of data (packets) that a message is divided into for efficient delivery over the network. TCP requires the receiver of a packet to return an acknowledgment of receipt to the sender of the packet.

TCP/IP (Transmission Control Protocol/Internet Protocol)

The basic communication language or set of protocols to communicate over a network

(developed specifically for the Internet). TCP/IP defines a suite or group of protocols.

TDMA (Time Division Multiple Access)

A method in which cable modems must time-share the upstream channel because there are many cable modems and only one upstream channel frequency.
