Precautions

Postpone installation until there is no risk of thunderstorm or lightning activity in the area.
To prevent overhe ating the VT2442, do not block the ventilation holes on the unit.
Do not open the VT2442. Refer all service to Vonage.
Be sure you read and understand “Your Internet T elephone Service and 911” and “Cautions Related to Electrical

Shock and Other Safety Concerns” on page ii.

Caution!

We recommend powering your VT2442 through a surge protector or universal power supply (UPS).

Gather Information

You may need to obtain the following information about your high-speed Internet connection:

• For a DSL connection only, your user name and password

• For a cable modem connection using static IP addresses only, your IP address, subnet mask, default

gateway, and DNS server IP address or addresses

If you already have a router, we recommend printing its configuration screens to use for reference during Basic

Configuration.

Connect the VT2442

• If you already have a router, use instructions A: Installation With an Existing Router (see page 7).

If you have more than one computer connected to a single Internet connection, you have a router.

• If your cable or DSL modem has a built-in router with multiple computers connected, you should also use

instructions A.

Some cable data and DSL providers supply modems containing a router. If your modem has
multiple Ethernet ports, it probably contains a router. If you are not sure, call your cable or DSL
provider and ask them whether your modem contains a router.

• If you have a standard cable or DSL modem with just one computer connected, use instructions B: Installation

With a Standard Modem (see page 9).

You can place the VT2442 on a flat surface horizontally or vertically. For vertical installation, insert the voice
gateway into the supplied base stand. The voice gateway slides snugly into a notch in the stand to keep it stable.

Basic Configuration

The VT2442 provides a graphical user interface (GUI) to configure Ethernet, router, DHCP, and security settings.
It is much easier to configure your local area network (LAN) using a VT2442 than with traditional networking
equipment. For basic operation, most default settings require no modification.

The following sections describe:

• Logging In to the VT2442 (see page 13)

• Configuration Overview (see page 14)

• Restarting the VT2442 (see page 15)

• Logging Out (see page 15)

• WAN Configuration (see page 16)

• LAN Configuration (see page 20)

If DHCP is enabled on all of the computers on your home network (LAN), you do not need to change any of the
default LAN settings. Unless you have sufficient networking knowledge, we recommend not changing any LAN
settings.

Multicast

Multicasting is a form of limited broadcast. UDP is used to send datagrams to all computers in a host group, one or
more hosts identified by the same destination IP address. The following statements apply to host groups:

• Anyone can join or leave a host group.

• There are no restrictions on the host location.

• There are no restrictions on the number of members that may belong to a host group.

• A host may belong to multiple host groups.

• Non-members can send UDP datagrams to the host group.

Multicasting is useful when the same data needs to be sent to more than one device; for example, if one device is
responsible for acquiring data that many other devices need. Using multicasting uses less network bandwidth than
sending the same data to individual devices.

Multicasting also enables you to receive multicast video streams from multicast servers. The voice gateway
supports an Internet Group Management Protocol (IGMP) proxy that handles IGMP messages. When enabled,
the voice gateway acts as a proxy for a LAN host making requests to join and leave multicast groups.

Multicast fields

Field Description

Field Description

Enable RIP Enables RIP. Any RIP-enabled router:

• Sends automatic update packets containing its routing table periodically (every 30 seconds)

• Adds, deletes, or modifies routes in its routing table based on periodic updates from other routers

• Responds to requests for its routing table

Protocol Sets the RIP version:

• RIP v1 (UDP protocol)

• RIP v2 (multicast protocol)

• RIP v1 compatible (UDP protocol with multicast format)
Routers using RIP v1 or a compatible protocol can communicate with each other, but not to routers

using RIP v2.

Enable
Password

Password The password can have up to 16 characters.
Interface Normally, when it is enabled on a router, RIP dynamically provides routes on all configured interfaces.

(Optional) RIP v2 enables simple plain-text password-based authenti cation for RIP packets. It is
disabled if RIP v1 is selected.

On the VT2442, you can select which routes are distributed through the network:

• LAN — Sets the direction in which RIP messages are sent on the LAN interface

• WAN — Sets the direction in which RIP messages are sent on the WAN interface

The options for LAN and WAN are:

• Both — receive and send updates to the routing table to other routers on the interface

• In — receive but do not send routing updates on that interface

• Out — send but do not receive routing updates on the interface

• None — do not send or receive routing updates through the interface

Be sure the telephone connected to the VT2442 is disconnected from the wall jacks

that traditional phone companies use. If not, the VT2442 cannot connect with the
Vonage server and you will not get a dial tone.

Compare your device connections to those shown in “Installation With an Ex ist in g

Router” on page 7 or “Installation With a Standard Modem” on page 9.

The order in which you turn the devices on is very important. Try the procedure for

“Resetting All of Your Equipment” on page 66.

Check that the Ethernet cable is properly connected to the VT2442 and the computer.
If you have a cable modem only, check that your TV is working and the picture is

clear. If you cannot receive TV channels, your cable data service will not function.
Contact your cable provider.

If you have a DSL modem only, check that your DSL service is working. Contact your
DSL provider.

Resetting All of Your Equipment

You can resolve many installation issues by resetting all of your equipment.
To reset all of your equipment:

1 Turn off your computer, VT2442 voice gateway, router (if you have one), and DSL or cable modem.
2 Turn the devices back on, one at a time, in this order:

• Modem

• Router (if present)

• VT2442

• Computer

Replacing an Existing Router with the VT2442

You can connect up to four computers directly to the VT2442 Ethernet ports. It may be easiest to have only a
single router — the one built in to your VT2442 — on your home network.

1 Shut down your computers properly. Follow the instructions provided with the computers.
2 Unplug your cable or DSL modem power cord or adapter.
3 Unplug your router.
4 Disconnect any cables connecting your router to the modem. Please leave your modem connected to

the cable or phone line that provides your Internet connection.

Hint: Y our modem should remain off for about 10 minutes to “clear its memory” so it can recognize the
VT2442 when you turn it back on. You can continue with the installation during this time.

Frequently Asked Questions

If you do not understand a term or abbreviation, check the Glossary.

Q What does the Motorola VT2442 Voice Gateway do?

A The VT2442 Voice Gateway is a stand-alone media terminal adapter (S-MTA) containing a home router:

• As an S-MTA, it converts analog voice signals to and from a standard telephone to digital data that can

be transmitted through a broadband connection across the Internet. It provid es an alternate means to
make voice calls.

• Its built-in router provides full network connectivity, a firewall, and VPN passthrough.

• VT2442 prioritizes voice calls to enable simultaneous voice and data communication with no loss of

voice call quality. For a description of the VT2442 features, see “Overview” on page 1.

Q Will the VT2442 Voice Gateway work with a cable modem or DSL modem?

A Yes. The VT2442 Voice Gateway supports DHCP, which is specified for DOCSIS

PPPoE, which is used by most DSL providers.

Q Can I operate a virtual private network (VPN) application behind the VT2442?

A

Yes. The VT2442 Voice Gateway supports IPSec and PPTP, the most common VPN protocols.

®

cable modems, and

Q Can I play online games through my VT2442?

A

By default, the voice gateway blocks all unsolicited messages to the computer or local network as a standard
security measure. However, for online games that require some unsolicited messages to be transmitted
through the voice gateway, you can specify ports and IP addresses on which to allow unsolicited messages.
The VT2442 enables you to set up virtual servers or a DMZ.

Q How do I configure the VT2442?

A

Most people can send and receive calls immediately after completing Installation! You can configure your
home or office network through a GUI using a connected computer configured to obtain its IP address using
DHCP. Or, you can configure the computer statically to 192.168.15.xxx (xxx is from 2 to 254), subnet mask

255.255.255.0, and default gateway 192.168.15.1.

Q What is included with the built-in router?

A The VT2442 supports a firewall, RIP, port triggers, advanced ALGs such as RSVP, POP3, SNMP, and

streaming media. No separate routers are needed.

Q Is any Quality of Service (QoS) implemented on the VT2442 Voice Gateway?

A Although VoIP service is typically best-effort, the VT2442 provides upstream voice prioritization to ensure that

upstream voice data has priority over other Web data. This ensures good voice quality even during heavy
upstream data transfers, such as e-mail synchronization or file sharing.

an IP network. DHCP eliminates the need to manually assign static IP addresses by “leasing” an
IP address and subnet mask to each client. It enables the automatic reuse of unused IP addresses.

The VT2442 can simultaneously be a DHCP client and a DHCP server:

• A DHCP server at Vonage headend assigns a WAN IP address to your VT2442.

• The VT2442 contains a built-in DHCP server that assigns private IP addresses to each computer

on its LAN.

Internet. A DMZ prevents direct access by outside users to private data. (The term comes from the
geographic buffers located between some conflicting count ries such as North and South Korea. ) In a
typical small DMZ configuration, the DMZ host receives requests from private LAN users to access
external web sites and initiates sessions for th ese requests. The DMZ host cannot initiate a session
back to the private LAN. Internet users outside the private LAN can access only the DMZ host. You
can use a DMZ to set up a web server or for gaming without exposing confidential data.
