•

Firewall — Enables the VT2542 firewall

Override MAC

If your cable or DSL provider associates a particular service to a specific device, such as your

computer, select this field and type that MAC address in the

MAC

field to use as a “virtual”

WAN MAC address

instead of the VT2542 MAC address. By default, the MAC address printed

on the VT2542 is displayed in this field.

Restore

Restores the actual VT2542 MAC address.

Renew

Requests a new WAN IP address for your VT2542 from the

DHCP

server at Vonage.

Release

Releases the VT2542 WAN IP address.

LAN Configuration

If DHCP is enabled on all of the computers on your home network (LAN), you should not need to change any of

the default LAN settings. For information about enabling DHCP, see

“Configuring TCP/IP”

on page 51.

Unless you have sufficient networking knowledge, we recommend not changing any LAN settings.

Field or Button

Description

Subnet IP Address

Sets your

LAN subnetwork

IP address in

dotted-decimal format

.

We recommend not

changing the default

192.168.15.0.

Netmask

Sets the VT2542

subnet mask

, in dotted-decimal format. The default is 255.255.255.0, which

enables the VT2542 router to support up 253 users connected through multiple hubs,

switches, routers, or wireless access points.

Host

Name

Sets the voice gateway host name. It can contain any alphanumeric characters, except

spaces.

Domain

Sets the domain name. It is used in conjunction with the host name to uniquely identify the

voice gateway. To access the web pages of the voice gateway, you can type 192.168.15.1

(the IP address) or mygateway1.Motorola_VT (hostmame.domain).

Enable DHCP Server

If selected, the

DHCP

server on the voice gateway assigns IP addresses to the computers

and other

hosts

on your network, if they have DHCP enabled (see

“Configuring TCP/IP”

on

page 51). By default, the voice gateway DHCP server is enabled.

If there is another DHCP server running on your network (on another router), you must

disable one of the DHCP servers.

Start IP

Sets the first IP address assigned by the DHCP server, in

dotted-decimal format

. It must be

greater than the IP address value of the voice gateway. For example, if the IP address of the

voice gateway is 192.168.15.1 (default), the starting IP address must be 192.168.15.2 (or

higher).

End IP

Sets the final IP address assigned by the DHCP server, in dotted-decimal format. It cannot

exceed the subnet limit of 254. For example, the default is 192.168.15.254. If the DHCP

server runs out of DHCP addresses, users cannot access network resources. If this happens,

increase the End IP (to the limit of 254) or reduce the Lease Time.

If you change Start IP or End IP, be sure they are in the range specified by the Subnet IP

Address and Netmask. For example, if the voice gateway IP address is 192.168.15.1 (the

default) and you set Start IP and End IP to 192.168.0.2 and 192.168.0.100 respectively,

computers with DHCP enabled cannot communicate with the voice gateway.

Lease Time

Sets the time, in seconds, that a network computer remains connected to the voice gateway

using its current assigned IP address. At the end of this time, the DHCP server renews the

lease or assigns the computer a new IP address. The default is 3600 seconds (1 hour). The

maximum is 999999 seconds (about 278 hours).

Enable DHCP Relay

If selected, the voice gateway forwards requests and responses between the computers on

your network (the DHCP clients) and the DHCP server you chose to use for your network.

Relay IP

If you select Enable DHCP Relay, type the IP address of the DHCP server in dotted-decimal

format.

Server and Relay Off

If selected, you must carefully configure the IP address, Subnet Mask, and DNS settings of

every

host

on your network. Do not assign the same IP address to more than one host. Your

voice gateway must be on the same subnet as the other hosts.

Advanced Configuration

The ADVANCED menu provides the following links:

•

UPnP —

Enables UPnP so traffic for applications using UPnP can pass through the voice gateway

•

IP QoS

— IP quality of service (QoS) enables you to assign priority to Internet traffic based on the source and

destination IP addresses, source and destination ports, packet length, and protocol

•

Port Forwarding

— direct incoming traffic to specific computers on your network

•

IP Filters

— block applications and services based on the IP address of a LAN device

•

LAN Clients

— determine how computers on your network receive an IP address

•

Web Filters

— specify whether proxies, cookies, Java applets, ActiveX controls, or pop-ups can pass through

your voice gateway

•

Dynamic DNS Client

— register your voice gateway with a DNS server to access the voice gateway each

time from the WAN using the host name

•

Multicast

— enable IGMP Multicast

•

Static Routing

— define up to 16 static routes in the voice gateway routing table

•

Dynamic Routing

— define dynamic routes using routing information protocol (RIP)

•

Remote Web Access

— enable access to the voice gateway remotely over the Web

•

Remote SSH Access

— access the voice gateway remotely via secure shell

•

Ethernet Switch

— specify ethernet switch settings

NOTES:

—

A red bullet point indicates that the feature is not enabled; a green bullet point indicates that the feature is

enabled.

—

Universal Plug and Play (UPnP) requires one active WAN connection and the host should support this

feature.

Trusted Mode

If enabled (the default), all IP QoS traffic rules are applied first, regardless of the TOS bit

settings. After the rules are exhausted, the existing TOS bit settings are honored.

If disabled, all rules are also applied, except if there is no match, a default rule of queuing

priority Low is used.
