Be aware that any configuration changes could compromise your connectivity.

This section (see Figure 1) is intended to present a summary of the Router's

connections, such as WAN and LAN (i.e. Ethernet, USB, Wireless) interfaces.

supports various network connections, both physical and logi-

cal. The Network Connections screen enables you to configure the various pa-

rameters of your physical connections, the LAN and WAN, and create new con-

nections, using tunneling protocols over existing connections, such as PPP and

VPN.

Press the

'Advanced'

button to expand the screen and display all connection

entries.

LAN BRIDGE

The LAN bridge connection is used to combine several LAN devices under one

virtual network. For example, creating one network for LAN Ethernet and LAN

wireless devices.

Please note, that when a bridge is removed, its formerly underlying devices in-

herit the bridge's DHCP settings. For example, the removal of a bridge that is

configured as DHCP client, automatically configures the LAN devices formerly

constituting the bridge as DHCP clients, with the exact DHCP client configura-

tion.

LAN BRIDGE >> GENERAL

To view and edit the LAN bridge connection settings, click the 'LAN Bridge' link

in the 'Network Connections' screen. The 'LAN Bridge Properties' screen will

appear, displaying a detailed summary of the connection's parameters, under

the 'General' tab. These parameters can be edited in the rest of the screen's

tabs, as described in the following sections.

General.

This section displays the connection's general parameters. It is re-

commended not to change the default values unless familiar with the network-

ing concepts they represent. Since your gateway is configured to operate with

the default values, no parameter modification is necessary.

Schedule.

By default, the connection will always be active. However, you can

configure scheduler rules in order to define time segments during which the

connection may be active. Once a scheduler rule(s) is defined, this field

changes to a combo-box, allowing you to choose between the available rules.

Network.

Select whether the parameters you are configuring relate to a WAN,

LAN or DMZ connection, by selecting the connection type from the combo-box.

Physical Address.

The physical address of the network card used for your

network. Some cards allow you to change this address.

MTU.

MTU is the Maximum Transmission Unit. It specifies the largest packet

size permitted for Internet transmission. In the default setting, Automatic, the

gateway selects the best MTU for your Internet connection. Select "Automatic

by DHCP" to have the DHCP determine the MTU. In case you select "Manual",

it is recommended to enter a value in the 1200 to 1500 range.

Internet Protocol.

Select one of the following Internet protocol options from the

'Internet Protocol' combo-box:

-

No IP Address

: Select 'No IP Address' if you require that your gateway have

no IP address. This can be useful if you are working in an environment where

you are not connected to other networks, such as the Internet.

-

Obtain an IP Address Automatically

: Your connection is configured by default

to act as a DHCP client. You should keep this configuration in case your service

provider supports DHCP, or if you are connecting using a dynamic IP address.

The server that assigns the gateway with an IP address, also assigns a subnet

mask. You can override the dynamically assigned subnet mask by selecting the

'Override Subnet Mask' and specifying your own mask instead. You can press

the 'Release' button to release the current leased IP address. Once the address

has been released, the button text changes to 'Renew'. Use the 'Renew' button

to renew the leased IP address.

-

Use the Following IP Address

: Your connection can be configured using a

permanent (static) IP address. Your service provider should provide you with

such an IP address and subnet mask.

DNS Server.

Domain Name System (DNS) Server is the method by which Web

site domain names are translated into IP addresses. You can configure the

connection to automatically obtain a DNS server address, or specify such an

address manually, according to the information provided by your ISP. If you

have previously chosen “Obtain an IP Address Automatically”, a combo-box will

appear.

To configure the connection to automatically obtain a DNS server address, se-

lect 'Obtain DNS Server Address Automatically' from the 'DNS Server' drop

down menu.

To manually configure DNS server addresses, select 'Use the Following DNS

Server Addresses' from the 'DNS Server' drop down menu. Specify up to two

different DNS server address, one primary, another secondary.

IP Address Distribution.

The 'IP Address Distribution' section allows you to

configure the gateway's Dynamic Host Configuration Protocol (DHCP) server

parameters. The DHCP automatically assigns IP addresses to network PCs. If

you enable this feature, make sure that you also configure your network PCs as

DHCP clients. Select one of the following options from the 'IP Address Distribu-

tion' combo-box:

DHCP Server.

Start IP Address

: The first IP address that may be assigned to a LAN host.

Since the gateway's default IP address is 192.168.1.1, this address must be

192.168.1.2 or greater.
