More about Networks

The FRITZ!Box is delivered with preconfigured network settings. Accord-

ing to these settings, all network devices connected with the FRITZ!Box

are located in a single network.

The network settings can be changed and adapted to your conditions

and needs. But you should do so only if you are well versed in network-

ing technology.

The Glossary explains concepts and terminology having to do with

IP networks.

•

The section “Network Overview” from page 151 introduces the

network overview of the FRITZ!Box.

•

The sections “IP Address” from page 154 and “DHCP Server” from

page 155 explain when it may make sense to change the precon-

figured network settings, what the effects of these changes are,

and how to make the changes.

Section “The Prioritization of Network Applications and Network

Devices” from page 164 explains how you can assign priorities to

network applications and network devices for accessing the Inter-

net connection.

3.1

Network Overview

The FRITZ!Box user interface shows an overview with all of

the devices and users connected with the FRITZ!Box.

The

“

Devices and Users” network overview is found in the

menu:

“Home Network

/ Network”.

Network Overview

There is an entry in the network overview for each user

and each network device. The columns have the following

meanings:

Symbols

The symbol in front of each name indicates

whether the entry is a user or a network de-

vice. In the case of network devices the sym-

bol also indicates whether the device is con-

nected via a network (LAN) cable or wireles-

sly (via WLAN),

Name

This column displays the name under which

the user or the network device is known to

the FRITZ!Box. The names of network devices

can be changed by clicking the button to edit

the entry.

IP Address

For network devices, also displayed is the IP

address with which the device is integrated

into the FRITZ!Box network.

Properties

This column indicates whether port forward-

ing or child protection is enabled for the re-

spective user or network device.

Button for editing the entry

The button opens the detailed view of the

entry. This view displays information about

the network device, for instance on child

protection or port forwarding settings. The

name of the device in the FRITZ!Box can be

changed here.

Button for deleting the entry

Users or network devices that do not have an

active connection to the FRITZ!Box can be

deleted from the network overview by click-

ing this button.

Always assign the same IP address

153

Always assign the same IP address

The detailed view for network devices includes the setting

“Always assign this network device the same IP address”.

When this setting is enabled for a network device, the

DHCP server of the FRITZ!Box will always assign the same

IP address to this device each time the connection is es-

tablished.

Start Computer: Wake on LAN

The detailed view for network devices that are connected

with the FRITZ!Box via a network (LAN) port includes the

“Start Computer” button. Use this button to start comput-

ers that support Wake On LAN.

With the Wake on LAN function you can start computers in

your FRITZ!Box via the Internet. For instance, you can ac-

cess a computer at any time using remote maintenance

software, without wasting electricity by keeping the com-

puter switched on permanently.

3.2

IP Settings

The IP settings of the FRITZ!Box are preset upon delivery

with the following values:

The IP address and the corresponding subnet mask yield

the following values:

Factory Settings

All computers are located in the

same IP network

enabled

IP address

192.168.178.1

Subnet mask

255.255.255.0

enabled

Network address of the subnet

192.168.178.0

computers

192.168.178.2 -

UPnP Settings

The following addresses cannot be assigned becuase they

are reserved for certain purposes:

3.3

UPnP Settings

The Universal Plug-and-Play (UPnP) service included in

your FRITZ!Box provides status information about the

FRITZ!Box to all connected computers. Programs with UP-

nP support on these computers can receive this informa-

tion and use them to display the status of the FRITZ!Box

(e.g., DSL synchronization, connection status, data trans-

mission). UPnP service thus allows you to monitor your

FRITZ!Box from a connected computer.

3.4

IP Address

Upon delivery the FRITZ!Box is assigned the following IP

address:

192.168.178.1

If you would like to change the IP address, please read

through the following sections. Also note the additional

information in the section “Reserved IP Addresses” on

page 155.

When Does It Make Sense to Change the IP Address?

You should change the IP address of the FRITZ!Box if the

following apply to your network:

•

You have an existing local IP network, one subnet

with several computers.

•

Fixed IP addresses are registered in the network set-

tings of the computer, and you do not want to or are

not permitted to change these addresses.

192.168.178.1

is used by the FRITZ!Box itself

192168178254

reserved for internal use

192.168.178.255

broadcast address used to send messag-

es into the network

Reserved IP Addresses

155

•

You want to connect the FRITZ!Box to the local IP net-

work in order to make the FRITZ!Box features avail-

able to all of the computers in the IP network.

Reserved IP Addresses

The entire IP network 192.168.180.0 in the FRITZ!Box is

reserved for internal purposes.

IP addresses from this network may not be assigned to the

FRITZ!Box.

3.5

DHCP Server

The FRITZ!Box is equipped with its own DHCP server. The

DHCP server is enabled by default in the factory settings.

The following range of IP addresses is reserved for the

DHCP server in the factory settings:

192.168.178.20 - 192.168.178.200

This IP address can be changed as needed.

Every time the operating system on a computer connected

with FRITZ!Box is started, the DHCP server assigns it an IP

address from the IP address range of the DHCP server.

Assigning the IP addresses via the DHCP server ensures

that all of the computers connected with the FRITZ!Box are

located in the same IP network.

Only one DHCP server may be active within any network.

The computers can receive their IP addresses from the

DHCP server only if the setting “Obtain an IP address au-

tomatically

”

is enabled in the their IP settings. For more

information, see the section “Obtaining an IP Address Au-

tomatically” from page 115.
