5.
In the Properties dialog box for the
connection, in the Advanced tab


Enable ICF by selecting the Protect My Computer
And Network By Limiting Or Preventing Access To
This Computer From The Internet check box
Disable ICF by clearing the Protect My Computer


The Security Logging tab




Lets you specify whether you want to log dropped
packets and successful connections
Lets you set the size limit and location of the log
file
By default, the log file is PFIREWALL.LOG and the
size limit is 4096 KB.
The ICMP tab lets you select the requests for
information from the Internet that the
computer will respond to.
25
ICF Considerations




ICF is available in the Windows XP Professional 32-bit
edition and Windows XP Home Edition, but not in the
Windows XP Professional 64-bit edition.
ICF should be enabled on your shared Internet
connection if your network is using ICS to provide
Internet access to multiple computers.
ICF protects a single computer that is connected to
the Internet with a cable modem, a Digital Subscriber
Line (DSL) modem, or a dial-up modem.
ICF should not be enabled on VPN connections or on
client computers; it will interfere with file and print
sharing.
26
ICS


ICS lets you use one connection to connect multiple
computers on your home or small business network
to the Internet.
ICS host




Connect one of the computers on your network to the
Internet.
Enable ICS on this computer and it becomes the ICS host.
Other computers on the network connect to the Internet
through the host.
ICS is available in the Windows XP Professional 32-bit
edition and Windows XP Home Edition, but not in the
Windows XP Professional 64-bit edition.
27
Enabling and Disabling ICS
1.
2.
3.
4.
Click My Network Places, and then click View
Network Connections.
Click the dial-up, LAN, PPPoE, or VPN Internet
connection that you want to share.
In the Network Connections window, under Network
Tasks, click Change Settings Of This Connection.
In the Properties dialog box for the connection, in the
Advanced tab


Enable ICS by selecting the Allow Other Network Users To
Connect Through This Computer’s Internet Connection check
box
Disable ICS by clearing the Allow Other Network Users To
Connect Through This Computer’s Internet Connection check
box
28
Configuring ICS

The Allow Other Network Users To Control Or Disable The
Shared Internet Connection check box is available when
you enable ICS.




Select this check box to enable client control for the shared
Internet connection.
If client control is enabled, users can connect or disconnect
the Internet connection.
Clear this check box to disable client control for the shared
Internet connection.
In the Advanced tab of the Properties dialog box for the
connection, click Settings to view a list of the available
services that are enabled for this connection.

You can add to, remove from, and configure the services in
this list.
29
ICS Considerations

Do not use ICS on networks with any of the
following:





Microsoft Windows 2000 Server domain controllers
Domain Name System (DNS) servers
Gateways
Dynamic Host Configuration Protocol (DHCP)
servers
Computers configured for static IP addresses
30
ICS Considerations (Cont.)

The ICS host computer needs two network
connections:




The first, the LAN connection, is automatically created by
installing a network adapter card, which connects it to the
other computers on the network.
The second connection uses a dial-up modem, ISDN, DSL
modem, or high-speed connection to connect to the
Internet.
Enable ICS only on the connection to the Internet.
Enabling ICS automatically assigns a static IP address
to the LAN connection to the network.
31
Network Bridge




Lets you connect LAN segments (groups of network
computers) without using routers or bridges
Lets you connect different types of network media
Automates the configuration that is required to
forward information from one media type to another
Uses the Institute of Electrical and Electronics
Engineers (IEEE) Spanning Tree Algorithm (STA)


STA provides an automated mechanism to ensure that the
forwarding topology is loop free.
You do not have to do any configuration to use Network
Bridge for STA.
32
Creating A Network Bridge

5.
Click Start, and then click My Computer.
Click My Network Places, and then click View
Network Connection.
In the Network Connections window, under LAN Or
High-Speed Internet, click one of the private network
connections that you want to make part of the
bridge.
Hold down the Ctrl key and click each of the other
private network connections that you want to make
part of the bridge.
Right-click one of the selected private network
connections, and then click Bridge Connections.
33
Network Bridge Considerations

Only the following adapters can be part of the
Network Bridge:





Ethernet adapters
IEEE-1394 adapters
Ethernet-compatible adapters
Adapters that have ICF or ICS enabled cannot
be included in the Network Bridge.
You can add other private network
connections to the Network Bridge after it has
been created.
34
Network Bridge Considerations
(Cont.)



Only one bridge can exist on a Windows XP
Professional computer, but it can be used to
connect as many different media types as the
computer can accommodate.
You cannot create a bridge connection on
computers running Microsoft Windows 2000
or an earlier version of Microsoft Windows.
Network Bridge is available in the Windows
XP Professional 32-bit edition and Windows
XP Home Edition, but not in the Windows XP
Professional 64-bit edition.
35
Network Setup Wizard



This wizard is one of the home and small business
components in Windows XP Professional.
It is only available in a workgroup environment.
You first run the Network Setup Wizard on the
computer that will be your ICS host.



The Network Setup Wizard automatically enables ICS and
ICF.
After you run the Network Setup Wizard on the ICS
host computer, you run it on the other computers in
the network.
The Network Setup Wizard configures all of the
computers on the network so that they function
properly in the network.
36
Running The Network Setup Wizard

Chapter Summary

All of the processes for creating inbound and
outbound network connections are consolidated in
the New Connection Wizard.





You choose and configure the devices on your computer that
you will allow to accept incoming calls.
You specify which user accounts can use an inbound
connection.
You specify whether to allow callback for each user account.
You can create a shortcut on your desktop for any
connection you create using the New Connection
Wizard.
ICF restricts the information sent between your
network and the Internet.
38
Chapter Summary (Cont.)



of the following:






Windows 2000 Server domain controllers
DNS servers
Gateways
DHCP servers
Computers configured for static IP addresses
