20. 20 Home and Small Business Components Internet Connection Firewall (ICF) Internet Connection Sharing (ICS) Network Bridge

21. 21 Understanding Firewalls A firewall Protects a network against external threats from another network, including the Internet Prevents an organization’s networked computers from communicating directly with external computers Prevents external computers from communicating directly with an organization’s networked computers Audits network activity All incoming and outgoing communication is routed through a proxy server outside the network.

22. 22 Enabling and Disabling ICF 1. Click Start, and then click My Computer. 2. Click My Network Places, and then click View Network Connections. 3. Click the dial-up, local area network (LAN), or high-speed Internet connection that you want to protect. 4. In the Network Connections window, under Network Tasks, click Change Settings Of This Connection.

23. 23 Enabling and Disabling ICF (Cont.) 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 And Network By Limiting Or Preventing Access To This Computer From The Internet check box

24. 24 Configuring ICF In the Properties dialog box for the connection, in the Advanced tab, click Settings to display the Advanced Settings dialog box. Use the Advanced Settings dialog box to configure ICF. The Services tab lets you specify the services running on your computer that Internet users can access.

25. 25 Configuring ICF (Cont.) 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.

26. 26 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.

27. 27 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.

28. 28 Enabling and Disabling ICS 1. Click My Network Places, and then click View Network Connections. 2. Click the dial-up, LAN, PPPoE, or VPN Internet connection that you want to share. 3. In the Network Connections window, under Network Tasks, click Change Settings Of This Connection. 4. 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

29. 29 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.

30. 30 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

31. 31 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.

32. 32 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.

33. 33 Creating A Network Bridge 1. Click Start, and then click My Computer. 2. Click My Network Places, and then click View Network Connection. 3. 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. 4. Hold down the Ctrl key and click each of the other private network connections that you want to make part of the bridge. 5. Right-click one of the selected private network connections, and then click Bridge Connections.

34. 34 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.

35. 35 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.

36. 36 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.

37. 37 Running The Network Setup Wizard 1. Click Start, and then click Control Panel. 2. Click Network And Internet Connections. 3. Click Network Connections. 4. In the Network Connections window, under Pick A Task, click Setup Or Change Your Home Or Small Office Network.

38. 38 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.

39. 39 Chapter Summary (Cont.) ICS lets you use one connection to connect multiple computers on your home or small business network to the Internet. ICS should not be used on networks that contain any of the following: Windows 2000 Server domain controllers DNS servers Gateways DHCP servers Computers configured for static IP addresses Network Bridge lets you connect LAN segments without using routers or bridges.
