Windows XP Personal Network Online firewall five steps

A firewall is a set of software or hardware that helps protect your computer from hackers and many computer viruses. Therefore, you should install a firewall before you connect your computer to the network.

If you are using a Windows XP operating system, you can use its built-in network firewall.

It is worth noting that the network online firewall operates by blocking certain types of potentially harmful network traffic, so it can also block some useful network traffic. For example, using a network to share files or printers, instant messaging applications such as transmission files, or as hosts for multiplayer games. But we still strongly recommend using a firewall because it helps to protect your computer immediately.

First step: Open the Internet Network firewall. Click [Start] and select [Control surface] to enter the following page, as shown in Figure 1.

Step Two: Select Network and Internet connections, and then press [network Connections], as shown in Figure 2.

Step three: Under the [LAN] or [high-speed Internet] heading, click the icon to select the connection you want to help protect, as shown in Figure 3.

Fourth step: In the work pane on the left, under Network Tasks, click Change settings for this connection.

Alternatively, click the right mouse button on the local connection, and then press [Properties], as shown in Figure 4.

Fifth step: On the Property Index volume label, under [Advanced], select the box next to [Protect my computer and network by restricting or preventing access to this computer from the Internet], as shown in Figure 5.

Choose this box to protect your computer and network.

After you select this box and close the Content window, the firewall opens. Firewalls can interfere with certain network operations, such as file and print sharing, network-related programs, or online games.

Using firewalls is just the first important line of defense for computer security, and you should also use Windows Update and antivirus software to help secure your computer.
