Windows XP practical tips: secure sharing behind a firewall

        By turning on the "Internet Connection Firewall" built into the Windows XP system, we can surf the Internet with peace of mind, but after turning on the "Internet Connection Firewall", we will find that the "Network Sharing" function is not working properly. "Internet Connection Firewall" also banned our commonly used "network sharing" function when blocking malicious programs.

Is there a way to enable both the "Internet Connection Firewall" and the "Network Sharing" feature? The answer is of course affirmative. The following content of this article describes how to achieve the "Internet Connection Firewall" and "network sharing" how to coexist.

First of all, in order to set up the shared directory for the security of the computer, we should set the user name and password for each shared directory.

Next, we can make the "Internet Connection Firewall" and "Network Sharing" coexist peacefully through the following steps.

Right-click in "Network Connection" in the Control Panel and select "Properties" from the pop-up menu. Select the "Advanced" tab in the properties dialog and click on the "Settings" button. The "Advanced Settings" page shown in Figure 1 pops up.

Figure 1 Advanced Settings Page

In the advanced settings page shown in Figure 1, we saw several common network services listed, but there is no such thing as we use. Network sharing rules, so we need to add rules. Click the "Add" button in Figure 1 to bring up the "Service Settings" page as shown in Figure 2.

Figure 2 Service Settings Page

Enter the following in the Figure 2 page:

Service Description: File Sharing Port Number

Computer Name and IP Address: 127.0.0.1

External port number for this service: Port number

Internal port number for this service: Port number

The port number here is: 135, 136, 137, 138, 139, 445, that is, enter 6 times in order.

The above setting is the TCP service, but we also need to use the UDP service, so we have to enter 6 times according to the previous steps, just change the selected TCP shown in the page of Figure 2 to UDP.

After the above settings, you will find that "Internet Connection Firewall" and "Network Sharing" have been able to coexist peacefully
