How to achieve sharing after the firewall in Windows XP

By opening the "Internet Connection Firewall" built into Windows XP system, we can surf the Internet with peace of mind, but after opening the "Internet Connection Firewall", we will find that it can not be used normally. The network sharing feature is gone. "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 "network sharing" rule we want to use, 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 is: 135, 136, 137, 138, 139, 445, which is to enter 6 times in order. The above 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" can coexist peacefully.
