Question 2: How to set the forbidden port on the firewall? As long as the factory is not allowed to open, it is forbidden by default. Don't deliberately prohibit it, as long as you don't open the port. The arson wall sometimes prompts what applications access the network and through what ports. As long as you don't allow it, the port will not open.
Otherwise, you can use TCP-IP to filter ports:
1. Right-click My Neighbors, select Properties, and then double-click Local Area Connection (if you are a dial-up Internet user, select My Connection icon) to open the Local Area Connection Status dialog box.
2. Click the [Properties] button to open the Local Connection Properties, select "Internet Protocol (TCP/IP)" in "This connection uses the following items", and then click the [Properties] button.
3. In the pop-up "Internet Protocol (TCP/IP)" dialog box, click the [Advanced] button. In the pop-up advanced TCP/IP settings, select the Options tab, select TCP/IP filtering, and then click the [Properties] button.
4. In the TCP/IP filtering dialog box that pops up, select the check box to enable TCP/IP filtering, and then select "Allow Only" on the TCP port on the left.
Question 3: How to set the Windows 7 firewall port rule 1?
Click the Start button, and then click the Control Panel item in the pop-up menu.
In the control panel window that pops up, click windows Firewall.
Click Advanced Settings on the left side of the pop-up window to enter the Advanced Security windows Firewall Settings item.
If you want to set the firewall policy, it is mainly aimed at setting the entry and exit rules of ports, that is, telling the system which door (port) can let what kind of people (links) enter and exit, and how to enter and exit. Therefore, we need to set inbound and outbound rules, click the inbound rule on the left, and then click the New Rule button in the action item on the right to open the window.
Select the port, and then click Next.
Select TCP and select a specific local port. Enter the port number in the input box at the back, such as 10 12, and click Next.
Select the specified operation and click Next to allow the connection.
Select the network to which the rule applies. By default, all is selected. Just use the default. Click Next.
Name and describe the new rule, and then click Finish.
At this time, return to the windows firewall settings window, click the entry rule item, and you can see our new firewall entry rule. Because the network connection is generally two-way, it is not enough for us to just set the inbound rules. We also need to set the entry rules and continue to look down.
In fact, the setting of outbound rules is the same as that of inbound rules. Click the outgoing rule item, click New Rule on the right, and repeat steps 5-9 in the pop-up window to create outgoing rules. At this point, a firewall rule for a port has been established!

Question how to set up the open port control panel \ system and security \Windows firewall for win7 firewall? Click on the advanced settings on the left, which should be what you want.
Then create a new rule in advanced settings.
Question 6: How to modify the port settings of the firewall? TCP and UDP are both transport protocols of IP layer, and they are processing interfaces between IP and upper layer. TCP and UDP protocol port numbers are used to distinguish the IP addresses of multiple applications running on one device.
Since multiple network applications may run on the same machine, the computer needs to ensure the correctness of the software application that receives the data packet from the source host on the target computer and that the response can be sent to the correct application of the source host. This process is achieved by using TCP or UDP port numbers. In TCP and UDP headers, there are "source port" and "destination port" segments, which are mainly used to display identification information when sending and receiving. Together with the port number, the IP address is called "socket".
IETF IANA defines three kinds of port groups: well-known ports, registered ports and dynamic and/or dedicated ports.
The well-known ports range from 0 to 1023.
The registered ports range from 1024 to 49 15 1.
Dynamic and/or dedicated ports range from 49 152 to 65535.
The problem of changing TCP and UDP ports is a firewall problem. Permission rules can be added to the firewall, which has nothing to do with antivirus software.
Question 7: How to add a port to the firewall that comes with Win7? You can open the firewall from the Control Panel, and then click "Allow programs and features to pass through the windows7 firewall" to add the programs you want to add.
Question 8: How to set firewall interception? Click Start → Control Panel, and then double-click Windows Firewall in the classic view of Control Panel to open the Windows Firewall console. In addition, you can open the firewall console by clicking "Windows Firewall" under the new security center interface in SP2.
1. General Tab
There are two main options in the General tab of the Windows Firewall Console: enabled (recommended) and disabled (not recommended), and a sub-option "No exceptions allowed". If no exceptions are selected, Windows Firewall will block all network requests to connect to the user's computer, including applications and system services in the list of exceptions tabs. In addition, the firewall will intercept files and printers and detect network devices. The use of Windows firewall that does not allow exceptions is simply "behind closed doors", which is more suitable for "high-risk" environments, such as restaurants, hotels, airports and other places connected to personal computers on public networks.
2. Exceptions tab
Some programs need external communication, so they can be added to the Exceptions tab. The programs here will be authorized to provide connection services, that is, they can listen and accept connections from the network.
At the bottom of the exception tab interface, there are two add buttons, namely "Add Program" and "Add Port". You can manually add exceptions based on specific conditions. If you don't know through which port the application communicates with the outside world, or whether it is based on UDP or TCP, you can add an exception by adding a program. For example, to allow Windows Messenger to communicate, click the Add Program button, select the application "C: \ Program Files \ Messenger \ Messenger \ m * * SGS.exe", and then click OK to add it to the list.
If you are familiar with port numbers and TCP/UDP, you can adopt the latter method, that is, specify the way to add port numbers. For each exception, you can specify its scope by changing the scope. For home and small office application networks, it is recommended to set the scope to the possible local network. Of course, you can also customize the IP range in the scope to only accept network requests from a specific IP address range.
3. Advanced tab
The Advanced tab contains four groups of options: network connection settings, security records, ICMP settings and restoring default settings, which can be configured according to the actual situation.
◆ Network connection settings
Here, you can choose which connections Windows Firewall is applied to. Of course, you can also configure a connection separately, which can make the firewall application more flexible.
◆ Safety record
The logging of the new Windows firewall is similar to ICF, and the settings in the logging option can record the tracking records of the firewall, including all discarded and successful events. In the log file option, you can change the storage location of the log file or manually specify the size of the log file. The default option of the system is not to record any intercepted or successful events, and the size of the recording file is 4MB by default.
◆ICMP settings
Internet Control Message Protocol (ICMP) allows computers on the network to share error and status information. When selecting an item in the ICMP Settings dialog box, the corresponding description information will be displayed at the bottom of the interface, which can be configured as required. By default, all ICMP are not turned on.
◆ Default settings
If you want to restore all Windows firewall settings to the default state, you can click the "Restore to Default" button on the right.
Question 9: How to open the port blocked by firewall? BT download has become one of the important download methods for more broadband users, but why do many users with public IP download with BT so slowly? 10K or so, it is better to download by FTP. In fact, an important reason is that the firewall is installed on the user's machine, which blocks the connection from the external network. Other seeds can't actively connect to your machine, and of course the download speed will not be very fast. If a machine with a firewall wants to speed up BT download, it needs to let BT download software penetrate the firewall, which will lead to an affair. Here's how to make BT practice "walking through the wall".
The settings in the following common firewalls are all based on wind broadcast 1.0.0.7. The default listening port used by wind broadcast is 6699, so we need to set the firewall not to intercept the port of 6699. Of course, in the software, we can specify its listening port ourselves.
First, if XP comes with its own firewall.
Right-click the icon (two small TVs) at the bottom right of the desktop, and select "Change windows Firewall Settings" to open the exception option to see if funpaleyr is checked. Note: Please uncheck "No Exceptions" in the general options.
