To solve the problem that software cannot be connected to the network, you can add the program to the Windows Firewall exception. The specific steps are as follows: 1. Open Control Panel > Windows Defender Firewall, click Allow Apps or Functions to pass through the Firewall, click Change Settings, select Allow another App, browse and select the program's .exe file, and then select the dedicated and public networks; 2. Check the inbound and outbound rules in the Advanced Security Firewall to confirm whether there are rules that block the program, and if there are any, disable or modify to allow; 3. Use the command line to quickly release, execute the netsh advfirewall firewall add rule name="Allow MyApp" dir=in program="C:\\Program Files\\MyApp\\myapp.exe" action=allow command to add inbound rules, or add the dir=out parameter to handle outbound traffic.

Sometimes after installing a new software, you will find that it cannot be connected to the Internet. At this time, the Windows firewall may be "blocking the way". It is not complicated to let an application pass through the firewall. Just find the correct setting path and you can do it in a few steps.

Add program exception: manually release an intercepted app

If you find that a program cannot access the network, you can manually add it to the firewall allow list.
The operation method is as follows:

• Open Control Panel > Windows Defender Firewall
• Click on the Allow App or Feature on the left to go through the Windows Defender Firewall
• Click Change Settings in the list (Administrator permission is required)
• Click Allow another application , and browse the local file system to select the program you want to release (usually the .exe file in the installation directory)
• After selecting it, click "Add" and make sure that both "Dedicated" and "Public" are selected (unless you know which network you only need)

Note: Some programs will automatically pop up firewall prompts, and then select "Allow connections" to do so. If there is no automatic prompt, you have to add it manually.

Check if existing rules block the app

Sometimes it is not that it is not added, but that there are specific rules that block it.
You can check this way:

• Enter the Advanced Security Windows Defender Firewall
• Select Outbound Rules or Inbound Rules on the left
• Find entries related to the target program in the list on the right
• If you see that a rule is "block connection", right-click and select "Properties" to see if its program path matches your App
• If it is confirmed that it is a mistake, you can temporarily disable this rule or modify it to allow

This approach is suitable for situations where exceptions have been tried but the problem remains the same.

Quick release of the app using the command line (advanced operations)

If you are familiar with the command prompt, you can also use one line of command to release a program:

 netsh advfirewall firewall add rule name="Allow MyApp" dir=in program="C:\Program Files\MyApp\myapp.exe" action=allow

The above command means: add an inbound rule to allow programs with specified paths to pass through the firewall.
Similarly, you can also add dir=out to handle outbound traffic.

This method is suitable for batch processing or scripting automation settings.

Basically these are the operations. The key to releasing an app is to correctly identify the program path, select the appropriate network type, and pay attention to whether there are conflicting rules. Although the steps seem a bit too many, it is very fast to actually operate. The key is not to choose the wrong program path.
