The Windows 10 firewall is a crucial security feature that protects your computer from unauthorized access and malicious activities. It acts as a barrier between your system and the internet, controlling incoming and outgoing network traffic. While the firewall is essential for security, it can sometimes block legitimate programs from accessing the internet or communicating with other devices on your network. In this article, we will explore the programs that should be allowed through the Windows 10 firewall and provide guidance on how to configure the firewall settings safely.
Understanding Windows 10 Firewall Basics
Before we dive into the programs that should be allowed through the firewall, it’s essential to understand how the Windows 10 firewall works. The firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It can be configured to block or allow specific programs, ports, and protocols.
The Windows 10 firewall has three main profiles:
- Domain profile: This profile is used when your computer is connected to a domain network.
- Private profile: This profile is used when your computer is connected to a private network, such as a home network.
- Public profile: This profile is used when your computer is connected to a public network, such as a coffee shop or airport Wi-Fi.
Each profile has its own set of rules and settings that can be configured to control incoming and outgoing traffic.
Allowing Programs through the Firewall
To allow a program through the Windows 10 firewall, you need to create a new rule. Here’s how to do it:
- Go to Control Panel > System and Security > Windows Defender Firewall.
- Click on Advanced settings on the left side of the window.
- In the Windows Defender Firewall with Advanced Security window, click on Inbound Rules or Outbound Rules, depending on the type of rule you want to create.
- Click on New Rule in the right-hand Actions panel.
- Follow the prompts to create a new rule, selecting the program you want to allow and the type of traffic you want to permit.
Essential Programs to Allow through the Firewall
While the specific programs you need to allow through the firewall will depend on your individual needs and usage, here are some essential programs that are commonly allowed:
- Web browsers: Google Chrome, Mozilla Firefox, Microsoft Edge, etc.

Allowing Ports and Protocols
In addition to allowing specific programs, you may also need to allow certain ports and protocols through the firewall. Here are some common ports and protocols that are often allowed:
- HTTP (port 80): For web browsing and online services.
- HTTPS (port 443): For secure web browsing and online services.
- FTP (port 21): For file transfers.
- SSH (port 22): For secure remote access.
- RDP (port 3389): For remote desktop connections.
Configuring Firewall Settings for Specific Programs
Some programs may require specific firewall settings to function correctly. Here are a few examples:
- Skype: Skype requires incoming and outgoing traffic on ports 80, 443, and 5222-5223.
- TeamViewer: TeamViewer requires incoming and outgoing traffic on ports 80, 443, and 5938.
- Steam: Steam requires incoming and outgoing traffic on ports 80, 443, and 27015-27030.
Using the Windows Defender Firewall with Advanced Security
The Windows Defender Firewall with Advanced Security is a powerful tool that allows you to configure detailed firewall settings. Here are some tips for using this tool:
- Create separate rules for incoming and outgoing traffic: This will give you more control over the type of traffic that is allowed through the firewall.
- Use the “Scope” tab to specify IP addresses: This will allow you to restrict traffic to specific IP addresses or subnets.
- Use the “Protocols and Ports” tab to specify protocols and ports: This will allow you to restrict traffic to specific protocols and ports.
Best Practices for Configuring the Windows 10 Firewall
Here are some best practices to keep in mind when configuring the Windows 10 firewall:
- Only allow necessary programs and ports: This will help to minimize the attack surface and reduce the risk of security breaches.
- Use strong passwords and authentication: This will help to prevent unauthorized access to your computer and network.
- Keep your firewall settings up to date: This will help to ensure that your firewall is configured to block the latest security threats.
- Monitor your firewall logs: This will help you to detect and respond to potential security incidents.
Common Mistakes to Avoid
Here are some common mistakes to avoid when configuring the Windows 10 firewall:
- Allowing all incoming and outgoing traffic: This will essentially disable the firewall and leave your computer vulnerable to security threats.
- Allowing unnecessary programs and ports: This will increase the attack surface and reduce the effectiveness of the firewall.
- Failing to keep firewall settings up to date: This will leave your computer vulnerable to new security threats.
Conclusion
The Windows 10 firewall is a powerful security tool that can help to protect your computer from unauthorized access and malicious activities. By understanding how the firewall works and configuring it correctly, you can help to ensure the security and integrity of your computer and network.

What is Windows 10 Firewall and how does it work?
Windows 10 Firewall is a security feature that helps protect your computer from unauthorized access and malicious activity by controlling incoming and outgoing network traffic. It works by blocking or allowing specific programs to communicate through the internet, based on a set of predefined rules.
By default, Windows 10 Firewall is enabled and configured to block most incoming connections, while allowing outgoing connections. However, you can customize the settings to allow specific programs to communicate through the firewall, either by adding them to the allowed list or by creating custom rules.
How do I allow a program through Windows 10 Firewall?
To allow a program through Windows 10 Firewall, you can follow these steps: Go to Control Panel > System and Security > Windows Defender Firewall. Click on “Allow an app or feature through Windows Defender Firewall” on the left side of the window. Then, click on the “Change settings” button and check the box next to the program you want to allow.
If the program is not listed, you can click on the “Allow another app” button and browse to the program’s executable file. Once you’ve added the program, make sure to check the boxes next to the network types you want to allow it to communicate through (e.g., Domain, Private, or Public).
What is the difference between allowing a program through the firewall and creating a custom rule?
Allowing a program through the firewall is a straightforward process that adds the program to the allowed list, enabling it to communicate through the internet. Creating a custom rule, on the other hand, allows you to specify more detailed settings, such as the protocol, port, and IP address, to control how the program communicates.
Custom rules provide more granular control over the program’s network activity, which can be useful for advanced users or for programs that require specific settings to function properly.
