Enabling ICMP (Internet Control Message Protocol) on Windows 10 allows your computer to send and receive network diagnostic messages. This is particularly useful for troubleshooting network connectivity issues. To enable ICMP, you’ll need to adjust your Windows Firewall settings. The task can be completed in a few simple steps using the Windows Control Panel and Command Prompt.
How to Enable ICMP on Windows 10
By following these steps, you’ll be able to enable ICMP on your Windows 10 computer. ICMP is essential for network diagnostics, like the popular ping command. Enabling it involves tweaking settings in the Windows Firewall, ensuring that your computer can send and receive these important messages.
Step 1: Open Control Panel
First, open the Control Panel from the Start menu.
Open the Start menu by clicking the Windows icon in the bottom-left corner of your screen. Type "Control Panel" in the search bar and hit Enter. Click on the Control Panel app to open it.
Step 2: Navigate to Windows Defender Firewall
Next, go to Windows Defender Firewall within the Control Panel.
Once in the Control Panel, set the view to either "Large icons" or "Small icons" at the top right for easier navigation. Find and click on "Windows Defender Firewall."
Step 3: Advanced Settings
Then, open Advanced Settings to adjust firewall rules.
In the Windows Defender Firewall window, look at the left-hand side menu. Click on "Advanced settings." This will open the Windows Defender Firewall with Advanced Security window.
Step 4: Inbound Rules
Next, select Inbound Rules to create a new rule for ICMP.
In the Advanced Security window, look at the left-hand side again and click on "Inbound Rules." Here, you can manage rules that control incoming connections.
Step 5: New Rule
Create a new rule to allow ICMP traffic.
On the right-hand side of the Inbound Rules window, click on "New Rule." A New Inbound Rule Wizard will pop up. Select "Custom" and click "Next."
Step 6: Protocol and Ports
Specify the ICMP protocol and relevant ports.
In the Protocol and Ports step, select "ICMPv4" from the Protocol type dropdown menu. Click "Next" to proceed.
Step 7: Allow the Connection
Choose to allow the connection to permit ICMP traffic.
Select "Allow the connection" in the Action step. Click "Next" to continue.
Step 8: Profile
Define when this rule applies by checking the necessary profiles.
Check all three boxes: Domain, Private, and Public. Click "Next" to move on.
Step 9: Name the Rule
Name your new rule for easy identification.
In the Name step, type a descriptive name, such as "Allow ICMP." Optionally, add a description. Click "Finish" to create the rule.
After completing these steps, your computer will allow ICMP traffic, enabling network diagnostics and troubleshooting.
