How to Let a Ping Through a Windows Firewall
Windows Firewall blocks hackers, worms and viruses that try to come through your computer via the Internet. If you do not use a firewall, these can get through and do damage to your computer. A firewall is one of the defenses that protects your computer from these threats. Windows Firewall has a feature that allows you to allow pings to get through.
Click "Start," "Control Panel" and "Windows Firewall." Make sure Windows Firewall state is "On" by looking under Home or work (private networks). Click on "Advanced settings" on the left side.
Right-click on "Inbound Rules" and select "New Rule." Select "Custom Rule" and click "Next." Select "All programs" and click "Next."
Select "ICMPv4" under Protocol type on the right side. Click "Scope" on the left side and choose "Any IP addresses" under "Which local IP addresses does this rule apply to?" Choose "Any IP addresses" under "Which remote IP addresses does this rule apply to?"
Click "Action" on the left side, select "Allow" and click "Next."
Click "Profile" on the left side. Check all three check boxes, "Domain" (applies when a computer is connected to a network), "Private" (applies when a computer is connected to a Private Network Location) and "Public" (applies when a computer is connected to a Public Network Location.) Click "Next."
Click "Name" on the left side. Name the rule in the "Name" field.
