You need to add rules that enable ICMPv4 and ICMPv6 packets to pass through your firewall?

To permit ICMPv4 and enable you to ping other computers by their IPv4 addresses, enter the following in an elevated command prompt on all computers on your network:

netsh advfirewall firewall add rule name="ICMPv4" protocol=icmpv4:any,any dir=in action=allow

To permit ICMPv6 and enable you to ping other computers by their IPv6 addresses, enter the following in an elevated command prompt on all computers on your network:

netsh advfirewall firewall add rule name="ICMPv6" protocol=icmpv6:any,any dir=in action=allow

Remember that in Windows 7, you cannot ping other computers on your network by default.
