How to make your VirtualBox Windows Guest echo the IPv4 ping request?

1. Bridged network on a wired connection.
2. Control Panel -> Systems and Security -> Windows Firewall -> Advanced Settings -> Inbound Rules -> (Enable) File and Printer Sharing (Echo Request - ICMPv4-In)
3. (only for my company) If the guest get a 172.16.100.xxx IP with 255.255.255.0 subnet mask and 172.16.100.1 gateway, release the IPAddress and visit 172.16.100.1 by IE, then register your account for a renewed IP.
