The virtual machine ping does not pass the host, but the host can ping the virtual machine (reproduced)

I installed the virtual machine in the Windows7 system, through the virtual machine installed Ubuntu13.04, I set the host and the virtual Machine connection mode is bridged, installed, found that the virtual machine ping does not host, but the host can ping the virtual machine.

My operation is: Turn off the firewall and discover that the virtual machine can ping the host. Description is blocked by the Windows7 firewall.

the question now is: If I keep shutting down the firewall, isn't that a thing ? Doing so will affect my computer's security. So I think I need to first determine what the firewall is blocking, causing the firewall to be shut down?

So I check the information on the Internet, the original is Windows7 firewall does not open icmpv4-in This rule, how to open it:

1. Open WIN7 Firewall

2. Select Advanced Settings

3. Inbound Rules

4. Locate the file and print sharing (Echo request –icmpv4-in) rule with the profile type public, set to allow.

5. The virtual machine can ping the host!
