How to cancel the ban ping command in Win7 system?

When I ping the ip of the machine in the Linux system of the virtual machine, I found that the ping is unreachable, and the machine can ping the ip in the virtual machine. It should be for security reasons, Win7 is disabled by default in the firewall.

1. View host ip

Open “Start”"attachment" in the program, find “command prompt”open. Enter the command: ipconfig, you can see that the ip of the machine is 192.168.0.111, the gateway is 192.168.0.1

2, check the ip

Enter the command at the command prompt: ping 192.168.0.101 , see that the ping has been pinged, and the packet is received normally.

Enter the command in the terminal: ping 192.168.0.111, and wait for a long time without pinging.

5. Ping the gateway in the virtual machine system

Because the ping fails, check if the gateway can ping. If the gateway can ping, the problem is that the settings on this machine may prevent others from pinging it. Enter the command at the terminal: ping 192.168.0.1, and you can see that the gateway can be pinged normally.

See two items. Both are not enabled. Right click on the two items and select “Enable Rules”.

After the modification is completed, return to the virtual machine system and enter the command in the terminal: ping 192.168 .0.111, you can see that it can be pinged normally.
