I want to disable the firewall of the last two virtual NICs. I don't know what to do. The steps are as follows:
(1) Click "Control Panel" and "network connection" in sequence ".
(2) Click "Change Windows Firewall settings" in "Network tasks" on the left, and click the "advanced" tab.
(3) In the "advanced" section "network connection settings", remove the check boxes before vmnet1 and vmnet8 and click "OK ". For example:

When a thread calls a Java method, the virtual opportunity creates a new stack frame and presses it into the Java stack. When it calls the local method, the virtual machine keeps the Java stack intact, n

We recommend that you have at least two network adapters on the server running hyper-V, one of which is dedicated for remote management, one or more network adapters are dedicated to virtual machines (subpartitions). If you are using shared network storage such as San and iSCSI, you need two high-speed (Gbit copper o
