Recently in the server configuration, want to in their own virtual machine test, but the first step that stumped me
Online methods are said need to shut down the virtual machine and host firewall, and I've tried really feasible,
But it's more like a pick up the sesame lost watermelon, solve the small problem is a bigger problem,,,
I don't want to close the firewall, after all, still can have a little effect, I now want to know more details of which rules to prevent virtual machine and the communication between hosts? Or how can I want to know the firewall to stop the communication connection?
Google along while of this one is the only a somewhat related:

Say need to enable file and print sharing (echo request - ICMPv4 -) In this rule, but after I test and no effect, as can't opened the
Great god answer ah, how can I need to know what is specific rules to prevent virtual machine and the communication between hosts?
Or firewall is there similar to be blocked communication log files, you can find out specific what went wrong

Test fort opportunities to this kind of situation, don't want to close the firewall, and want to host can reach each other on both ends, can explain the inbound firewall rules by default filtering icmp packet, the icmp protocol is a script, no port number, so wish to have a virtual machine ping needs in the physical machine - advanced Settings - the inbound firewall rules of the new rules. Choose custom, agreement icmpv4 choice, and then go all the way down the points down, finally can ping, if the security requirements of high, will use remote desktop MSTSC, that can modify the RDP protocol is the default port 8843, literally change the port number, is also a change in the inbound rules.

junction post bar, do you like this, this software haven't through the Virtual machine, first go to learn the Virtual machine, Virtual machine Network model is divided into three kinds, respectively be Bridged, NAT (Network Address Translation), the Host - only, translated into Chinese bridge, Network Address Translation, only the Host, this three patterns can be linked to the Host, three models in the Virtual Network editor to see that your Network is configured to pass, it is none of you said file sharing and firewall, firewall, don't you set the default is not connected to the PING, also to enter the rules, PING using icmp protocol
