I setup 6 virtual machines on the Azure and configured them in the same network (192.168.0.0-192.168.62), once i start 4 of them i can find each one got a IP address like this :
Machine 1 : 192.168.0.4
Machine 2 : 192.168.0.5
Machine 2 : 192.168.0.6
Machine 2 : 192.168.0.7
i remote desktop to anyone of them and try to ping others, the ping cannot work, i tried to follow some guides to enable the ICMPv4&ICMPv6 for inbound traffic on the Windows firewall setting, but ping still cannot work.
Since i have a SQL server installed on one machine, i tried to connect to it from other machines, but it cannot work either, the point is these servers can communicate before.(these virtual machines were deleted on time, and i re-create them from the disk.
since disk are not deleted when you delete the virtual machine, everything on the virtual machine just like before)
Waiting for your feedback.
Many thanks
William
