Hello

Anyone have faced this problem?  CS4.02 KVM Advanced Network, VM instance
can not access public IP.  NAT(Source)


That the VM instance running, but inside the VM instance, it is not
possible to access outside.


It can ping VMs each other,   It can ping google.com in the* Virtual Router
VM.*

But just can not ping Google.com inside the VM instance.


Seems inside the VM instance,  It can resolve the Google.com 's IP address.
BUT can not do others.

Please see the following output.
