I had tried VLAN creating a VLAN pool in between the virtual boxes. But even after installing VLAN in client box, despite all the interface configurations, it is not pinging the other system in the same VLAN.
I had created a bridged interface for pinging the outer world and another intnet internal network for interconnecting the virtual boxes, in both the machines.
Virt boxes are pinging each other thorugh other interfaces, it is pinging outer world through the main interface eth0. Still not communicating via the VLAN interface. What is the reason behind it?
