What we are trying to achieve is that vx9000 should not be connected to the existing private network. We will be having a dedicated leased line from our ISP to be configured on it. Then connect some APs for internet distribution. I'm not sure if you get what I am trying to say, my English is not that good. i am also new to wireless technology. Thanks
I am afraid that the part of hypervisor is out of my scope and level of knowledge.
You could do a simple routing rules on your VM server and VX9000 will be easily accessible from ISP side, but again - this is out of VX configuration scope.
In the end, only thing that matters here is how physical connection traverses the hypervisor to the virtual machine. WiNG system is ready to use whatever IP address you supply it with.
