Hello, I have a customer that is looking to deploy the below scenario and is looking to see if this is a limitation or if there’s another way of making this architecture work:
Deployment scenario:
VM (e.g. SGT B) -> Microsoft OS (e.g. SGT A) -> Wireless -> SDA fabric
Customer summary of what they ran into:
“As for Wifi, essentially due to how Wifi works, even though the VM is bridged through the base OS vswitch, it uses the Host MAC in the wifi frames. The WLC already has the MAC associated to the host IP and just doesn’t forward the DHCP discovers. In theory this is kinda good behaviour. It stops some potential DHCP exhaustion attacks and so forth, but it breaks enabling bridged VM’s over wireless. So essentially people are at home on crappy wifi and the Router is too dumb to care and VM’s work. They come into the office and stuff doesn’t work leading to the wifi being “garbage/crappy/unkind names”
There was a work around that involved like turning of Proxied DHCP/ARP/enabling passive client. But, it may need Multicast and couldn’t be used with an 802.1x SSID or some such. I was never able to get a straight answer out of TAC.”
Any thoughts, advice, guidance, would be greatly appreciated.
