Why doesn my VMware, VirtualPC or Parallels work?

Symptom: When a wireless client has a virtual machine running on it (e.g. in VMware, VirtualPC or Parallels), then the Wireless Controller DHCP relay may drop DHCP packets from the VM client, with a “dhcpProxy: Dropping packet (no mscb)” message. Conditions: The virtual machine is operating in bridged mode, rather than in NAT (“shared networking”) mode. Workaround: Configure the virtual machine software for NAT (“shared networking”) mode, not bridged mode. This is a known Cisco Bug “CSCsq46427”. The Wireless team is working closely with Cisco on this issue and a solution should be forth-coming in a future code release.
