I am running Fusion Pro 6.0.2 on a Mac w/ 10.9.0. The Mac has onboard Ethernet plus a couple of USB Ethernet adapters. The USB adapters are connected to a switch with ports on varying VLANs, however they recieve untagged frames. The onboard Ethernet is connected to the same switch, and sees VLAN1 as untagged and the other VLANs as tagged.
If I create a 'VLAN100' interface in OS X and bridge my virtual machine NIC to it, the Ethernet frames sent out of the physical Ethernet interface of the Mac have the MAC of the VLAN/Ethernet interface instead of the virtual machine MAC. If if bridge directly onto one of the USB Ethernet adapters (on the same VLAN, but not tagging) the frames go out with the MAC of the virtual machine NIC. Running wireshark against the vlan0 interface, as well as the en0/en2 interfaces indicate the frames have the 'wrong' MAC address by the time they hit the interface, so it seems to be something within the VMware bridge/vSwitch that is modifying the MAC address of the frame.
I've not figured out how to pass tagged frames directly into the VM, but clearly the virtual interfaces don't behave as expected.
Has anyone else been successful running VLAN interfaces with Fusion and had it work properly?
