VirtualBox, Realtek NIC, and VLANs?
I can't seem to make my system with the following configuration work with VLANs.
OS: Windows 8.1 Pro
NIC: 2x Realtek 8111E PCI-E GBE
VM: VirtualBox 4.3.14
OS: PfSense 2.1.4
Virtual NIC 1: Intel PRO/1000 MT Desktop 82540EM - Bridged to Realtek - em0
Virtual NIC 2: Intel PRO/1000 MT Desktop 82540EM - Bridged to Realtek - em1
When I have tagged packets they seem to get dropped. I'm using a workaround that's below which is more of a "band-aid" solution. But in doing so I can no longer have a untagged VLAN. Also, I'm severely limited to the number of VLANs I can create because I'm creating virtual adapters in Windows to bridge with PfSense.
The "Realtek PCIe GBE Family Controller" NIC can be configured to not strip the vlan tags, by going to the Adapter Settings and setting "Priority & VLAN" to "Priority & VLAN disabled"
