Virtualbox

If you use VirtualBox, you will have to update your VM network settings. Open the settings panel for the VM, go the the "Network" tab, pull down the "Advanced" settings. Here, the "Adapter Type" should be pcnet (the full name is something like "PCnet-FAST III"), instead of the default e1000 (Intel PRO/1000). Also, "Promiscuous Mode" should be set to "Allow All". If you don't do that, bridged containers won't work, because the virtual NIC will filter out all packets with a different MAC address.
