For mobile users that frequently switch between wired and wireless network connections, this can be a problem. It would be ideal if !VirtualBox offered an ''Automatic'' setting which connected the guest's bridged network adapter to the host's physical interface using a set of rules such as the following: 1. If the guest's IP address (based on packet SRC?) matched a directly-connected subnet on the host, use the interface that connects to that subnet. 1. If the guest sends a DHCP request, route the request through the physical interface designated as the default route. 1. If the guest's IP address cannot be determined, or does not match any directly-connected subnets on the host, use the physical interface designated as the default route. An ''Automatic'' setting of this variety would only work for TCP/IP-based networking, but that's perfectly fine for the majority of applications. In cases where ''Automatic'' could not be used, a specific physical interface could still be selected." enhancement closed network VirtualBox 2.2.4 fixed bridged networking other other
