operator limit is a account, the maximum allowable three devices connected at the same time,

A: network connection mode outside net -- -- -- -- -- -- -- cat router host
Virtual machine set up bridge to get to the Internet, Nat model can also get to the Internet,

network connection B: -- -- -- -- -- -- cat networks outside the host
Physical host machine via broadband dial-up Internet access is successful, the virtual machine is set to the bridge (the three models are set up: 1 bridge custom card; 2 bridge copy directly connect the physical network; 3 bridge, copy directly connect the physical network + check the network connection state) as long as it is the bridge mode even light cat can't get to the Internet, Nat mode can normal Internet ,

Why can't ask this kind of connection cases by bridging model on the Internet? Is it because the cat to identify the physical host machine have a card 1, cat identify virtual machine have another card 2, believed to be two devices at the same time online?

May be, I also met this problem, but the MAC address can change, you can either put the virtual machine in the network card address change with the host, and see what happens

Which to science the principle of the network

Thank you for your reply

I understand: the current way of bridging is equivalent to through exchange connection, which is on the second floor, so the IP address configuration access to yourself and

If want to get to the Internet, and want to make virtual machine as a server, you can set the NAT, and set the port forwarding,
In the virtual machine file - & gt; Preference, a pop-up dialog box select on the left side of the network, and then select NAT network, to create a new, to edit, edit dialog box with a port forwarding, the configuration is ok
