Enabling Network on VirtualBox with Mobile Broadband

Question

I have set up a Windows7 VM on Virtual Box. Host OS is Ubuntu Oneiric. I am connected to internet on host OS using mobile connection. I want to use this connection on my VM as well. But I am unable to set up network on Virtual Box.

I googled for the solution. But most of them were either for Wireless or for wired connection. I tried few of them but in vain.

I am a newbie and don't have much idea how to do this. Please help me so that I can connect my VM to the host OS network.

My current network settings are as follows.

$ ifconfig
eth0  Link encap:Ethernet  HWaddr 18:03:73:6c:45:17  
      UP BROADCAST MULTICAST  MTU:1500  Metric:1

Solution

The problem is solved. I changed the network configuration on Virtual Box.

The configuration which enabled networking on guest OS is below.

Attached to:     NAT
Adapter Type:    Intel PRO/1000 MT Desktop (82540EM)
Promiscous Mode: Allow VMs
Cable Connected: Yes

The solution which Parth gave was correct. Its just that Cable Connected was disabled in the configuration.

Yes... my host os connection is working fine. NAT is also enabled. But still VM is not connected to network!
