could not connect internet from vmplayer ubuntu

Hi,

I installed vm player 5.0 in my windows 7 laptop.

I also install Ubuntu 13.0 using vmplayer.

But the issue is, I could not connect internet though Ubuntu.

I can ping Ubuntu from Host machine(win 7). But the reverse is not happening.

I also tried all possible conditions by changing Network type(NAT, Bridged etc). But nothing works out.

I think something in win 7  is blocking all the request.

Any suggestion ?

Thanks,
