Hi,I am trying to make a dns spoofing for example on facebook.com

I have set the apache server and i have followed all the common instructions in common instructions for spoofing.
In terminal it says that the page is spoofed but in browser there is no fake page or redirection.I don't know what's going wrong.I have devoted many hours searching and i don't know any solution to this problem.
I am running backtrack in virtual machine.Below is what i get.The IP (172.16....) is the ip on the virtual machine.
