Problem with usb tethering

Hello
I am facing problem with usb tethering which was working fine a while ago.
I am trying to connect my android phone via usb cable to use internet on pc from my mobile data.
My phone connected to my pc with usb tethering but there is no internet access in pc when I try to use my mobile network data. But when I first connected my phone to wifi broadband and then use my phone as a modem to connect to pc via usb tethering then it works fine means I have internet access .
Also I have internet access on my phone via mobile network.
But I want to use my mobile networks data for internet on pc .
There was no problem a while ago and I dont remember if I changed any settings on pc or phone.
so please help
 
Sorry for trouble guys cause I found a solution on my own.
I will not remove this therad so any one troubling with same problem will find it usefull
.so here is what I did
I had installed afWall (a firewall for phone) in my phone which is probably blocking my internet access.
so all I did was disable firewall on phone and restart phone and now I am able to use internet on pc via usb tethering while using data from my mobile network.
