Redirecting Packets

I have a fairly simple task that I cant seem to find the answer to. I need
to write a device driver that redirects all TCP traffic to another address
and port. For instance, in IE, I go to www.yahoo.com, I would like to grab
that and redirect the request to www.google.com. So it works like a proxy
but I need it at the device driver level. Basically I need to forward all
web traffic to a specific address.

I have looked at the passthrough and stream inspection samples in the
WinDDK, but I am just not able to comprehend whats going on in there. I am a
C# guy but I am getting the feeling thats not going to help in this case. If
anyone has some sample code that does this, it would be a life saver.

Thanks,
Ray
