Sanjay,
I'm in the middle of a class right now but check a couple of the docs
and you should find what you need. I've used the docs to set it up for an
internal lab I developed and it worked, although overlapping ip addresses
with nat is rather confusing. If I remember correctly there's one key
stumbling block that you can run into with the static route you need to
add (I believe it was a matter of what you point it to, it's not what you
think).
Let me know if you don't get it working and I can check after class, I can
send you that portion of the lab, which includes the working config.
