[Click] Can't understand what's wrong here!

Hi All,
 I am trying to send nfs reply packets to the fake network address
102.0.0.1 and rewriting the IPHeader to the original host. The exports
file has a nentry for the host 102.0.0.1, and since the packet doesn't get
changed , it should look like the root on 102.0.0.1 has sent the nfs
requests and since he has permission nfs should reply, but I don't see any
reply packets that are grabbed by fromhost, this could only mean that the
packets are getting dropped somewhere, I don't exactly understand where.
Any ideas, explanation of what I am doing worng.

Thanks.
