OK, I just ran the same experiment. 'tcpdump port nfs' running on both machines, and ipmon running on the ipnat-enabled NFS client. All logs from tcpdump and ipmon were totally empty. The packet(s) seem to just completely disappear, and the 'ls /home/paul' command just hangs waiting for netio.
Funny thing, though, is that there are never any "nfs server blah is not responding" console messages which is usually what you get when the client doesn't receive a response from the NFS server. It almost seems as though the NFS client hasn't even delivered the packet to the IP stack (ie, the send() hasn't completed so it's not even waiting for a recv()).
