Your OS X client is initiating the RPC request to your NetBSD server;
this works. But the NetBSD server has to issue RPC requests to your
OS X client (to contact statd), and I can't see how this one could
work if there's a NAT gateway between the server and the client.

I'm not sure, as the lock requests are independant from NFS.
