Timothy, I don't think you will be able to form a neighbor relationship through the tunnel with that configuration. What I would do is put the tunnel interface on both sides in the same network rather than using unnumbered. Also, you would need to add the tunnel network into the OSPF process in order to form an adjacency and pass routes.
