All:

Look where he learned the route from:

> A Net 12-12 [1/G] via 0.0, 981 sec, Tunnel0, zone 12ether

He learned it via an AURP tunnel! You cannot ping through an AURP tunnel
interface if you are the source or the destination of the tunnel (my
experience). Change your source Appletalk address to something on the
ethernet segment and you should have no problems with Appletalk ping.
