I am not sure I completely understand what you are attempting to
communicate (and whether your second attempt to communicate is
complete). But one part of the symptom you describe is fairly
clear: your route on 7206 sends 216.10.32.0 to the 3640. The
3640 does not show a route for that network but does have a
default route which sends it back to the 7206. So you have created
a loop.

I am puzzled because your description implies that it does work when
you have the route pointed at the interface FA0/0. I dont see how this
does not form the loop, unless there is something you have not included.
