Enable the following debugs:

on the router:

debug crypto isakmp

debug crypto ipsec

on the ASA:

debug crypto condition peer x.x.x.x (address of the router)

debug crypto isakmp 20

debug crypto ipsec 20

Then generate some interesting traffic, and check the resulting debugs (or post them here).
