[c-nsp] Issues with traffic flow through a FWSM

Hello,  we are trying to set up a new network.  We are trying to tie
several switches to a Cat6506 with the FWSM integrated.  We have the
switches going into the FWSM.  The outside interface is the MSFC of
the 6506.
 From there it goes to the outside world.  We are running OSPF between
everything.  All of the switches sees the networks of the other
switches.  The problem is that none of the switches can ping or pass
other traffic to the other switches.
The FWSM can only ping IPs off the MSFC card.  Those IPS can also ping
the FWSM but nothing else.  I do not need NAT (did a no nat-control).
Here are the config snipets.  What am I missing?  Thanks in advance
for the help.
