Yes, exemption would be the choice. I had meant using identity just to
confirm he could get the intra-interface working.

Wouldn't Nat exemption work better instead of identity Nat?

Tim,
 
The NAT config you have defined will only affect traffic going
inter-interface (inside-outside). The issue is that you have enabled nat
for
all inside to translate to outside. You don't list the contents of your
acl,
but no matter what since you have defined nat for all interior paths (0
0),
you most likely are dropping your intra-interface traffic. One
possibility
is to use identity nat for the intra-interface traffic and that should
fix
your issue.

        I am having trouble hairpinning to several private networks
behing
ethernet 1
        (security 100) on a PIX515E-UR running 8.0 code.
        
        I have enabled same-security-traffic permit intra-interface,
nat-control is
        off and I have tried several versions of NAT including:
        
        nat (inside ) 1 0.0.0.0 0.0.0.0
        Global (outside) 1 interface
        
        nat (inside) 2 access-list xxx
        glocal (inside) 2 interface
        
        Any ideas?
