RE: same-security-traffic permit intra-interface

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?
