Cisco ASA 5500 Series Configuration Guide using ASDM
Chapter 64 Configuring the ASA CSC Module
Licensing Requirements for the CSC SSM
In the outside-policy, outside-class matches SMTP traffic from any outside source to the DMZ network.
This setting protects the SMTP server and inside users who download e-mail from the SMTP server on
the DMZ network, without having to scan connections from SMTP clients to the server.
If the web server on the DMZ network receives files uploaded by HTTP from external hosts, you can add
a rule to the outside policy that matches HTTP traffic from any source to the DMZ network. Because the
policy is applied to the outside interface, the rule would only match connections from HTTP clients
outside the ASA.
