A. Cisco IOS software-based NAT is not fundamentally different from the NAT function in the Cisco PIX Security Appliance. The main differences include the different traffic types supported in the implementations. Refer to Cisco PIX 500 Series Security Appliances and NAT Configuration Examples for more information on the configuration of NAT on Cisco PIX devices (includes the traffic types supported).
