Security Context Overview Chapter 4 Configuring Security Contexts static (inside,shared) 10.30.10.0 10.30.10.0 netmask 255.255.255.0 If you use dynamic NAT, an active NAT session is created when the real host creates a connection through the shared interface. For traffic returning to the host, the active NAT session is used to classify the packet. To quickly identify possible overlaps between different contexts, a situation that leads to connectivity problems, enter the show np 3 static command in the system execution space. Note For management traffic destined for an interface, the interface IP address is used for classification. Invalid Classifier Criteria The following configurations are not used for packet classification: • NAT exemption-The classifier does not use a NAT exemption configuration for classification purposes because NAT exemption does not identify the mapped (shared) interface. • Routing table-The classifier does not use the routing table for classification. For example, if a context includes a static route that points to an external router as the next-hop to a subnet, and a different context includes a static command for the same subnet, then the classifier uses the static command to classify packets destined for that subnet and ignores the static route.
