The following is sample output from the show policy-firewall config command to validate a configured zone based firewall. The secret killer of VA solution value is the false positive. since rule sets use a common action (such as inspect, drop, or pass), a variety of rules are added to one class-map with multiple If there is anoutside interface with a static IP address, note that interface name and complete the next procedure. The interface must have, at a minimum, an IP address configured, and it must be working. Step3 In the traffic selection panel select a From interface and a To interface to specify the traffic flow to which the firewall has been applied, and click Go.
