What’s New in v4.0 MR3 : Firewall Policies Consistency Check
 
Firewall Policies Consistency Check
FortiManager v4.0 MR3 adds the ability to check all firewall rules and policies to ensure consistency and eliminate rule conflicts that may prevent your devices from passing traffic. The check will verify:
Object duplication: two objects that have identical definitions
Object shadowing: one object completely shadows another object of the same type
Object overlap: one object partially overlaps another object of the same type
Object orphaning: an object has been defined but has not been used anywhere.
This will allow you to optimize your rule and policy sets and potentially reduce the size of your databases.
