based on your preferences when you create a hierarchical global or regional network firewall policy cloud next generation firewall automatically adds predefined rules you can customize or override these rules to maintain your intended network security posture predefined rules vary depending on whether you use the google cloud console gcloud cli or api this document helps network administrators and security engineers define rules for firewall policies types of predefined rules if you create a firewall policy using the google cloud console cloud ngfw adds the following rules to the new policy goto next rules for private ipv4 ranges predefined google threat intelligence deny rules predefined geolocation deny rules lowest possible priority goto next rules if you create a firewall policy using the google cloud cli or the api cloud ngfw adds only the lowest possible priority goto next rules to the policy note these predefined rules in firewall policies are different from the implied and prepopulated vpc firewall rules all predefined rules in a new firewall policy purposefully use low priorities large priority numbers so you can override them by creating ingress or egress rules with higher priorities except for the lowest possible priority goto next rules you can also customize the predefined rules goto next rules for private ipv4 ranges an egress rule with destination ipv4 ranges 10 0 0 0 8 172 16 0 0 12 192 168 0 0 16 priority 1000 and goto_next action an ingress rule with source ipv4 ranges 10 0 0 0 8 172 16 0 0 12 192 168 0 0 16 priority 1001 and goto_next action
