Is there any way run a query the on the Firewall Policy Rule Base to show only selected rules in the Rule Base, according to your criteria via R81.10 API? Can it come true on R81.10 API? The client want to achieve taget very like "Firewall Policy Query" on Smartdashboard, but he want to used via API. Criteria Values Examples: source:192.168.10.1 action:(drop) You can enter one text string, such as an object's name or IP address without delimiters. In this case, SmartDashboard shows records that contain the given criteria in all relevant fields, e.g. an IP address will be searched in Source, Destination and Install On fields of rules. One string examples: CP_default_Office_Mode_addresses_pool 192.168.10.1 http IP Addresses You can enter IPv4 address using dotted decimal or CIDR notation. Examples: 192.0.2.32 192.0.2.0/24 Off course, it do not need the same feature. Simple firewall policy query is OK. Such as we can search source and destination IP and show us match policy via API is OK. THX!
