Hello Guys,
i bet the solution you are looking for is here:
"Generic Data Center feature" sk167210
The Generic Data Center feature provides the ability to enforce access to/from IP addresses defined in JSON files located in external web servers or locally on the Security Management machine. The Generic Data Center objects are updated automatically on the Security Gateway each time the JSON file change. There is no need to install policy for the updates to take effect. Objects created based on these files can be used as a source, or a destination in the following policies: Access Control policy, NAT policy, Threat Prevention policy, HTTPS Inspection policy.
best regards
Thomas
