Modify GlobalProtect Device Block List via API

TLepingwell-ctr — Wed, 12 Apr 2023 17:31:37 GMT

I am trying to automate blocking GlobalProtect clients via API calls. Our firewall is running PanOS 9.1.15-h1 and is controlled by a onsite Panorama instance on 10.1.8-h2. Due to the version mismatch GlobalProtect device blocks must be implemented directly on the firewall because the blocking mechanism for GlobalProtect clients changed between PanOS 9 and 10.

I know that it is possible to disconnect a GlobalProtect session via the API, but if the device is not blocked they can just reconnect.

Where I am stuck is finding an API call that corresponds to the Network -> GlobalProtect -> Device Block List category in PanOS 9. I have the suspicion that this functionality might not be exposed by the API in this version of PanOS, but I wanted to ask to see if anyone has had success with this or can confirm that the functionality is not exposed.

Hi @TLepingwell-ctr,

If there is no block list already, the XML API call to create the list with a host in the list is:

https://{{host}}/api?type=op&cmd=<request><device-block-list><create><list>{{list-name}}</list><devices><member>{{host-id}};{{host-name}}</member></devices></create></device-block-list></request>&key={{key}}

You can add multiple <member></member> blocks for each host.

If you already have a list created (there can only be one list per VSYS I believe), then you want the update XML API call instead of the create XML API call:

You can add multiple <member></member> blocks for each host like the previous API call. Note that this call will replace the current list of hosts with the hosts listed in <member> blocks. If you wish to add a host, you likely need to get the current list:

https://{{host}}/api?type=op&cmd=<request><device-block-list><show><all/></show></device-block-list></request>&key={{key}}

...then add the new host to the list in the response, then send the newly updated list back.

Hope this helps

Thanks. That was exactly what I was looking for.
