Please review and share us with your thoughts. Awaiting for your reply !!

@SahulH,

Not via MAC address. You would do this by creating an entry within the Device Block List and specifying the Host ID and Hostname of the blocked endpoint.

Hi @BPry ,

Thanks for your response. How do I get the Host ID information from a Machine to configure the Device Block List.

Also one more query is that, do we need to a have any specific subscription for using Device Block List feature in PA Firewall.

@SahulH,

The Host ID field is visible in the GlobalProtect logs (I don't know if this is a default field, so you may have to view detailed logs or simply select it so it's visible). You don't need a GlobalProtect subscription to have the ability to use this feature.

@BPry ,

Under Global Protect Logs we are unable to get the Host-ID information for Linux based machines. So is this related to Licensing. Since we don't have a valid subscription for GP gateway. Please share your thoughts.

@SahulH,

If you don't have a GlobalProtect subscription then your Linux agents are using X-Auth instead of the actual GlobalProtect agent. In that case, a Host ID isn't generated and you don't have a clear cut way to block any one particular endpoint.

@BPry ,

Query 1 --> Whether can we able to see the logs for the user machine which we have blocked using the Host-ID in case if they try to connect to the Global Protect?.

Query 2 --> Also in Global Protect logs, for some of the MAC and Windows machine Host-ID information is not captured by the Agent what will be the possible cause for this and how to resolve this .

Snap for Host ID not captured for some and captured for some for the same machine itself:

Please let us know if you have thoughts on this below mentioned queries. Awaiting for your response !!
