GlobalProtect MAC Address Filter?

[OMatlock]

Hello folks,

I am being asked if GlobalProtect could be locked down to only except a specific list of MAC addresses (our corporate laptops) only.  

I see information about Device Block list or HIP configuration.  I don't really want to specify a block list, but rather an allow list and block everything else. 

Is that possible?

We using PA 3020 with 7.1.15.

It would be along side...

also along side your existing authentication method.....

so... go daddy for tls profile, ldap or sso or local user or 2 factor auth plus device cert to only allow known devices.

your challenge will be to distribute certs...

can be done via Group policy..

Not via mac address but have you considered certifcates...

just generate a root CA on your palo and then use this to create device certificates...

Ok, gotcha. Thanks @MickBall

Would this be along side (separately) from the existing wildcard we use for our GlobalProtect Gateway SSL/TLS profile?

Or instead of?

As I am thinking...sounds like could be instead of.  Could use "local" certificates rather than one like GoDaddy that every device has a CA root cert for.
