IPSec Version

For audit purposes we neeed to know if paloalto is using IPSec version 3 or version 2?


Hi @Chana88 ,


Version of what? IPsec is not single protocol, but suite of different protocols working together. So there is no such think as IPsec version 2 or 3, to my knowledge.


Can you provide the exact question defined by the auditor?

In addition the answer to this question will really depend on your configuration, as FW can support almost any type of configuration.


Hi @aleksandar.astardzhiev  Thanks for the reply. My understanding was same as yours. 


However as per below RFC 2411 we have versions for IPSec. Auditors wanna know which version PA use. 






The PANW will be using IPSec v3.
