Create a new IKE profile.
Select

and select
Add
.
Enter a
Name
for the new profile.
Specify the Diffie-Hellman (DH) Group for key exchange and the Authentication and Encryption algorithms.
Click
Add
in the corresponding sections (DH Group, Authentication, and Encryption) and select from the menus.
If you aren’t certain what the VPN peers support, add multiple groups or algorithms in the order of most-to-least secure; the peers negotiate the strongest supported group or algorithm to establish the tunnel.

PAN-OS 10.2.0 and later releases

Authentication—

(
PAN-OS 10.0.3 and later releases
)
non-auth
If you select an AES-GCM algorithm for encryption, you must select the Authentication setting
non-auth
or the commit will fail. The hash is automatically selected based on the DH Group selected. DH Group 19 and below uses
sha256
; DH Group 20 uses
sha384
.
Encryption—
(
PAN-OS 10.0.3 and later releases
)
aes-256-gcm
(requires IKEv2; DH Group should be set to
group20
)
(
PAN-OS 10.0.3 and later releases
)
aes-128-gcm
(requires IKEv2 and DH Group set to
group19
)
aes-256-cbc
aes-192-cbc
aes-128-cbc
3des
(
PAN-OS 10.1.0 and earlier releases
)
des
Choose the strongest authentication and encryption algorithms that the peer can support. For the authentication algorithm, use SHA-256 or higher (SHA-384 or higher preferred for long-lived transactions). Don’t use SHA-1 or MD5. For the encryption algorithm, use AES; DES and 3DES are weak and vulnerable. AES with Galois/Counter Mode (AES-GCM) provides the strongest security and has built-in authentication, so you must set Authentication to
non-auth
if you select
aes-256-gcm
or
aes-128-gcm
encryption.
Specify the duration for which the key is valid and the reauthentication interval.
For details, see SA Key Lifetime and Re-Authentication Interval.
In the
Key Lifetime
fields, specify the period (in seconds, minutes, hours, or days) for which the key is valid (range is 3 minutes to 365 days; default is 8 hours). When the key expires, the firewall renegotiates a new key. A lifetime is the period between each renegotiation.
For the
IKEv2 Authentication Multiple
, specify a value (range is 0-50; default is 0) that is multiplied by the
Key Lifetime
to determine the authentication count. The default value of zero disables the reauthentication feature.
Commit your IKE Crypto profile.
Click
OK
and click

Attach the IKE Crypto profile to the IKE Gateway configuration.
See Configure advanced options for the gateway.
