Configure Palo Alto Networks VPN

Configure Palo Alto Networks VPN to use the Okta RADIUS Server agent.

Okta and Palo Alto Networks interoperate through either RADIUS or SAML 2.0. For each Palo Alto gateway, you can assign one or more authentication providers.

Each authentication profile maps to an authentication server, which can be RADIUS, TACAS+, LDAP, etc. Using RADIUS, Okta’s agent translates RADIUS authentication requests from the VPN into Okta API calls.

This page describes how to integrate using RADIUS integration for Palo Alto Network VPN when running PanOS versions older than 8.0. It does not describe how to integrate using Palo Alto Networks and SAML.

When running PanOS 8.0, 9.0 or later, use SAML for your integration:
