Configure F5 BigIP APM to interoperate with Okta via RADIUS

This guide details how to configure F5 BIG IP APM to use the Okta RADIUS Server Agent in conjunction with the Okta Integration Network (OIN) F5 BIG IP RADIUS for APM and VPN App.

Note

To integrate with Okta via SAML 2.0, add the F5 BIG IP SAML for APM and VPN SAML app in Okta by:

Navigating to the Applications tab.
Selecting Applications > Add Application.
Searching for F5 BIG IP SAML for APM and VPN.
And then click Add.

Before you begin

Before installing the Okta RADIUS Agent ensure that you have met these minimum requirements for network connectivity:

Source	Destination	Port/Protocol	Description
Okta RADIUS Agent	Okta Identity Cloud	TCP/443 HTTP	Configuration and authentication traffic
Client Gateway	Okta RADIUS Agent	UDP/1812 RADIUS (Default, may be changed in RADIUS app install and configuration)	RADIUS traffic between the gateway (client) and the RADIUS Agent (server)

Supported factors

The following MFA Factors are supported:

When integrating with Okta RADIUS, the maximum supported number of enrolled factors is dependent on the size of resulting challenge message. Okta recommends that no more than eight ( 8 ) factor be enrolled at one time.

Custom TOTP Authentication	Supported	Supported	Supported
Duo(Push, SMS and Passcode only)	Supported	Not supported	Not supported
Email	Supported	Supported	Not supported
Google Authenticator	Supported	Supported	Supported - as long as challenge is avoided. For example MFA only or password, MFA.
Okta Verify (TOTP and PUSH)	Supported	Supported	Supported - as long as challenge is avoided. For example: MFA-only or password, MFA for TOTP. Push can work with primary auth + MFA as the push challenge is sent out-of-band.
