Define a network zone for IWA

When evaluating Integrated Windows Authentication (IWA) sign-ins, Okta checks that the sign in is from the configured zones. When an IWA agent is configured, the IP address of the client is added to the LegacyIPZone. The LegacyIPZone is the only zone configured by default. You can define up to 20 dynamic zones s in IWA Network Zones.

LegacyIPZones can't be deleted.

Before you begin

Ensure that IWA Web agent is installed and configured. See Install the Okta IWA Web agent.
