Description

This article describes how to implement ZTNA TCP forwarding for public-facing servers.

Scope

FortiOS , FortiClient, Forticlient EMS

Solution

First, create a ZTNA destination on the EMS and apply the ZTNA destination profile to the correct Endpoint policy.

In this example, ZTNA TCP-forwarding will be applied to www.youtube.com.

Confirm if the new ZTNA destination is appearing for the user on the FortiClient:

The IP 10.235.0.1 is what will be provided by the FortiClient. This ensures that TCP forwarding is applied as expected on the endpoint.

Now, create a ZTNA server and Proxy policy on the FortiGate to authenticate traffic.

Create a FQDN address object on the FortiGate with www.youtube.com and use it in the Server field as above:

ZTNA tags can be applied to the policy as necessary as well:

Traffic will now be allowed by the proxy policy, and ZTNA will be applied when the user accesses YouTube on the endpoint.
