In this example, a TCP forwarding access proxy (TFAP) is configured to demonstrate an HTTPS reverse proxy that forwards TCP traffic to the designated resource. The access proxy tunnels TCP traffic between the client and the FortiGate over HTTPS, and forwards the TCP traffic to the protected resource. It verifies user identity, device identity, and trust context, before granting access to the protected source.
By default, encryption is disabled on FortiClient ZTNA rules, as this reduces overhead for end to end protocols that are already secure. For insecure end to end protocols, enable encryption.
RDP access is configured to one server, and SSH access to the other.
This example assumes that the FortiGate EMS fabric connector is already successfully connected.

The mapped port (
mappedport) restricts the mapping to the specified port or port range. If
mappedport is not specified, then any port will be matched.
