Access Policy Manager® (APM®) can act as a gateway for Microsoft RDP clients, authorizing them on initial access and authorizing access to resources that they request after that. The APM configuration includes these elements.
Sample client authorization policy
Notice the RDG Policy Assign item; it is used to specify the resource authorization policy.

If you already have configured them, you can use existing configuration objects: a machine account, an NTLM authentication configuration, a VDI profile, a connectivity profile, and a client SSL profile.
Supported Microsoft RDP clients can use APM® as a gateway. The configuration supports Microsoft RDP clients on Windows, Mac, iOS, and Android.
Refer to BIG-IP® APM® Client Compatibility Matrix on the AskF5™ web site at http://support.f5.com/kb/en-us.html for the supported platforms and operating system versions for Microsoft RDP clients.
On a Microsoft RDP client, a user types in settings for a gateway and a connection. The names for the settings vary depending on the Microsoft RDP client.
Supported Microsoft RDP clients can specify a virtual server on the BIG-IP® system to use as a remote desktop gateway. Access Policy Manager® (APM®) can authorize the clients and authorize access to target servers as the clients request them.
If you configure Access Policy Manager® APM® as a gateway for RDP clients and configure APM to act as an explicit forward proxy on the same BIG-IP® system, you need to complete an additional configuration step to ensure that APM can process the RDP client traffic. The configuration F5 recommends for explicit forward proxy includes a catch-all virtual server, which listens on all IP addresses and all ports, on an HTTP tunnel interface.
When a programmatic API queries listeners for a specific IP and port, the query covers all interfaces and tunnels. As a result, the catch-all virtual server will always match. Sending traffic using this tunnel results in all packets being dropped because this virtual server is configured as a reject type of virtual server.
To prevent RDP client traffic from being dropped, add an additional wildcard port-specific virtual server on the HTTP tunnel interface.
In the recommended Secure Web Gateway explicit forward proxy configuration, client browsers point to a forward proxy server that establishes a tunnel for SSL traffic. Additional wildcard virtual servers listen on the HTTP tunnel interface. The listener that best matches the web traffic directed to the forward proxy server handles the traffic.
