Microsoft RemoteApp G.W in Server 2012 R2

Good Day Experts,

 

I have installed Server 2012 R2 with RemoteApp Server. I have 20 RDS CALS and Configured Remote G.W.

 

My Question is that now i have an other Virtual Server and i want to use this New VM Resources.

 

Can you please advise me on it ? How the other users can connect the RemoteApp using New VM Resources  or what it called ? 

 

Regards,
