After opening this port in the firewalls the problem was solved. So I discovered that the 4172 UDP protocol from the View desktop pool to the Security server was blocked by a firewall. The text typed in the screen must be displayed on both sides, If not the port is blocked. On the security server run Netcat to connect to the View Desktop on UDP port 4172: nc –u ipaddress 4172 On the View desktop run Netcat to listen to UDP port 4172: nc –l –u –p 4172 So I used Netcat to check the TCP and UDP ports between the Security server and View Desktop (1) and the View Desktop to the Security Server(2). With Netcat TCP and UDP ports can be checked (Telnet can only check TCP ports). To troubleshoot this problem I used the tool “Netcat”. I suspected that a PCoIP port (4172 TCP and UDP) is blocked between the Security Server and desktop pool or vice versa. When the users connects to the View Desktop using the LAN (without the Security Server) everything worked fine. The connection to the remote computer ended When a external View Client tried to connect through the Security Server using the PCoIP protocol to the View desktop the following appeared: In a new VMware View environment the customer has installed a VMware Horizon View Security Server for the external connections.

I’ve also taken the opportunity to separate tunneled (E.g. Many new components are present such as Blast on Linux virtual desktops, the new JMS enhanced security mode (JMS SSL), App Volumes and RDS hosts just to name a few. For 3 years now I’ve been maintaining a diagram detailing all of the network ports used by VMware Horizon (formerly View), and I am pleased to share the third version for the latest release. With the recent release of VMware Horizon 6.1.1 (June 2015) come many new features and changes. VMware Horizon 6.1.1 Network Ports Diagram
