Table 53. Default Ports (Continued)
Protocol Port
PCoIP Any TCP port from Horizon Client to port 4172 of the remote desktop or application.
PCoIP also uses UDP port 50002 from Horizon Client (or UDP port 55000 from the PCoIP Secure
Gateway) to port 4172 of the remote desktop or application.
PCoIP or RDP For USB redirection, TCP port 32111 is used alongside PCoIP or RDP from the client to the remote
desktop.
TCP Ports for View Connection Server Intercommunication
View Connection Server instances in a group use additional TCP ports to communicate with each other. For
example, View Connection Server instances use port 4100 to transmit JMS inter-router (JMSIR) traffic to each
other. Firewalls are generally not used between the View Connection Server instances in a group.
View Broker and Administration Server
The View Broker component, which is the core of View Connection Server, is responsible for all user
interaction between clients and View Connection Server. View Broker also includes the Administration
Server that is used by the View Administrator Web interface.
View Broker works closely with vCenter Server to provide advanced management of remote desktops,
including virtual machine creation and power operations.
View Secure Gateway Server
View Secure Gateway Server is the server-side component for the secure HTTPS connection between client
systems and a security server or View Connection Server instance.
When you configure the tunnel connection for View Connection Server, RDP, USB, and Multimedia
Redirection (MMR) traffic is tunneled through the View Secure Gateway component. When you configure
direct client connections, these protocols connect directly from the client to the remote desktop and are not
tunneled through the View Secure Gateway Server component.
NOTE Clients that use the PCoIP display protocol can use the tunnel connection for USB redirection and
multimedia redirection (MMR) acceleration, but for all other data, PCoIP uses the PCoIP Secure Gateway on
a security server.
View Secure Gateway Server is also responsible for forwarding other Web traffic, including user
authentication and desktop and application selection traffic, from clients to the View Broker component.
View Secure Gateway Server also passes View Administrator client Web traffic to the Administration Server
component.
PCoIP Secure Gateway
Security servers include a PCoIP Secure Gateway component. When the PCoIP Secure Gateway is enabled,
after authentication, clients that use PCoIP can make another secure connection to a security server. This
connection allows clients to access remote desktops and applications from the Internet.
When you enable the PCoIP Secure Gateway component, PCoIP traffic is forwarded by a security server to
remote desktops and applications. If clients that use PCoIP also use the USB redirection feature or
multimedia redirection (MMR) acceleration, you can enable the View Secure Gateway component in order
to forward that data.
When you configure direct client connections, PCoIP traffic and other traffic goes directly from a client to a
remote desktop or application.
