This agent component is included when you install Horizon Agent. If the Blast Secure Gateway is not enabled, after the user selects a remote desktop or published application, the web browser on a client device makes a direct connection to the HTML Access Agent on TCP port 22443 on the remote desktop virtual machine or RDS host. If the Blast Secure Gateway is enabled, after the user selects a remote desktop or published application, the Blast Secure Gateway connects to the HTML Access Agent on TCP port 22443 on the remote desktop virtual machine or RDS host. The Blast Secure Gateway must be enabled on a Connection Server instance to allow this second connection to take place. In Figure 1, the All Network Ports diagram shows all the possible client connection types for Horizon Cloud Service on Microsoft Azure, and includes all. This is just so that Horizon user's don't have to enter https. In Figure 1, the All Network Ports diagram shows all the possible client connection types for Horizon Cloud Service on Microsoft Azure, and includes all display protocols. It is normal to allow TCP port 80 as well as TCP port 443. To make the initial connection, the web browser on a client device connects to a Connection Server instance on TCP port 443.Īfter the initial connection is made, the web browser on a client device connects to the Blast Secure Gateway on TCP port 8443. With Unified Access Gateway support access to Horizon from the Internet, everything can be done with just TCP 443. Firewall Rules for Client Browser Access Source HTTP connections are not allowed.īy default, when you install a Connection Server instance, the VMware Horizon View Connection Server (Blast-In) rule is enabled in the Windows Firewall and the firewall is configured to allow inbound traffic to TCP port 8443. VMware has released a new KB article (KB83574) that explains how to interpret the vSAN performance graphs and how to use this information to troubleshoot issues. The Horizon Client then forms a protocol session connection to a Horizon Agent running in a virtual desktop, RDSH server, or physical machine. Error: 'USB redirection is not available for this desktop' due to an Agent side corrupt certificate. The core components of Horizon include a VMware Horizon Client authenticating to a Connection Server, which brokers connections to virtual desktops and apps. To allow client web browsers to make connections to Connection Server instances, remote desktops, and published applications, your firewalls must allow inbound traffic on certain TCP ports. Horizon Client USB redirection fails with 'Unexpected certificate thumbprint algorithm SHA-512' (90330) outlines an enhancement in the algorithm used which can result in USB redirection failure when accessed with a legacy horizon client.
