The Blast Secure Gateway includes Blast Extreme Adaptive Transport (BEAT) networking, which
dynamically adjusts to network conditions such as varying speeds and packet loss.
n Blast Secure Gateway supports BEAT networking only when running on a Unified Access
Gateway appliance.
n Horizon Clients using IPv4 and Horizon Clients using IPv6 can be handled concurrently on TCP
port 8443 and on UDP port 8443 (for BEAT) when connecting to a Unified Access Gateway
appliance version 3.3 or later.
n Horizon Clients that use a typical network condition must connect to a Connection Server
(BSG disabled), security server (BSG disabled), or versions later than 2.8 of an Unified
Access Gateway appliance. If Horizon Client uses a typical network condition to connect to
a Connection Server (BSG enabled), security server (BSG enabled), or versions earlier than 2.8
of an Unified Access Gateway appliance, the client automatically senses the network condition
and falls back to TCP networking.
n Horizon Clients that use a poor network condition must connect to version 2.9 or later of an
Unified Access Gateway appliance (with UDP Tunnel Server Enabled). If Horizon Client uses
a poor network condition to connect to the Connection Server (BSG enabled), security server
(BSG enabled), or versions earlier than 2.8 of an
Unified Access Gateway appliance, the client
automatically senses the network condition and falls back to TCP networking.
n Horizon Clients that use a poor network condition to connect to Connection Server (BSG
disabled), security server (BSG disabled), or version 2.9 or later of Unified Access Gateway
appliance (without UDP Tunnel Server Enabled), or version 2.8 of Unified Access Gateway
appliance, the client automatically senses the network condition and falls back to the typical
network condition.

VMware-Horizon-Client/index.html.
Note You can also use Unified Access Gateway appliances, rather than security servers, for
secure external access to Horizon 7 servers and desktops. If you use Unified Access Gateway
appliances, you must disable the secure gateways on Connection Server instances and enable
these gateways on the Unified Access Gateway appliances. For more information, see
Deploying
and Configuring Unified Access Gateway
.
When the Blast Secure Gateway is not enabled, client devices and client Web browsers use
the VMware Blast Extreme protocol to establish direct connections to remote desktop virtual
machines and applications, bypassing the Blast Secure Gateway.
Important A typical network configuration that provides secure connections for external users
includes a security server. To enable or disable the Blast Secure Gateway on a security server, you
must edit the Connection Server instance that is paired with the security server. If external users
connect directly to a Connection Server host, you enable or disable the Blast Secure Gateway by
editing that Connection Server instance.
