Configuring traffic redirection to a Web Security Gateway
The purpose of this Use Case, which is complementary to "Use Case 1", is to enable the connection to a Zscaler Web Security Gateway delivered from the cloud. The Zscaler platform defends against malware, advanced threats, phishing, browser exploits, malicious URLs and botnets. As well as web security, the service offers web filtering, firewalls and anti-spam functions.
This section describes how to configure this gateway in your network, from Branch Office 1 appliance over the Internet.
One tunnel is created after you have defined the appropriate parameters in both the Orchestrator and in Zscaler.
Note: Only Zscaler is supported in this SD-WAN Orchestrator version. It is likely that other web security gateways can be defined.

On the displayed window, click the Add button to display the form. The basic procedure for defining a web security gateway consists of the following steps:
| • | Identifying the gateway |
| • | Defining the Public IP addresses of both the Zscaler Gateway and the Branch Office appliance it is connected to. The Public IP addresses of the Zscaler security gateway include a primary address and a secondary backup address used to set up two tunnels in active/backup configuration. |
| • | Defining the IPSec tunnel parameters. |
Refer to the following sections for detailed explanations.
