Watch a video about Adding Locations
The following information describes how to add a single location. If you have multiple locations, you can import a CSV file that lists your locations and sub-locations. To learn more, see Configuring Multiple Locations and Sub-Locations.
To add a location:
- Go to Administration > Locations.
- Click Add Location.
The Add Location window appears.
- In the Add Location window, in the Location section:
- Name: Enter a name for the location
- Country: Choose your location's country
- State/Province: Enter the location's state or province, if applicable
- Time Zone: Choose the time zone for the location
When you specify the location in a policy, the service applies the policy according to the location's time zone. For example, if a Cloud App Control policy blocks posting to Facebook between 8 AM and 5 PM., and the rule is applied to locations in Spain and California, users at each location will be blocked during their respective daytime hours.
- In the Addressing section:
- In the Gateway Options section:
- Enable XFF Forwarding: Enable this option if this location uses proxy chaining to forward traffic to the Zscaler service, and you want the service to use the X-Forwarded-For (XFF) headers that your on-premise proxy server inserts in outbound HTTP requests. The XFF header identifies the client IP address, which can be leveraged by the service to identify the client’s sub-location.
Using the XFF headers, the service can apply the appropriate sub-location policy to the transaction, and if Enable IP Surrogate is turned on for the location or sub-location, the appropriate user policy is applied to the transaction. When the service forwards the traffic to its destination, it will remove thr original XFF header and replace it with an XFF header that contains the IP address of the client gateway (the organization’s public IP address), ensuring that an organization's internal IP addresses are never exposed to externally.
- Enforce Authentication: Enable to require users from this location to authenticate to the service. To learn more, see Provisioning and Authenticating Users.
- Enable IP Surrogate: If you enabled Enforce Authentication, select if you want to map users to device IP addresses. To learn more, see What is Surrogate IP? If you enable this feature:
- In Idle time to Disassociation, specify how long after a completed transaction the service retains the IP address to user mapping.
- If you want to use existing IP-to-user mapping (acquired from the surrogate IP) to authenticate users sending traffic from known browsers, enable Enforce Surrogate IP for Known Browsers.
With this feature enabled, the Zscaler service uses existing IP-to-user mapping for authentication even if users go to sites that support cookies. This allows the service to authenticate without requiring the browser to complete HTTP redirects for every transaction, ensuring performance even for users who connect, for example, over high-latency satellite links. If the feature is disabled, the service authenticates users on browsers with cookies or other configured authentication mechanisms.
- If you enabled Enforce Surrogate IP for Known Browsers, in Refresh Time for re-validation of Surrogacy, specify the length of time that the Zscaler service can use IP-to-user mapping for authenticating users sending traffic from known browsers. After the defined period of time elapses, the service will refresh and revalidate the existing IP-to-user mapping so that it can continue to use the mapping for authenticating users on browsers.
Refresh time for the revalidation of IP surrogacy must be smaller than the DHCP lease time. Otherwise the wrong user policies might be applied.
- Enable SSL Scanning: Select to enable the service to decrypt HTTPS transactions and inspect them for data leakage, malicious content and viruses, and to enforce policy.
- Enforce Firewall Control: Select to enable the service's firewall controls.
- In the Bandwidth Control section, you can Enforce Bandwidth Control for the location. If enabled, specify the maximum bandwidth limits for Download (Mbps) and Upload (Mbps).
- Click Save and activate the change.
