How do I configure firewall policies?

Perform the following tasks to configure firewall policies:

  1. Configure the resources that the policies will reference:
  2. Define the rules for each policy:
  3. By default, the Zscaler service "listens to" port 80 for HTTP traffic, port 443 for HTTPS traffic, port 53 for DNS traffic, and port 21 for FTP traffic. If your organization uses other ports or additional ports for HTTP, HTTPS,  DNS, or FTP traffic, you can configure the service to use custom ports for these services.
  4. Enable the firewall per location.
