In this video, we introduce the step-by-step configuration guide for "VPN for Legacy Apps" in Zscaler Private Access (ZPA). Traditionally, ZPA provides high security by hiding the actual server IPs without building a traditional network. However, this posed a challenge for legacy applications—such as VoIP and Active FTP—that require communication using real IP addresses. By implementing "VPN for Legacy Apps," both ends of the communication can verify each other's actual IP addresses, solving compatibility issues for VoIP and other legacy protocols. --- Disclaimer: This video is a simplified guide created based on publicly available official documentation.
