EnumPolicyXFFOrder

• FIRST - Use first IP address in X-Forwarded-For header
• SECOND - Use second IP address in X-Forwarded-For header
• THIRD - Use third IP address in X-Forwarded-For header
• FOURTH - Use fourth IP address in X-Forwarded-For header

X-Forwarded-For: client-ip, proxy1-ip, proxy2-ip

The xffOrder determines which IP address is used:

• FIRST - Uses client-ip (original client)
• LAST - Uses proxy2-ip (last proxy)
• SECOND, THIRD, etc. - Uses IP at specified position

    }
  }'

​

Example 3: Save and Deploy

curl -X PATCH \

Notes and Warnings

• Header Name: Default is X-Forwarded-For. Can be customized (e.g., X-Real-IP)
• IP Order: FIRST gets original client IP, LAST gets last proxy IP
• Use Cases:
  • Forward client IP for logging/analytics
  • Forward client IP for rate limiting
  • Forward client IP for geolocation
• Chain: X-Forwarded-For contains comma-separated IP chain
• Deploy: When deploy=true, the API proxy is automatically deployed to the specified environments after saving
