Hello @Arul Jothi ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand that you are using WAFV2 with CRS 3.2 for your Azure App Gateway but you see that there is a file upload/download restriction when the file size is greater than 750 MB. As per the documentation it is mentioned that if you use WAFV2 with CRS 3.2 for your Azure App Gateway you will have file upload limit up to 4 GB. And would like to know how to define this value in your existing WAF Policy for Application Gateway.
To define the "Max file upload size" to 4 GB in your existing WAF policy for Application gateway, you can follow the below steps:
- Go to the Application Gateway WAF policy in Azure Portal.
- Expand the settings pane and go to Policy Settings.
- In the Max file upload size (MB) option, change the value to 4000.
- Click Save. This will make your Max file upload size limit to 4 GB.
Kindly let us know if the above helps or you need further assistance on this issue.
