Hi,
Please confirm:
- you are using the In-app SFTP connector
- Settings -- Network -- Virtual network integration -- under Application routing you have Outbound internet traffic selected
- Settings -- Network -- Virtual network integration -- under Virtual network routing you have your NAT gateway selected
The In-app SFTP connector runs in the single-tenant environment (yours) whereas the shared/managed SFTP connector runs in the multi-tenant environment.
With the above configuration the public IP of your NAT gateway should be used when connecting to the SFTP server.
