Connect to SFTP through Proxy

Hi everyone, 

I need to connect to an SFTP server from InterSystems IRIS 2024, but the connection must go through a proxy. 

I couldn’t find any built-in support for SFTP with proxy in IRIS/Ensemble. 

What would be the recommended approach in this case? 

is there any native or supported way to handle SFTP + proxy? 

Any examples or best practices would be appreciated. Thanks!
