Reverse Proxy Using ARR

Hi experts,

I have reverse proxy in the environment where it has existing server farm pointing to the exchange backend services for OWA and autodiscover. However, I would like to use the same reverse proxy server to translate SFTP port from inbound to outbound. Basically it is something as below:-

1. User request for sftp://public_IP:6782, then it translates to the backend server which is sftp://private_IP:22

Can we configure such a thing in reverse proxy via IIS ARR?
