I did a forwarding policy in order to solve the SFTP issue which is not supported by default by the proxySG.
To make it short now user is able to connect on by executing the following command :

sftp -P 8088 exampleuser@proxyname

The server executing this command will automatically forwarded to

My question is how can we add proxy authentication in this process ? I mean if we have two authentication :

- proxy authentication
- authentication

I am not asking how to setup on the proxy itself but on the server instead... because here the user is directly forwarded to, if we use the proxyID then the same username will be used for autotmatically which are totally different account. I am having difficulties because proxy is used as "destination" in order to access to so there is no "intermediate proxy" in the command that can be added.
Unless proxy authentication is not planned to be used for this type of configuration ?

Thanks in advance for your help

Hello Furil,
you can't authenticate at the proxy with a simple forwarding.

You'd need to do either SOCKs protocol or you just tunnel this traffic within https. With this you can simply do authentication as with normal traffic.

Hope that helps somehow,
