What problem are you trying to solve?

Focus on the what and why of the need you have, not the how you'd like it solved.

To be able to access a MongoDB instance behind a proxy tunneled SSH, for example gcloud IAP proxy.

Vanilla SSH can do this via ProxyCommand:
ProxyCommand gcloud compute start-iap-tunnel --project <project> --zone <zone> '%h' '%p' --listen-on-stdin --verbosity=warning in the SSH config or command line. (That's what gcloud compute ssh --tunnel-through-iap does behind the scenes)

And the host and port come from the Host stanza in the SSH config.

What would you like to see happen?

Describe the desired outcome or enhancement.

For Compass to support this without requiring me to manually forward SSH ports.

Either for compass to support specifying ProxyCommand and ProxyUseFdpass directly or be able to read them from the SSH config

Why is this important to you or your team?

Explain how the request adds value or solves a business need.

So I don't have to instruct team members to manually forward SSH ports when connecting with Compass or to open the SSH port to the public

What steps, if any, are you taking today to manage this problem?

Manually forwarding SSH ports in the terminal before trying to connect with compass
