No, it's able to use your local ssh_config. For example, I use this to connect to a host running on aws via ssm. The vm isn't reachable at all directly.

You can use something like the following in your ~/.ssh/config:

    Host devhost
        ProxyCommand        aws --profile DevProfile ssm start-session --target i-0123456789abcdef0 --document-name AWS-StartSSHSession --parameters "portNumber=22"

You then tell intellij to connect to "devhost". This also works under recent versions of Windows (those which ship with openssh).

ipv6 is perfect for this use case, every development VM is directly reachable.
