#300 create a connection with ssh gateway / ProxyJump

[Lorenzo]

Hi,
I can't find the feature which allow me to connect to a ssh gateway trough proxyJump.
I need to connect to ssh at "server_gateway" and from here connect to a "final server".
In advanced option i select "ProxyCommand" with command "ssh user@server_gateway" but when i lunch the connection I'm not prompted for the password and the connection failed.
How can i resolve the problem?
Thanks in advance.
