The server to which I'm trying to connect uses a whitelist of IP addresses. When I'm not on a whitelisted IP I connect with the terminal via a login server, called "doornode". After logging in to the doornode I get a interactive menu to choose which server I want to connect to, and after choosing I'm automatically redirected (I have to authenticate again). Obviously this doesn't work with WinSCP, so I can only connect with the terminal which makes exchanging files a hassle. Is there a way to setup a session which allows me to do file exchange? It tried the tunneling approach described here: https://winscp.net/eng/docs/guide_tunnel, but that didn't work. When trying to connect through the tunnel the target server still seems to reject me.
Thanks & cheers,
