Is it possible to log into a server using an FTP client (e.g. Cyberduck) through a VPS, i.e. doing a double-hop to access a server?
Here's what I'm trying to do: my home computer is a mac, and my normal S/FTP client is Cyberduck. I have an Ubuntu VPS through DigitalOcean. The server I wish to connect to only allows connections from the IP (IPv6) of my VPS. Therefore, I want to connect to the server using Cyberduck (or another GUI-based Mac FTP client) via the VPS. I have public keys set up to connect without passphrase to the VPS, and need to use a passphrase to connect to the server from the VPS.
Am I wanting to set up a tunnel? Or a proxy? Or what?
The answer provided at SFTP over double server hop only gives answers for command-line or Windows. I'm looking for a GUI solution on the Mac.
