To work remotely I need to SSH into the main server and then again into the departmental server.

I would like to set up a tunnel using sublime text 3 wbond sftp package to view and edit files remotely but I can't seem to find any information for setting up a tunnel. Is this even possible?

The reason I'm interested in this particular package is because I am unable to install any packages locally on the server, hence using something like rsub is not possible.

Any other suggestions besides sublime sftp are welcome.

I'm not sure the SFTP plugin would allow to do this directly.
What i would suggest is for you to use ssh -L to create a tunnel.

ssh -L localhost:random_unused_port:target_server:22 username_for_middle_server@middle_server -nNT
Use the password/identity_file for the middle server

The -nNT is to avoid opening an interactive shell in the middle server.
IMPORTANT: You need to keep the ssh -L command running so keep that shell open.
In this way you can connect to the target_server as such:

ssh username_for_target_server@localhost -p random_port_you_allocated

Similarly you can setup the SFTP plugin file as such

{
    ...
    "host":"localhost",
    "user":"username_for_target_server",
    "ssh_key_file": "path_to_target_server_key",
    "port":"random_port_you_allocated",
    ....
}

As a sidenote, always use the same port to tunnel to the same server, otherwise, with the default ssh configuration, you will be warned of a "Man in the middle attack" because the signature saved in the .ssh/known_hosts will not match with the previous one. This can be avoided by disabling this feature but I wouldn't recommend it.
