For using this on Debian & similar distros:

ssh-keygen -t ed25519 && apt install autossh

Copy the SSH key to the remote server, eg: ssh-copy-id user@remoteserver
Create this file at /etc/systemd/system/autossh-jump-rtunnel.service and update line 7 from user@remoteserver to the correct user & server

systemctl enable autossh-jump-rtunnel.service
systemctl start autossh-jump-rtunnel.service
