Unfortunately it doesn't work if you're behind a NAT due to shitty ISP, like me. I use AutoSSH instead to expose my local machine's ssh port on a high port in the gateway machine: `autossh -M 0 -o "ServerAliveInterval 30" -o "ServerAliveCountMax 3" -v -N -R 22222:localhost:22 user@my-vps-domain`

ServerAliveInterval 30 is important because my ISP often drop idle connections, often not even 1 minute idle. Can probably tweak it to listen to a localhost only port instead of exposing them to internet.
