Systemd service to run autossh

If you have some devices behind a firewall or NAT (like most home networks) but want to access it from the outside you can use the autossh tool to continually expose their local sshd to a server running on the public internet. 

# /etc/systemd/services/autossh-sshd.service

[Unit]
Description=Exposes the local sshd through an ssh tunnel
After=network.target

[Service]
User=xxx
ExecStart=/usr/bin/autossh -N -T -R localhost:62000:localhost:22 user@yourserver.tld

[Install]
WantedBy=multi-user.target
