    SSH reverse tunnel using autossh

    (Alternate title: How to access servers behind firewalls)

    Often times we can access a remote computer over the internet by using port-forwarding on the router. This is accomplished by forwarding / DNAT a port say 22, or 80 or 443 from the router to the server inside that network. Usually this is done for computers and servers running inside a home network. What if the router does not have port forwarding options? What if the internet service provider does not allow traffic to come to the public interface of their router, even if the router has port-forwarding / DNAT options available? In such a case, you would need to use a reverse SSH tunnel. This article helps understand and setup such a tunnel.
