What is an SSH Tunnel?
The SSH2 protocol allows for something called “port forwarding”…more commonly known as “SSH Tunneling”. Normally (i.e. using an SSH2 client that is not Safe Passage) a user is required to manually specify a localhost port (a TCP/IP port on the user’s computer) that the SSH2 client should listen on. When the SSH2 client receives traffic on that local port, it sends that traffic via the user-configured port forward to the SSH2 server. The server then sends the traffic to a destination host that the user provided during configuration. It’s a real pain. Safe Passage dynamically automates all of the SSH port forward configuration, so all you need to specify is your SSH2 host address, login information, and optionally modify Advanced tunnel settings. It’s really easy.
