What is localhost port forwarding?

Use local port forwarding to forward data securely from an application client running on the same computer as the Secure Shell client. By default this setting is not enabled, and the client uses the loopback address (“localhost” or 127.0. 0.1) when it opens a socket for local port forwarding.

How does bind-socket connect to ports bound to IP?

Local processes connecting to such port will create a unix pipe instead of an IP socket. However if bound to the nic IP address the port is visible to the subnet.
