Example — Using Remote Port Forwarding to Communicate Outside of a Firewall

This example demonstrates how a user in an enterprise environment can forward connections from a host on an external network to a host inside a corporate firewall.

myLocalHost% ssh -R 9022:myLocalHost:22 myOutsideHost

This command forwards connections to port 9022 on myOutsideHost to port 22 (the sshd server) on the local host.

myOutsideHost% ssh -p 9022 localhost
myLocalHost%

This command demonstrates how after the remote forwarding connection has been established, the user can use ssh to connect securely from the remote host.
