SSH Port Forwarding is primarily a single-user pursuit, and any access by multiple users should be approached with considerable caution. Initial setup can also be a bit tricky, and we recommend that you create scripts to assist you in recreating the forwards you need. Within these limitations, SSH Port Forwarding is an extremely useful extension to the security provided by SSH, allowing you to encrypt many other applications that didn't originally present a security risk in an unencrypted form.
