SSH Dynamic Port Forwarding

SSH Dynamic Port Forwarding

VanDyke Software's terminal emulation client, SecureCRT®, gives you flexibility in how you securely access remote systems. SSH dynamic port forwarding provides the ability to access systems behind a firewall, allowing IT professionals to securely perform network administration tasks in a wider variety of complex network environments.

SSH Dynamic Port Forwarding Basics

Local port forwarding allows a local machine to tunnel traffic through an encrypted SSH connection. Dynamic port forwarding takes that one step further. While local port forwarding requires the connection to specify a source and destination port for each application, dynamic port forwarding simplifies how data is tunneled by acting as a SOCKS proxy on your local machine. So, all traffic to/from a SOCKS-compatible application is tunneled to a specified port on SecureCRT.

Benefits of SSH Dynamic Port Forwarding

SSH dynamic port forwarding has a number of advantages over other data tunneling methods:

  • It can be used when the application does not use a static port, as in the case of FTP
  • It allows you to access systems behind an SSH gateway server (AKA "jump server")

Dynamic port forwarding is a data tunneling option for SSH2 sessions, providing the security benefits of Secure Shell protocol: strong encryption, host and user authentication, and message authentication.
