What is SSH dynamic port forwarding?
Dynamic port forwarding allows you to create a socket on the local (ssh client) machine, which acts as a SOCKS proxy server. When a client connects to this port, the connection is forwarded to the remote (ssh server) machine, which is then forwarded to a dynamic port on the destination machine.
How do I port forward SSH using PuTTY?
Click on the small icon in the upper left corner to access the Putty Menu, then click on Change Settings… Enter port number as the Source port and host:port as the Destination, then click Add. Check both boxes at the top: Local ports accept connections… and Remote ports do the same…
What is dynamic SSH tunneling?
Dynamic SSH Tunnel (Dynamic Port Forwarding) Aside from traffic forwarding, proxy servers provide security by hiding the actual IP address of a client. A SOCKS proxy routes any type of traffic generated by any protocol or program to the actual server on the behalf of the client.
What requires dynamic port forwarding?
Dynamic port forwarding (DPF) is an on-demand method of traversing a firewall or NAT through the use of firewall pinholes. The goal is to enable clients to connect securely to a trusted server that acts as an intermediary for the purpose of sending/receiving data to one or many destination servers.
What is a dynamic port?
A dynamic port — also called a private port — is one that is assigned to a process or service at the time the port is needed, usually when the process or service is started. When assigning dynamic ports, the OS can use any ports available from the range of ports designated for this purpose.

What is difference between static port and dynamic port?
For static port applications, the Netlet rule includes the destination server port so that requests can be routed directly to their destinations. Dynamic applications agree upon a port for communication as part of the handshake. You can include the destination server port as part of the Netlet rule.
What is the difference between SSH and PuTTY?
PuTTY is a terminal emulator (able to run shells, which in turn run commands), while the usual SSH application is a shell (not a terminal emulator). PuTTY has been ported to Unix (and Unix-like) systems as pterm . scp is a special case: a program use for copying a few files via an ssh connection.
