.Synopsis
Establishes a Dynamic Port Forward thru a stablished SSH Session.
.DESCRIPTION
Dynamic port forwarding is a transparent mechanism available for applications, which
support the SOCKS4 or SOCKS5 client protoco. In windows for best results the local address
to bind to should be the IP of the network interface.
