OpenSSH est un logiciel serveur (sshd) et client aussi (ssh) ;-)
Et les deux supportent le port forwarding

man ssh
C'est l'option -L coté client
Coté serveur, c'est activé par défaut, mais je ne me rappel plus quelle option
l'active

     -L [bind_address:]port:host:hostport
             Specifies that the given port on the local (client) host is to be 
forwarded to the given host and port on the remote side.  This works by
             allocating a socket to listen to port on the local side, 
optionally bound to the specified bind_address.  Whenever a connection is 
made to
             this port, the connection is forwarded over the secure channel, 
and a connection is made to host port hostport from the remote machine.
             Port forwardings can also be specified in the configuration file.  
IPv6 addresses can be specified with an alternative syntax:
             [bind_address/]port/host/hostport or by enclosing the address in 
square brackets.  Only the superuser can forward privileged ports.  By
             default, the local port is bound in accordance with the 
GatewayPorts setting.  However, an explicit bind_address may be used to bind 
the
             connection to a specific address.  The bind_address 
of “localhost” indicates that the listening port be bound for local use only, 
while an
             empty address or ‘*’ indicates that the port should be available 
from all interfaces.
