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.
