Ahol akarod. Mivel a rouer gondolom doboz, így azon csak az ssh 
portforward működhet (ha nem herélték ki eljesen az ssh-t), mert nem 
tudsz rá telepíteni.

man ssh

DESCRIPTION

ssh (SSH client) is a program for logging into a remote machine and for 
executing commands on a remote machine.  It is intended to replace 
rlogin and rsh, and provide secure encrypted communications between two 
untrusted hosts over an insecure network.  X11 connections and arbitrary 
TCP ports can also be forwarded over the secure channel.

...

-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 con‐
nection 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 spec‐
ified 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.  How‐
ever, 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.
