Maybe following scheme can help you understand how to
apply
ssh-tunnel:

# Local ssh-tunnel:
#    client$ ssh -L port:host:hostport server
#
# Talking to 'port' on client, will forward
# everything to 'hostport' on host:
# --------          --------              ------
# |client|-port>--->|server|>--->hostport-|host|
# --------          --------              ------
#
#
# Remote ssh-tunnel:
#    client$ ssh -R port:host:hostport server
#
# Talking to 'port' on server, will forward
# everthing to 'hostport' on host:
# --------          --------              ------
# |server|-port>--->|client|>--->hostport-|host|
# --------          --------              ------
#
#
# The client/server communication is ssh-encrypted.
# Communication to host is in clear text.
#
# Client & server require login ID, but host doesn't.


Does that help?
