REDIRECT TRAFFIC : DOUBLE TUNNEL SSH
ssh -L PORT1:HOST2:PORT2 -N HOST1
It will listen connection on localhost:port1 redirect traffic through host1 (so you will need an account on host 1 -but not on host2-) and finally redirect traffic to host2:port2
example
from your localhost:9999 through 192.168.0.50 to 192.168.0.70:32400
ssh -L 9999:192.168.0.70:32400 -N 192.168.0.50
