Hello everybody,
I have been trying to buildup some ssh tunneling commands that would
allow me to create a ssh session to an machine behind an firewall from
an machine behind an firewall but with an public server in between. I
have spent an day trying to figure things out but without success. So I
wanted to ask for somebody help to get the right command...
I have added an attachment with ASCII art that should hopefully explain
my situation and what I would like to do.
Would somebody be willing to help me out?
Thanks in advance,
Jelle
