Open a remote tunnel
I have a question about tunnels in putty.
What I want to do is to open a ssh session to PC A from PC B.
PC B should open a tunnel to PC C, which is in a network, which can
only accessed from PC B.
Since PC A canīt connect to PC B directly, PC B has to initialize the
connection. Is this possible?
A simple Remote Port tunnel does not solve this problem, if I understood
That is how I think it should work:
PC A is 192.168.1.2
PC B is 192.168.2.2
PC C is 192.168.3.2
PC B has as route to PC A and PC B. The firewall denies access to PC B from
192.168.1.0 but allows outgoing connections.
I need a connection on port 3690 to PC C.
If a connection from PC A to PC B would have been allowed, this would work:
ssh -L 3690:192.168.3.2 -l root 192.168.2.2 from PC A
So is there a chance to have an indirect tunnel?
Thanks for any advises

Okay, sorry Iīve got it. It is indeed the switch -R make it work.
So the right command looks like:
From PC B
ssh -R 3690:192.168.3.2:3690 192.168.1.2
Now I can connect from PC A with localhost:3690 and everything works fine.
Oh what a fine day ;-)
