I've got a question about port forwarding....

I have a machine that will be located remotely. I have ssh installed
on this machine. I cannot install any sort of VPN on this machine.

The machine will be behind a firewall, so I need a way to access this
machine.

What I'd like to do is set up a persistent ssh connection to my server,
and then portforward back through this connection so I can connect to the
ssh server on the machine.....

One more time:

machine A is at my desk.

machine B is far, far away.

Machine B connects to machine A via ssh, forwarding some port that
connects back to itself....

I use ssh localhost -p someport on machine A to log into machine B.

I've been playing around with all sorts of ways to try to portforward
using -L and -R, but I always get something that doesn't work or a message
that the port cannot be forwarded.....

I've found all sorts of docs on how to forwards ports if I want to tunnel
in the same direction as the ssh connection, but nothing that tells me how
to tunnel 'backwards'....

TIA,
