I have the following configuration :
1) A tunnel is created between host W and H so I can connect to W from home on port 23000 through H :
on my laptop : ssh -p 23000 H and this brings me to W
2) H is a computer at home behind the DSL box, so there is a port forwarding from the box port 22 to H, thus I can do this from outside.
3) From home (on local network), allmost all ports are open on H (I guess), and I can do a port forwarding (don't know exactly if this is the right term) to connect through the tunnel on my work intranet. At work, we use a proxy P on port 8080. So using this :
ssh -L 8000:localhost:8080 -p 23000 H and configuring my local browser to use a proxy on port 8000 on localhost, it is just as if I was in the work intranet and using the proxy P.
4) Now, what i would like to do, is to do the same from outside. I opened the port 23000 on the box and redirected it to H:23000. But it does not work. Is it possible that when dealing with this, sshd tries to open new ports for data, and this is why I got this error : channel 3: open failed: connect failed: Connection refused ?
And if yes, is it possible to force everything to go through port 23000 ? Or to know which other port to open ?
Thanks a lot for any hint on this !
Julien
