SSH Tunneling Through Coporate Firewall

Hell to everyone. Long time reader. First time poster. I've searched and tried and searched and tried everything I can and can't get a specific SSH tunnel to work for me.

I am behind a corporate firewall. Ports 80 and 22 are open. I've been able to tunnel VNC to my computer at home with

ssh -t -L 5900:localhost:5900 'x11vnc -localhost -display :0'

I have a stock market monitoring program which only connects to a remote server on port 4000.

Is there a way to tunnel to this remote server with or without using my home computer?

Thanks for any suggestions. I just can't figure it out. Thanks for a great site. I've learned a lot here.

Your corporate firewall is more than likely going to block any tunnels it picks up and it may be something that could cost you your job so I'd double check that before you try too much.

In theory though you should be able to tunnel through as long as you have an open port on which to do so through the firewall. You could nmap scan it to find if the port is open but again you may want to be careful as port scanning your employers firewall could get you canned.

If you feel that you can't ask your system guys to assist you with your enquiry
it's safe to assume that this kind of usage is in breach of your workplace's
agreement on suitable computer & internet use, and as such we can't accept your
request for help here. Sorry. Very frustrating for a first time poster, I'm
sure, but them's the brakes.
