How to SSH an outside server from a computer which is behind a proxy firewall?

I access the Internet through an HTTP proxy firewall at college. And I need to login to a computer, via SSH, which is outside our network. I tried it as Linux command and on Windows using PuTTY. I also configured PuTTY to use our server's address. But still, "Proxy error: 403 forbidden" pops up. They must've blocked SSH access to outside systems. (college systems as accessible).

"@blahdiblah from what I understand his problem is not SSHing to the local webserver, its SSHing out of his network.

If they are blocking outgoing connections to port 22 it doesnt matter were he tries to SSH from, it will be blocked. Unless the firewall would be setup to allow the webserver to initate an outgoing connection on port 22 but i doubt it.

The way I see it is what shf301 said, you need to change the port on your SSH server to something they wont block, like 443 or 80 then, you will have to SSH to the websrver and from there ssh to your outside server.

Let us know how you fix it.

Good luck."
