Hi Juan, I believe that what he is doing is going through an allowed port (such a port 80) and setting up an ssh tunnel to an external proxy server set to listen on that port (he may admin the box - could be at his home). this box then proxies his requests to the external web pages and sends the results back through the ssh session - as far as your firewall/proxy knows, the traffic is allowed so it doesnt stop it. possibly enabling authentication might stop this. hth kirk brady -----Original Message----- From: Juan B [mailto:juanbabi () yahoo com] Sent: Sunday, 21 August 2005 11:04 PM To: security basics Subject: ssh tunneling to bypass web proxy rules Hi, Someone told me one can pass web proxy restrictions by tunnling throw ssh to restricted web sites like web mail sites in our corporate network.I really whant to know how he is doing that but I dont know where and how to test it, and he of course doesnt tell.
