[PLUG] Putty and firewall piercing

[Lee Marzke <lee@marzke.net>]

I had a situation where I needed to publish software to a Web server in 
the DMZ,  but
the firewall ( managed by a sister company ) only allowed proxyed 
requests ( port 80, 443 )
to the DMZ, and no SSH, FTP, or anything else.

Rather surprisingly I found that Putty includes a "proxy" tab in it's
configuration settings,  which does about the same thing as proxytunnel.

You might have to run a receiving SSH deamon on port 443 if the proxy is 
restrictive, but
other than that - Putty will then tunnel SSH right through the proxy.    
So outbound proxies
are really not that effective except in protecting the lusers.
