[clug] Enforce SSH tunnel to squid proxy

[Geoff Smith]

Howdy,

I'm trying to enforce the use of SSH tunnels on my network. I've got
squid running on a gateway box, and I can set up an SSH tunnel to port
3128 on that box no worries. 
The problem is that you can connect to the squid server even if you
aren't using an ssh tunnel. How can I change this so that only requests
going through an ssh tunnel get through? 

Cheers,

Geoff
