[K12OSN] K12LTSP, Squid & SquidGuard

[Michael Elliott]

Hi Richard,

Thanks for the reply.  You are correct I was trying to use the server to 
connect to the internet.  When I logged in to a client machine, I then 
launched Mozilla and entered in one of the sample URLs that are supposed 
to be blocked.  As expected, it was open.  So I entered the preferences 
of Mozilla.  I changed the Direct connection to the internet to a Manual 
proxy configuration, I entered in the address of my K12LTSP 
(192.168.0.208) & Port 80.  To be safe I restarted the browser, but I 
received an alert - The connection was refused when attempting to 
contact the proxy server.  This was just going to google.com.  I then 
for the heck of it changed the proxy address to the LAN side IP address 
that is see by our main LAN (192.168.1.208).  Same alert.  So finally I 
attempted to change the proxy setting to "Automatic proxy configuration" 
setting to my K12LTSP address.  Unfortunately, I could get internet 
access to everthing once again.

Any advice grealty appreciated!
Michael
