I went back and read thru the earlier posts. Let me make sure I
understand the situation completely.
You have a network. There is a firewall. There is a separate proxy
server running squid and squidguard.
If a user sets up the proxy settings in his browser to use the proxy
server then all traffic is properly handled by all systems and the user
really does get proxied. If the user goes to a blacklisted site (in
squidguard blacklists) he is blocked etc. etc.
If that is all correct then the next step is that you want to STOP users
from getting through the firewall directly so as to force the traffic
through squid.
OR you have the firewall checking with squid to allow or deny the user
based on squid's response--but this is less common i think.
Once you have stopped all direct traffic going directly through the
firewall make sure the proxy can still get through the firewall.
After you have stopped all direct traffic then work on transparently
redirecting traffic to the squid box.
Note: i found this on the net

I don't know if this will help or not but it helps me to go over a
problem from start to finish to see if I have missed anything.
