I've got the proxy work great with setting the browser configuration. Now I'm trying to get the transparent piece working so I added the "http_port 3128 transparent" and set the IPTABLES rule to route the packets from 80 to 3128. I can see that this piece is working as it's logging my attempts in the squid/access.log file. In switching between transparent and not-transparent I see that the source IP address switches from 127.0.0.1 (not-transparent) to my local PC IP address in transparent mode. I think because of this I'm getting an access denied. Trouble is... What in squid controls this? Any ideas? Thanks! Scott
