Okay I have switched my proxy over to CentOS and followed the guide located on howtoforge: http://www.howtoforge.com/web-filte...4-and-windows-active-directory-integration-p2 I am up to the point of number 4 (second page) of connecting to the proxy for other workstations on the domain. I am able to use the proxy locally but cannot access it from other clients on the network. I have disabled Firewlld and SELinux. My output of netstat (after restarting): [root@proxy squid]# netstat -tanpl|grep squid tcp 0 0 0.0.0.0:3128 0.0.0.0:* LISTEN 6741/(squid-1) This is my current squid.conf which is only allowing localhost to work on MOST websites... http://pastebin.com/gLhZPU69 I've been tearing my hair out trying to set this up, so you are contributing to the quality of my hair. Thanks in advance.
