Check your iptables config, I bet you'll see some logging about port 3128. If you run the web server on port 80, you'll not be able to run the proxy on port 80. Since I think IE sucks, I don't know how to config it to use the .pac file, but under mozilla you can go to Edit->Preference->Advanced->Proxies and choose automatic proxy configuration URL, just put a file like this on your web server and plug the url into the automatic proxy configuration. function FindProxyForURL(url, host) { return "PROXY 10.100.100.130:3128"; } Bit the bullet and change your IE browsers to look here as well. -- Minneapolis St. Paul Twin Cities MN | Phone : (952)943-8700 http://www.mn-linux.org Minnesota Linux | Fax : (952)943-8500 Key fingerprint = 6C E9 51 4F D5 3E 4C 66 62 A9 10 E5 35 85 39 D9
