Greetings! to all, Please, look into my problem and help me. I am quite a newbie squidish. 1. my squid server is ready for serve requests. 2. it is on a firewall too. 3.WAN connection (DSL) from eth0 is with DHCP. but my LAN connection is (eth1) with static IP. 4.client's access is given by MAC address, no other authentication is required. 5. almost all the settings as per the default values in squid.conf. (pls, somebody figure me out what is unnecessary for me in my squid.conf file which I don't understand). 6. I want Firewall+proxy+caching for my LAN of 20 PCs. 7. My problem is I can not connect IE clients to the Squid server with my settings (pls see, given below squid.conf file). 8. Since I am a newbie, I hope your generous assistance. 9. Pls, see below for my squid.conf file and squid -NCd1 command.
