Hi all, How do I enable mail clients like outlook express on client machines while filtering internet access through squid? I went through lot of forums and looks like it is possible through iptables. I tried with that but am not getting the correct settings. Also I want to enable one particular mac address, if possible, else ip address to access internet without routing through squid but all other clients on the network to access through squid. Is it possible? Any help would be highly appreciated. -- Regards Gorav
