Hello, My server is on Mandrake 10.1 eth0 is WAN with static IP eth1 is LAN I am using iptables for firewalling. I am also running squid proxy. The reason I am running squid proxy is to allow / deny access to the net to clients systems. I use NCSA auth. If I were not to use squid proxy how can control access to net. Is there a way using iptables to control access to the net that is realable? Thanks Varun
