Hello, My server is on Mandrake 10.10ff. eth0 is WAN with static IP connected to 512Kbps DSL. eth1 is LAN. Using webmin - networking - Linux firewall, I have done a NAT on eth0. After I did NAT on eth0 I see that all clients can access straight away the internet without any settings. Is it Ok ? Next I would like to use packet filter and redirect all port 80 to port 3128. I have tried as follows : accept - If protocol is TCP and input interface is eth1 and destination port is 3128 and source port is 80 Is it Ok ? Please correct me as I am a newbie to iptables. Thanks Varun
