Hi Everyone, We have firewall with 3 LAN Card, Eth0 is connected to my LAN, eth1 is Connected to Internet, and eth2 is connected to our Sister companies WAN. Since I am new to IPtables i dont know how to create a Rule to make the packet successfully reach its destination. This setup was made by a former sysad but left the firewall especially the connection going to the Sister Companies WAN un-configured. So that's the reason why Im here to seek help creating a rule for this firewall. Basically I want to achive the following. 1. Allow any IN and OUT traffic from eth0 to eth2 and vice versa. 2. Allow IN and OUT http traffic from eth0 to eth1. 3. Allow IN and OUT SMTP traffic from eth0 to eth1. 4. Allow Outgoing FTP traffic from eth0 to Eth1, Plus allow ESTABLISHED and RELATED FTP connection. Thanks,
