Iptables used to manage through chains and there are three type of chains
– INPUT : Control Incoming packet
– OUTPUT : Control Outgoing packet
– FORWARD : Control packet that are forward

– DROP : To disallow the packet
– REJECT : The target packet will be stopped.
– RETURN : Go to another chain of table.
