Iptables forward traffic to forward chain!!!

Hi,
I am new to linux stuff. I want to use linux iptables to configure rule so that all my incoming traffic with protocol "tcp" is forwarded to the "FORWARD CHAIN". The traffic i am dealing with has destination addresss of my machine but i want to block it from coming to input chain and somehow wants it to be forwarded to the "FORWARD CHAIN". Desperately needs this help. Thanks
