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

NAME
upnpd.conf - upnpd(8) configuration file SYNOPSIS
upnpd.conf DESCRIPTION
upnpd.conf contains the configuration details to do with run-time of upnpd(8). Configuration items related to starting the daemon such as interface names are defined, for Debian, in /etc/default/linux-igd. OPTIONS
iptables_location The full path and name of the iptables executable, (enclosed in quotes). Example: iptables_location = "/sbin/iptables" debug_mode Daemon debug level. Messages are logged via syslog to debug. 0 - no debug messages 1 - log errors 2 - log errors and basic info 3 - log errors and verbose info default = 0 Example: debug_mode = 2 create_forward_rules Should the daemon create rules in the forward chain, or not. This is necessary if your firewall has a drop or reject policy in your forward chain. allowed values: yes,no default = no Example: create_forward_rules = yes forward_rules_append Should the daemon insert or append rules in the forward chain. Normally you will want to insert rules at the beginning of the for- ward chain, so that they apply before any drop or reject rules later in the chain. This option only applies if "create_for- ward_rules = yes". As an experiment, this setting now also affects the PREROUTING chain in the same way. If this causes you problems please let me (Debian maintainer) know through the BTS. Tip: If you need to insert rules somewhere in the middle of the PREROUTING or FORWARD chains, instead of first or last, then you should create a new empty chain, e.g forwardUPnP, and set forward_chain_name to that chain. Then insert a rule to jump to for- wardUPnP in the appropriate place in the PREROUTING or FORWARD chain. (The value of forward_rules_append probably won't matter much in that case.) allowed values: yes,no default = no Example: forward_rules_append = no forward_chain_name The name of the chain to put the forward rules in. This option only applies if "create_forward_rules = yes". allowed values: a-z, A-Z, _, - default = FORWARD Example: forward_chain_name = FORWARD prerouting_chain_name The name of the chain to put prerouting rules in. allowed values: a-z, A-Z, _, - default = PREROUTING Example: prerouting_chain_name = PREROUTING upstream_bitrate The internet line upstream bit rate reported from the daemon. Value in bits per second. default = 0 Example: upstream_bitrate = 512000 downstream_bitrate The internet line downstream bit rate reported from the daemon. Value in bits per second. default = 0 Example: downstream_bitrate = 512000 duration The default duration of port mappings, used when the client doesn't specify a duration. Can have the following values: 0 - no default duration specified seconds | HH:MM - duration from the time of addition @seconds | @HH:MM - expire mapping at the specified time of day default = 0 Example: duration = 86400 # One day xml_document_path The path to the xml documents. Do not include the trailing "/". default = /etc/linuxigd Example: xml_document_path = /etc/linuxigd description_document_name The name of the igd device xml description document, underneath xml_document_path. default = gatedesc.xml Example: description_document_name = gatedesc.xml listenport The UPnP port to listen on. default = 0 (first free UPnP port, starting with 49152). Example: listenport = 0 paranoid Paranoid forwarding setting. Can have the following values: 0 - allow internal hosts to forward to any other (internal) host. 1- only allow internal hosts to forward to themselves. default = 0 Example: paranoid = 1 SEE ALSO
