Any suggestion help.. You want to use "Policy based Routing". ( http://en.wikipedia.org/wiki/Policy_based_routing ) The principle is to use iptables to set a numeric mark (-j MARK) on packets according to you criteria (tcp destination port number, ...) and to use a different routing tables which are selected according to this packet-marks.
