How to configure routing tables

Hi all,

Actually I am simulating a load balance server. For that I need to
configure the routing table of a host(Decision Maker) say A, for other
two real server B and C. Such that, if for a perticular port any
request comes at Server A, it will redirect it to either B or C, based
on certain constraint(for this I suppose some algo are already
implemented in kernel, we just need to enable that service).
So could any body point out, that how to configure the routing table of
Decision Server(A) to get the above mentioned things done.

Any comment would be appriciated.

You need to enable IP forwarding and setup iptables on your router A,
specifically port forwarding. Google for something like "iptables port
forwarding howto".
