Ladies and Gentlemen, Greetings and Felicitations!
I don't want to know how to do this but where I should look to find
the answer. For the life of me I can't find it, mostly (I think)
because I don't know what the technical term for what I want to do is,
and so I can't google for it.

We have a bunch of servers on our network, each with one NIC in them,
and a large number of thin clients connect to any of these servers. I
want to add a second NIC to each server and route all Internet traffic
(http) through one and everything else through the other. To put it
another way any traffic to port 80 is to go to one NIC and traffic to
any other port to the second NIC. I intend to send all internet
traffic through a completely separate network at some stage and the
first step is to split the traffic up. I know that it can be done I
just don't know where to look to find out how.

We really only have three types of traffic; tftp (when the clients
boot), X (when the clients are running) and internet (when the kids
are surfing).

We are using FC1, 2.4.22-1.

many thanks!
