Routing IP Packets by port numbers

["Ian Perry" <iperry@inertia.com.au>]

Hi All,

I have a need to route packets to different places depending on the port
number.
For example:

Router1:	192.168.2.1 etho
		A.B.C.D	ippp0
		running sendmail, pop, apache etc

PC:		192.168.2.2 gw 192.168.2.1

Router2:	192.168.2.100 gw W.X.Y.Z

I want to send all traffic from the PC to the gateway on Router1, but I want
to send all traffic for port 80 to Router2.  I am using Slink on Router1.
Router2 is a Win98 Satellite system.

It becomes more complex as there are 2 other networks 192.168.2.X and
192.168.3.X also routed onto eth0 via a third router.

The system is actually up and running with the exception of Router2.
