Service/port based routing

[geoffrey mendelson]

I have two routers on my network. let's say 192.168.1.1 and  
192.168.1.2. One connects to Netvision the other to 012. Now host  
based routing is simple, e.g. I can say route all packets to host  
1.2.3.4 via gateway 192.168.1.1 and using a default route, everything  
else via 192.168.1.2.

What I want to do is become more granular. I want to be able to route  
all packets to/from a specific port via one router, and everything  
else to use the
default route.

These are all connections to/from this particular system, I don't need  
to do it for everything on my network, or I can do it indiviudally.  
Currently the systems are running Ubuntu 9.04 with the latest kernel,  
but if I need to I can change them.


Thanks, Geoff.
