[nmglug] Multi-Homed Linux and Routing

[Tim Emerick]

I think I'm lost on "routes".  Forgive me if what I'm asking sounds uneducated.
   
  I'm assuming a route is how to get from here to a particular IP address. I don't want particular "routes" to run through eth1.  
   
  What I want is all traffic coming from tinyproxy to run through eth1.  All other traffic will run through eth0.  I can tell tinyproxy to use eth1 for incoming / outgoing requests via it's config files.  I just don't want non-tinyproxy traffic using eth1.
   
  I'm confused.
