I have scoured the net, gotten a few pointers from several people and looked at
several books and still have not come up with a satisfactory solution.
 
I know someone has done it!  
 
Can some one point me to a reference for how to route two wan nics and two
internal nics on the same box.
 
I have tried using ip add to setup two separate lookup tables and route tables
but to know avail. Any help greatly appreciated!
 
This is what I have
