Hi,
I have recently developed a need to multiplex connections from within a 
NAT over several (hundred, even thousand if possible) external IPs. I 
can have all of these IPs routed to a single interface on my NAT box, 
however I am not exactly sure how to set up a random/round robin load 
balancing scheme such that outgoing connections from my network each get 
a random source address from my source address pool.

I have come across this how-to:
http://lartc.org/howto/lartc.rpdb.multiple-links.html

However it seems that I cannot scale these routing rules past 255 
routes, and unlike the example, I am not multiplexing interfaces but 
only IPs in roughly a contiguous /16 range being routed to this linux 
machine.

Any suggestions on how to get this up and running would be greatly 
appreciated.

Many thanks,
Chris Kanich
