[LARTC] flow classification

[Ciprian Niculescu]

hello,

i have 2 links to the ISP of 128kbit each, and i want to balance the
trafic between them, but not staticly (local ip1-5 throw isp1, and the
rest to isp2). I though at a ingress clasification, then routing by the
mark, and at the exit nat (yes i must do nat :(((, but the clasification
must be flow based, and i dont know how to do it.

If certain IPs are always going through the same link, then you don't really want 
load balancing at all.
Don't you just want routing rules that say local ip1-5 always go through one gateway 
(isp1), and the default route is isp2 for everyone else?

Or did I misunderstand?

yes, you did, the 2 links are "practicaly" at the same isp, and i will
gain nothing if i do shortest_path routing
