Load balancing : route based

Dear all,

I'm curently setting up a gateway (linux 2.6.7) with load balancing (
multipath ).
I acces them from lan and my external interfaces are NATed.
I'm used iproute2 as described in the LARTC and nano howto.

My problem is that connections are well balanced but often, long connection
are break because the default route change during the connection.
I've not used equalize because i've read that this is packet-based...


This seem to don't appear when transfert is initiated from the gateway..
The break seems to appear about every "/proc/sys/net/ipv4/route/max_delay"
minutes...
What is the problem ?

Thanks for your help !
