    Hello,

    I am trying to make a load balance at my box using two conections. I have compile my kernel with this patch routes-2.6.13-12.diff (tha I get from this website: http://www.linuxvirtualserver.org/~julian/#routes).

    The problem is that when I try to balance using weight sintaxe (i will put the script bellow) some conectios just drop. So I can enter some pages but other I could not... What can I do?

    I am using this script (and reading this howto, again, to see if I missed something: http://www.ssi.bg/~ja/nano.txt):

--- SCRIPT ---

# Configuracao de redirecionamento de portas para os links
