Hello,

I am trying to make a load = balance at my=20 box using two conections. I have compile my kernel with this patch=20 routes-2.6.13-12.diff (tha I get from this website: http://www.lin= uxvirtualserver.org/~julian/#routes).

The problem is that when I try to = balance=20 using weight sintaxe (i will put the script bellow) some conectios just = drop. So=20 I can enter some pages but other I could not... What can I = do?

I am using this script (and = reading this=20 howto, again, to see if I missed something: http://www.ssi.bg/~ja/nano.txt):
