Hi.

I´m making an script for load balancing of two
cablemodems internet connections toward my LAN.

The problem is that when I try to 'equalize' the
the two internet connections with the weight=1 it
doesn´t work. On the other hand, if I put 5 and 5
it works, but not at 100%, it does intermittlently,
some times works and others don´t.

example:

ip route add default equalize\
 nexthop via $P1 dev $IF1 weight 5\
 nexthop via $P2 dev $IF2 weight 5

Besides, when I open, for example, the firefox browser, it 
takes a lot to start navigating, sometimes it works and other
times gives an error and I can´t navigate.

From the server it works properly, but form the clients PCs
doesn´t.

By the way, I´m making NAT toward the Client PCs.

Do you have any idea why does it take so long to start
navigating and why sometimes it works and sometimes doesn´t.


This is the current script running in my server:
