Hi.
 
Iīm 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
doesnīt 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 donīt.
 
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 canīt navigate.
 
From the server it works properly, but form the clients PCs
doesnīt.
 
By the way, Iīm 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 doesnīt.
 

This is the current script running in my server:
