Hi.

I=B4m making an script = for load=20 balancing of two
cablemodems internet connections toward my = LAN.

The problem is that = when I try to=20 'equalize' the
the two internet connections with the weight=3D1 = it
doesn=B4t=20 work. On the other hand, if I put 5 and 5
it works, but not at 100%, = it does=20 intermittlently,
some times works and others don=B4t.

example:

ip route add default=20 equalize\
nexthop via $P1 dev $IF1 weight 5\
nexthop = via $P2=20 dev $IF2 weight 5

Besides, when I open, = for example,=20 the firefox browser, it
takes a lot to start navigating, sometimes = it works=20 and other
times gives an error and I can=B4t navigate.

From the server it = works properly,=20 but form the clients PCs
doesn=B4t.

By the way, I=B4m = making NAT toward=20 the Client PCs.

Do you have any idea = why does it=20 take so long to start
navigating and why sometimes it works and = sometimes=20 doesn=B4t.

This is the current script running in my server:
