Hi ... I have 2 DSL lines all up and running on one RedHat box... 

I want to balance traffic going out over the two providers

The 2 DSL routers Have IP's 10.10.10.1 / 10.10.10.2 ... my linux box (eth0)
has IP 10.10.10.10 connected on a separate ethernet 

SO I read the http://lartc.org/howto/lartc.rpdb.multiple-links.html guide
(chapter 4.2.2)

In my case I have to make these routes

# ip route add default nexthop via 10.10.10.1 dev eth0 nexthop via
10.10.10.2 dev eth0

Works Fine!! every connection request going is perfectly balanced sent out
via both gateways
But works only on the linux box itself! from the (masqueraded) clients it
doesn't:

Every first  request which is masqueraded -> gateway 10.10.10.1 (works fine)
Every second request which is masqueraded -> gateway 10.10.10.2 (don't get
reply back)

When I change the multipath route so that 10.10.10.2 is the first hop

# ip route add default nexthop via 10.10.10.2 dev eth0 nexthop via
10.10.10.1 dev eth0

Gw 10.10.10.2 (fine) 
Gw 10.10.10.1 (doesn't work ... Only from the linux box itself)

So it every time seems to be the second "hop" in the multipath route which
isn't beeing masqueraded properly!

Can anyone help?

Thanks in advance! 
Niels!
