Dear List.
I try to build multipath connection w/ load balance to internet with two
different gateway;
My system is RH-8.0 with iproute-2.4.7-7.90.1.rpm and Kernel-2.4.26
(patching with Julian A. patch),and follow guide from
http://www.linuxvirtualserver.org/~julian/nano.txt,
The problem is;
when i try to connect to Internet form gateway machine it;s success ,
but only one interface is active, no load balancing at all ,
This is my default table
#ip r ls table DEF
default proto static
nexthop via 172.16.0.1 dev eth0 weight 256 dead onlink pervasive
nexthop via 192.168.0.1 dev eth1 weight 1
I search the list about this error, and found that i shall use the
upgrade version of iproute2, and i compile that too.
but with same config, and new iproute2 i can''t connect to internet now.
please be advice, what wrong with my config (attach), and what version
of linux should work ?

Make sure after upgrading iproute2 that your nexthops are not dead. Also, list you rules and routes and make sure they are valid, I see your commands but I do not know which of them are accepted from the kernel.

Hello, To all: do you have some working script(s) that we can recommend for setups with 2 or 3 uplinks in multipath route? Then we can link them to the web page as reference.
