Dear all,
    I have DSL (512kbs) connection and Cable (500+kbs in average) connection
at my home. I have connected both of them in my Linux (Redhat 9-2.4.20)
computer. I heard Linux can bond both connection together to get
1) Better bandwidth (500kbs+500kbs=1mb)
2) Redundency (in case of one link down)
    I am not expert in Linux but wish to get the experiment done. Wish
someone to guide me.
    The setting as follow
Cable from linksys router to eth0 with IP address 192.168.1.6
DSL connection from DSL router to eth1 with IP address 10.0.0.8
LAN Connection to eth2 (future NAT to all my clients in my home network to
enjoy Greater bandwitdh and Non-stop of the Internet)
    The kernel 2.4.20 already with working copy of iproute2 installed. The
default path to internet via eth0...

    I have tried the following command
#ip route replace default equalize \
nexthop dev eth0 \
nexthop dev eth1
ip route flush cache.
    Although the default routing table have changed, the internet connection
still go via eth0. I really don't know what goes wrong. I wish someone can
help me.

thanks a lot
