 This is my setup on a SuSE linux box (add to /etc/rc.d/route or
similar):

       /sbin/route del default 2> /dev/null
       /usr/sbin/ip route add default \
               nexthop dev eth0 via 192.168.0.1 \
               nexthop dev eth0 via 192.168.0.2 
       echo -e "Setting load balanced route (RoMaN) $rc_done"
       /usr/local/sbin/iptables -t mangle -A PREROUTING -j TOS
--set-tos 0x00
       /usr/local/sbin/iptables -t mangle -A OUTPUT -j TOS --set-tos
0x00
       echo -e "Hacking TOS to fix balance issue (RoMaN) $rc_done"

========

 192.168.0.1 y .2 are the adsl gateways. Iptables is used to trick the
TOS field and therefore sessions don't get messed.

 BTW, I've experienced some problems: from aprox 20 connections to my
stmp server I receive 1 connection failure. I don't know the reason.

 Try my config. Any feedback would be appreciated.
