hi!

Brazilian I and do not say English, I forgive for any error!

I have a FreeBSD Server (5.4). This server links ADSL has two, and I need to
balance the load between them, e also case one stops the other keeps the
connection.

My system is thus:
==============
rl0 ----> IP=192.168.2.254/24 / GW for machines in this net is
192.168.2.254- (this is localnet NIC)
rl1 ----> IP= 10.0.0.2/30         / GW for this net is 10.0.0.1 -  (adsl1)
sis0 --> IP= 10.0.1.2/30         / GW for fhis net is 10.0.1.1 -  (adsl2)
#########################################################################

I have two NATD process, see below:
===========================

318  ??  Ss     0:00.39 /sbin/natd -f /etc/natd.conf -p 8668 -n rl1
1815  ??  Ss     0:00.65 /sbin/natd -f /etc/natd1.conf -p 8669 -n sis0
#########################################################################

And my firewall :
============

ipfw add 10 divert 8668 all from any to 10.0.0.2 via rl1
ipfw add 11 divert 8669 all from any to 10.0.1.2 in via sis0
ipfw add 12 prob 0.5 divert 8668 all from any to any out via rl1
ipfw add 13 divert 8669 all from any to any out via rl1

ipfw add 30 fwd 10.0.0.1 all from 10.0.0.2 to any
ipfw add 30 fwd 10.0.1.1 all from 10.0.1.2 to any
#########################################################################
and my default route is: 10.0.0.1, I need to make the balancing between
these interfaces.

when I apply these rules nothing I function. I I followed a manual in the
Internet (
http://wiki.luizgustavo.pro.br/doku.php?id=artigos_freebsd:balancelinks),
but without success.
