Hi guys. I really need some = help.

This is my scenario:

CLIENTS -> SWITCH -> W2K Server -> = Linux -> Internet (with 2 ADSL LINES)

My RedHat Linux 7.2 is just a firewall. Im = running all the services (www, mail, etc.) on my W2K.

I tried to set up a load balance, but im = getting the following problem.

When I connect from the internet through my = IP1 (ADSL 1) on any port that I redirect to W2K, I can connect perfectly to my = W2K, but when I connect using my IP2 (ADSL2) I cant get to W2K.

And vice versa.

With the telnet server, which is running on = the linux, I can connect using both IP’s.

I guess the problem is when the W2K uses the = other gw.

My W2K default gw is the = linux.

This is my setup:

W2K IP -> 10.0.0.1 =

W2K IP2 -> 192.168.1.2

Linux eth0 = -> xxx.xxx.xxx.170 (ADSL1)

Linux eth0 gw -> = xxx.xxx.xxx.129

Linux eth1 = -> 192.168.1.1

Linux eth2 = -> yyy.yyy.yyy.205 (ADSL2)

Linux eth2 gw -> = yyy.yyy.yyy.193

IPTABLES (just the basic).

$IPTABLES -A INPUT -i = lo -j ACCEPT

$IPTABLES -A INPUT -p icmp -j = ACCEPT

$IPTABLES -A FORWARD -o eth0 -j = ACCEPT

$IPTABLES -A FORWARD -o eth2 -j = ACCEPT

##################### SMTP SERVER = #################

$IPTABLES -t nat -A PREROUTING -p tcp -d xxx.xxx.xxx.170 --dport 25 -j DNAT --to-destination = 192.168.1.2

$IPTABLES -t nat -A PREROUTING -p tcp -d yyy.yyy.yyy.205 --dport 25 -j DNAT = --to-destination 192.168.1.2

##################### HTTP SERVER = ##################

$IPTABLES -t nat -A PREROUTING -p tcp -d xxx.xxx.xxx.170 --dport 80 -j DNAT --to-destination = 192.168.1.2

$IPTABLES -t nat -A PREROUTING -p tcp -d yyy.yyy.yyy.205 --dport 80 -j DNAT --to-destination = 192.168.1.2

$IPTABLES -t nat -A POSTROUTING -s = 192.168.1.0/24 -j MASQUERADE

$IPTABLES -t nat -A POSTROUTING -s = 10.0.0.0/24 -j MASQUERADE

$IPTABLES -t nat -A POSTROUTING -o = eth0 -j MASQUERADE

$IPTABLES -t nat -A POSTROUTING -o = eth2 -j MASQUERADE

And this is my load balancing = script:

#### Variables ######

IP=3D/sbin/ip

IF1=3Deth0

IP1=3Dxxx.xxx.xxx.170

P1=3Dxxx.xxx.xxx.129

P1_NET=3Dxxx.xxx.xxx.128/26

IF2=3Deth2

IP2=3Dyyy.yyy.yyy.205

P2=3D yyy.yyy.yyy.193

P2_NET=3D = yyy.yyy.yyy.192/26

echo 201 t1 >> = /etc/iproute2/rt_tables

echo 202 t2 >> = /etc/iproute2/rt_tables

$IP route add $P1_NET dev $IF1 src $IP1 table = t1

$IP route add default via $P1 table = t1

$IP route add $P2_NET dev $IF2 src $IP2 table = t2

$IP route add default via $P2 table = t2

$IP route add $P1_NET dev $IF1 src = $IP1

$IP route add $P2_NET dev $IF2 src = $IP2

$IP route add default via = $P1

$IP rule add from $IP1 table = t1

$IP rule add from $IP2 table = t2

$IP route add default scope global nexthop = via $P1 dev $IF1 weight 1 nexthop via $P2 dev $IF2 weight 1

I really need help.

I appreciate it,
