Below is only examples: -
First, include this in /etc/iproute2/rt_tables as below: -
201 http.out 202 ftp.out 203 smtp.out 204 pop3.out
Next, include this in a preferred executable file such as /usr/local/bin/rc.routing as below: -
#!/bin/sh
# first ISP ip route add 1.1.1.68/30 dev eth2 src 1.1.1.70 table 1 ip route add default via 1.1.1.69 table 1
# second ISP ip route add 2.2.2.116/30 dev eth4 src 2.2.2.118 table 2 ip route add default via 2.2.2.117 table 2
ip rule add from 1.1.1.70 table 1 ip rule add from 2.2.2.118 table 2
ip route add 172.17.0.0/16 dev eth1 table 1 ip route add 2.2.2.116/30 dev eth4 table 1
ip route add 172.17.0.0/16 dev eth1 table 2 ip route add 1.1.1.68/30 dev eth2 table 2
ip route add default scope global nexthop via 1.1.1.70 dev eth2 nexthop via 2.2.2.118 dev eth4
ip rule add fwmark 1 table http.out ip rule add fwmark 2 table ftp.out ip rule add fwmark 3 table smtp.out ip rule add fwmark 4 table pop3.out
ip route add default via 1.1.1.69 dev eth2 table http.out ip route add default via 1.1.1.69 dev eth2 table ftp.out
ip route add default via 2.2.2.117 dev eth4 table smtp.out ip route add default via 2.2.2.117 dev eth4 table pop3.out
Next, include this in a preferred executable file such as /usr/local/bin/rc.firewall as below: -
#!bin/sh
iptables -t nat -A POSTROUTING -o eth2 -j SNAT --to-source 1.1.1.70 iptables -t nat -A POSTROUTING -o eth4 -j SNAT --to-source 2.2.2.118
iptables -t mangle -A PREROUTING -i eth1 -p tcp --dport 80 -j MARK --set-mark 1
iptables -t mangle -A PREROUTING -i eth1 -p tcp --dport 21 -j MARK --set-mark 2
iptables -t mangle -A PREROUTING -i eth1 -p tcp --dport 25 -j MARK --set-mark 3
iptables -t mangle -A PREROUTING -i eth1 -p tcp --dport 110 -j MARK --set-mark 4
Hope it helps...

Hi!
We have two ADSL link on the same server and we'd like to use load balance.
I tried to used, but I didn't have success.
I use on eth1 172.17.1.6 mask 255.255.0.0 my local network; on eth2 my first ADSL 200.168.1.19 mask 255.255.255.192 default gw 200.204.140.1 on eth4 my first ADSL 200.204.140.10 mask 255.255.255.192 default gw 200.179.1.1
This IP are static.
On my local network I have two servers (E-mail server and one web server) and I need to PREROUTING with DNAT.
And we would like to separate the port 80 and 21 using one link on eth0 and the port 25 and 110 other link eth4 and other ports eth0 or eth4 link.
My files:
My ifcfg-ethx files:
