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.
