Hello, Saeed! Replying to your letter: S> Hi all, S> I am new to list and have a basic nat question on Redhat Linux 9. I S> have to translate my local IP ( 192.168.1.0/24 ) to two different public S> IP given by two different ISP ( IPE1 & IPE2 ) at a specified rate. For S> example for every 4 received packet, one have to translate to IPE1 and S> other three to IPE2. I need this for load balacing the internet traffic S> between two isp. At the end, it is excellent if there is an option that S> If one the ISP gateway is dead, all packets have to translate to other S> public IP. Please help me. S> Thanks, S> Saeed Zamani, S> Technical Manager, S> Concept FZ LLC. I think, you can balance when you are connecting to another ports So, if you are connecting to port 80, you can NAT packets to IPE1, and another packets to IPE2 iptables -t nat -A POSTROUTING -p tcp --dport 80 -j SNAT --to-destination ipe1.ip.address iptables -t nat -A POSTROUTING -j SNAT --to-destination ipe2.ip.address -- Best Regards, Saeed!
