Hello, I need to setup a very simple cluster for testing a couple different devices and applications. I'm not looking for perfection. What I have are 3 web servers in our test environment. We are testing both Windows and a Linux web server at the same time. We basically want to round robin traffic via IP to any one of the 3 servers. My understanding is that the following should make this happen: -A PREROUTING -d 10.0.16.89 -j DNAT --to 10.0.16.90-10.0.16.92 But it doesn't. I figure the next step would be to implement the CLUSTERIP but I'm not sure how to do this. I'd really like to do this at the firewall level as the production environment uses local director for load balancing. Is there a better approach without having to modify the OS? I'm not looking for failover but rather round robin. DNS hasn't been doing the round robin the way we wanted on the local LAN (as a single workstation will get stuck with a single IP for that session). Gary Wayne Smith
