We have completed an installation of 3x WAS IBM HTTP servers running on an I570 Server. Separate from this is an IBM X3550 Edge Server, running load balancer program as well. The Edge server has an IP address on the physical NIC and the Load balancer Server has a cluster IP which is a virtual address. The workstation in our LAN .../23 can all see the ping the .220 & .229 IP. However the workstations on the WAN can only intermittently see the IP of the cluster, which is .229. They can see without issues ping the physical nic of the Edge server (.220). I have check my routing, and the routing of each of the workstation outside the WAN, they all point to the correct Server. I do for example a ping to the same server with both IP's and the result can be seen on the attachments. Please help because this is coming to a point that it's becoming a big frustration.
