Hello, eveyrone.
I have a problem with my WNLB set up. The NLB group has 2 Windows 2003
server nodes.
ClusterIP: 192.168.100.68
Node1: 192.168.100.66
Node2: 192.168.100.67
I use multicast. I have a Layer3 Foundry switch.
I need to load balance just port 8080 between them.
After the WNLB setup was done, The cluster shows the 2 nodes converged.
But node1 does not receive any packet at all.
I tried to load balance and fail-over between the two node2. It turned
out that is not working.
To simulate the fail-over, I stopped the app that runs port 8080 on
node1. The app on node2 does not respond to my request on the virtual
ip/name at all.
I did a queryport. It showed that port 8080 on node1 received no
packets.
Please help.
Please see my NLB config below.
