We are in the process of setting web servers that will use NLB to share the load.
Two of the servers set on our internal network and are setup in their own NLB cluster.
The NLB cluster is set to unicast.
Each server has one network adapter. These adapters have been added to the cluster.
Each server needs to be able to communicate with an SQL server. At this point only one server in the cluster can do so.
If I switch the cluster to multicast each server can communicate as expected individually. However we are unable to communicate with the cluster interface IP thus rendering the cluster ineffective.
We have two more servers that sit in our DMZ that are on their own NLB cluster as well.
Their NLB cluster is setup the same as the internal cluster.
The DMZ servers need to communicate with the same SQL server as the internal servers.
We are having the same issue with the DMZ servers.
Any guidance would be appreciated.
