Windows NLB - Multicast - When adding second host, both stop communicating with each other

    Întrebare

  • Hey,

    I ran into a problem today, when trying to configure NLB for 2 Hyper-V servers.

    Both Hyper-V servers have MAC Spoofing enabled. Also they are on a different subnets stationed in different locations.

    When creating a cluster and adding 1 host to it, either 1st or 2nd server, it works fine, I can ping host and cluster.

    Then when adding second host, they suddenly lose connection to each other and I can't seem to ping one from the other. Though they are reachable from any other machine. This does not affect Cluster as it is still reachable from both hosts.

    I even tried creating Cluster for those 2 hosts from a 3rd random machine, but it all acts crazy and hosts are showing the same cluster, but they have only their own host names in it, while Cluster is showing both when managing from 3rd random machine.

    Hope explanation makes sense and I would really appreciate your support !

  • Hey,

    Thanks for your reply.

    I found out, by reading a few other forums, that NLB will not work on different subnets.

    What I was trying to do is to set up a Cluster 192.168.100.23 with 2 hosts that were 192.168.100.24 and 192.168.40.24

    It seems that this configuration is not supported.

    Everything is working now on the same subnet !
