Hi all. Just wondering if any of you having this same issue as I did. I've got NLB configured on 2 VM running on Hyper-V. Each of the VM equiped with 2 NIC. The NIC for heart beat purpose is configured with Static MAC and with the option "Enable Spoofing for MAC Address" enabled. Another NIC is for LAN communication purose. Each of the NIC is reside on a different VLAN (VLANx and VLANy). After I've got the NLB configured, with "unicast" mode. I've noticed I am not able to ping the NLB virtual IP address from any of the clients. Ping works between the NLB hosts, and is accessible. Once I've put all the NIC into the same VLAN, NLB works fine; I can ping the NLB virtual IP, and test on IIS works good. My question, does NLB requires all the host to reside in the same VLAN? If NLB support mulitple VLAN, then how can I configure it to support multiple VLAN (eg: production LAN NIC on VLANx, and heart beat NIC on VLANy)? Thank you.
