I have a Windowns NLB Cluster with a static IP. When I shutdown the NLB Cluster and give the IP to a Virtual IP on a Kemp LoadBalancer it doesn't work. I can use the same configuration for a new IP and everything works perfectly in the Kemp LoadBalancer. When I run a tracert on old IP, it goes to Kemp LoadBalancer but takes a long time -- series of Time Outs. I'm not a networking person -- why would a changed IP not work, when a new IP will? Thanks in advance.
It NEVER responds to an arp request with a real MAC address. for the virtual IP... this causes the switch to broadcast it to ALL ports in the VLAN.
So if you configure one system with the real IP all traffic will always goto to THAT port only. ==> no access.
Windows Clustering cannot work without that method. (The cluster members need to coordinate between the nodes which one will answer which requests).
