Kemp LoadMaster 1000 directing HTTP traffic to 2 Sharepoint 2010 WFE’s and Sharepoint Authentication mode is Windows Authentication.
I configured the Kemp LoadMaster with the two target SharePoint servers for the HTTP protocol. The status of the virtual service in the LoadMaster indicated that the service was up and running (green light) and I could ping the virtual IP and get a response but the web page would not load.
By default when creating a virtual service on the LoadMaster Layer 7 Transparency is turned on. This was causing the pass-through authentication to fail. Disabling Layer 7 Transparency fixed the issue.
