There are some known issues/limitations to be aware of:

  • Transparency is not possible in HA setups in Azure environments. For more information and requirements, refer to the Transparency Feature Description.
  • Do not downgrade from firmware version 7.2.36 or higher to a version below 7.2.36. If you do this, the LoadMaster becomes inaccessible and you cannot recover it.
  • The Virtual Service IP address must be the same IP address as the network interface.
  • Alternate default gateway support is not permitted in a cloud environment.
  • When setting up the LoadMaster in Azure, ensure that the Enable OS guest diagnostics check box is disabled because there is no support available for collection of diagnostics from the LoadMaster in Azure. If this option is enabled, the LoadMaster will not boot correctly.
  • It is not possible to bond interfaces on Azure LoadMasters.

The table below summarizes some of the limitations in Azure:
