If you are using on the server TMG several networks (in array config) that have Internet access may be through My_Net1 or My_Net2. Balancing configuration does not work. There are no errors, but traffic is using a Windows routing table and pays no attention to balancing settings. To diagnose the cause, you can run the following commands in Powershell:
If you attempt to apply the settings on the network balancing My_Net1 and My_Net2 not lead to success.
Thus, balancing is only possible on the network of "External". If you want ISP Redundancy you need to remove the My_Net1 and My_Net2 of the array configuration.
