Configuring the management IP outside the management subnet succeeds without error.


Admin IP and Gateway for management route (/Common/default) not in a connected network.


On the LCD, navigate to the 'Setup' tab, and select 'Management'. 1. Set the default Gateway for the network. 2. Now set an IP address outside the Gateway subnet. 3. Notice no errors and commit is successful.


Do not configure the IP and Gateway outside the management route.
