Can I change the default subnet for the Gateway appliance private LAN?

[EcoStruxureIT]

Gateway appliance version 1.10 and newer

Yes. You can change the default settings from the Gateway appliance private network user interface.

See EcoStruxure IT Gateway appliance installation and setup - version 1.10 and newer

Gateway appliance version 1.9 and older

No. The Gateway appliance private LAN subnet must be 198.168.x.x. The IP address for the Gateway appliance is 192.168.0.1 by default.

You must contact support to change the Gateway appliance private LAN subnet to anything other than 192.168.x.x.

DO NOT USE WEBMIN TO CHANGE THE SUBNET FOR THE GATEWAY APPLIANCE PRIVATE LAN 

If you connect to Webmin on the private LAN and change the Gateway appliance IP address to a subnet other than 192.168.x.x, you will be locked out of Webmin, and completely locked out of the Gateway appliance. You must then call support to reset your appliance.
