How can I configure the auto update server IP address when my CNUT is in a NAT environment?

It is possible with CNUT 2.2 to define the Auto Update Server address in a NAT environment. The default behavior is to auto-discover this address from the CNUT side. The override behavior is for the user to explicitly set the address as seen from the network element side.

If you have a single NAT in your system. Set this as the General Preference:
Edit->Preferences
(See attachment image001.jpg)

If you have multiple NATs. Then, for the top-most Network Element that defines that NAT, click on Modify and override the Parent/Default settings:
Edit->Modify Current Network Element Access
