Proxy und NAS variables should be used.
To define variables in an IP plan, you must configure the variable under IP Plan, Subnet. If you press "Create new Subnet", you can specify what the subnet is about.
This configuration is automatically specified when downloading the IP plan. The same applies to Wuinstall download and install. If a variable is already defined, it will be ignored and will be used already during download and execution. The subnets are hierarchical structured and the network that is most compatible with the accessing device is always chosen. If a new configuration is added, it is also inherited hierarchically.
When creating a new job, you can override proxy and nas. When " Execute" in the Toolbox is used, and the executable directory is changed to "Custom", a path can be entered. It is checked whether the variable from the path exists and can be replaced. This is especially useful when you need different variables on sub-devices.
For example, if "\$NAS" is entered as the path, you will be able to overwrite nas on the hardware.
