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 below 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 is ignored. If a variable is already defined it will be used when downloading and executing. The subnets are hierarchical structured and the network that is most compatible with the device accessing 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. If the execute in the toolbox is used and the executable directory is changed to costum, a path can be entered. It will be checked if the variable from the path exists and can be replaced. For example if you enter \$NAS as the path, nas can be overwritten on the hardware. This is especially useful when you need different variables on sub-devices.
