Hello @Quandary
Would you like to create a new post over in the Feature Requests to be able to import a list of firewall rules? This may be something that can be done more easily by the InControl2 team.
Here is some existing Feature Requests along the lines of what you appear to be asking for, you are welcome to put your voice to these also.
At the moment we are unaware of any way to have a list, i.e. saved in a CSV file, that can be uploaded into either the Peplink/Pepwave routers or InControl2 for the creation of firewall rules.
