Network Configurations Manager

Scenario​

We aim to implement an application to run on a home router (Wi-Fi router) to manage network configurations: routing, port forwarding, firewall, Wi-Fi security, etc. The router runs a modern operating system - rich OS, like Linux. Other applications, such as a web service providing a user web interface, will interact with the configuration application through IPC mechanisms to query the state of network configurations and/or modify them.
