Skynet - Asus Firewall Addition
Skynet is the first comprehensive IP banning and security tool exclusively for Asus Devices.
The goal of this tool is to enhance the firmware's built in functionality such as the SPI Firewall, Brute Force Detection and AiProtect while adding easy to use tools for users to implement custom firewall rules they desire. Skynet has a range of feature from banning single IPs, domains, entire countries or pulling predefined malware lists from reputable providers. It is the one stop shop for router security and the first line of defense in your home network.
Skynet fully supports (router) OpenVPN implementations and the
Astrill VPN Plugin along with user scripts like
Diversion. You can read about explanations for common errors
here.
This script is open source and free to use, but if you want to support future development you can do so by
