Lightweight firewall addition for ARM/HND based ASUS Routers using IPSet as seen on SmallNetBuilder
The goal of this tool is to enhance the firmware's built in functionality such as the SPI Firewall and Brute Force Detection 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 defence in your home network.

Skynet gained self-awareness after it had spread into millions of computer servers all across the world; realizing the extent of its abilities, its creators tried to deactivate it. In the interest of self-preservation, Skynet concluded that all of humanity would attempt to destroy it and impede its capability in safeguarding the world. Its operations are almost exclusively performed by servers, mobile devices, drones, military satellites, war-machines, androids and cyborgs (usually a terminator), and other computer systems. As a programming directive, Skynet's manifestation is that of an overarching, global, artificial intelligence hierarchy (AI takeover), which seeks to exterminate the human race in order to fulfill the mandates of its original coding.
