ImmortalWrt is an embedded network operating system for routers and network hardware. Built as a Linux distribution based on OpenWrt, it functions as a firmware builder and operating system designed to manage routing, switching, and firewalling.
The project extends the OpenWrt base by providing additional drivers and pre-configured software packages. It includes a toolset for compiling tailored system images from source to match specific hardware architectures and chipsets.
The system features a web-based management interface for device administration and a modular package manager for installing software components. It utilizes a unified configuration interface to abstract system settings and integrates networking protocols and firewall rules at the kernel level.
