OpenWRT 23.05.3

OpenWRT is a Linux distribution for wireless routers and low-resource embedded devices. It provides a coherent base system for different plattforms, various hardware and firmware drivers, and a Debian-style packaging system for application and add-on packages. The JSON-RPC based admin web interface LuCI makes configuration very user-friendly, but keeps the similar SSH and command line UCI interface and /etc files accessible. With its own PROCD system event daemon it can immediately respond to updated device states and settings. As router distribution it includes stateful firewalling, WAN interface and VLAN route configuration, port forwarding, wireless drivers, IPv6 support, UPnP, TR-069, DHCP, DNS, RADv6, mesh networking, VPN, QoS management, a writeable root filesystem, print and file servers, media sharing, telephony systems, and much more.
