Projects / fli4l


fli4l is a single-floppy Linux-based ISDN/DSL/ethernet-router. It features configuration with some simple ASCII-files, several possible connection-flavors (in/out/callback, and raw IP/PPP), channel bundling (an extra channel can be added through a Windows/Unix-client), configuration of multiple networks, least-cost routing, automatic choice of provider, display/calculation of connection times and costs, and a Windows/Unix client to control dial/hangup, monitor traffic and monitor incoming calls on ISDN (see screenshot).

            Thank you
            Hi ^^

            I'd like to thank the development team for this good thing. It saved me a lot of problems (I had a so-called "hardware - router" before, and it didn't work well; portforwarding sucked).
