Function FAQ

Q: | Does FLI4L support analogue modems for internet connections ?
A: | No. You will find better support for this in the project: LRP . See also http://www.linuxrouter.org
Q: | Does FLI4L support ISDN modems or telephone knots via COM (serial) or USB port ?
A: | No. FLI4L does only support ISDN adaptors. ISDN modems act as normal analogue modems. Again LRP would be best in this case.
Q: | But there IS a driver for (ex.) Eumex 504PC under: http://www.atlas.uni-wuppertal.de/~harenber/eumex.html for Linux, to use the Eumex via serial port. Will this be integrated into FLI4L in the next time ?

A:

No. The introductional text already says: The driver contained in this page is legal property of Deutsche Telekom and is copyrighted...! That means: Since there are copyrights for these drivers existing (the same as it is for CAPI driver of AVM), there will be no integration into FLI4L, because FLI4L will loose its GPL status.

Q: | Is Dial-On-Demand possible?
A: | Yes, that is the default status of FLI4L. You may additionally switch the router to manual dialing.
Q: | Am I able to use several connections to different providers and will I be able to connect additionally to my companyīs intranet ?
A: | Yes; you may configure several (so called) circuits in FLI4L for this. Two connections at a time are possible.
Q: | Is FLI4L able to bundle ISDN channels ?
A: | Yes; it is possible to use two combined channels by using the IMON client for Windows, Unix or Linux - IF your ISP enabled this function for you (combining channels as given in RFC1717).
Q: | Can FLI4L be used as a least-cost-router ?
A: | Yes; you will only have to create necessary tables on your own. Thatīs no big problem - should be done in a few minutes.
Q: | Is there any output of charges of connections ?
A: | Yes; these costs will be displayed in imon client (for Windows and/or Unix/Linux), if they were configured before.
Q: | May I use FLI4L as dialing-in router?
A: | Yes; see documentation.
Q: | Is it possible to configure callback with FLI4L?
A: | Yes; see documentation.
Q: | Spec. games/chats/telephone systems in the internet need the so called port forwarding when IP masquerading. Will that be supported in FLI4L ?
A: | From FLI4L version 1.4 there are modules for irc, icq, raudio, etc. additional to the one for ftp. Additionally it is possible to use program ipmasqadm for creation of tables for IP forwarding. See also: portfw FAQ.
Q: | Is it possible to connect a laptop/notebook computer or any other computer without a network adaptor to the FLI4L router to surf/mail using the internet?
A: | Yes; via COM port using PPP or cros-over cable. Search in readme.txt/documentation for OPT_PPP.
Q: | Is FLI4L able to act as a DNS server ?
A: | Yes; operating FLI4L as a DNS server is the recommended use. Reason for this: see documentation.
Q: | May I use FLI4L as printer server ?
A: | Yes; from version 1.4. It is possible to print by using Samba (i.e.: SMB protocol) or lpr/lpd. But: you will need at least 16 MB, better 20 MB of RAM in your FLI4L router.
Q: | Does FLI4L include a DHCP server?
A: | Yes; see documentation.
Q: | Will I be able to use FLI4L for ADSL/SDSL ?
A: | Yes; if the provider offers a real TCP/IP router. If itīs a so called DSL modem...see next question.
Q: | Can I use FLI4L for T-DSL by T-Online ?
A: | Yes; you will need PPPoE (PPP over Ethernet), since Telekom will only give you a so called DSL modem. This will include an Ethernet interface but will use PPP over Ethernet as protocol.
Q: | Will I be able to reach my "old" mail box via ISDN which does not support TCP/IP ?
A: | Yes; by using the ISDN modem emulator package by Christoph Peus. This will enable FLI4L to act - after having connected your PC via COM port - like an ISDN modem. This package is included in FLI4L distribution. Search for OPT_IMODEM
Q: | I didnīt connect a monitor to my FLI4L router. Is it possible to display a connection and the ISDN transfer rates directly on the router ?
A: | Yes; to do so please use the LC display package by Jürgen Bauer. This package is included in the FLI4L distribution. Search for OPT_LCD in readme.txt/documentation.
Q: | Will I be able to add extensions to FLI4L on my own ?
A: | Yes; if you own a working Linux installation. You will find more and detailed information in the documentation and in src/README.
Q: | Will I be able to use FLI4L as an answering machine (telephone) ?
A: | Yes; vbox - as answering machine - is available as OPT package in FLI4L.
Q: | Is it possible to use floppy disks with higher density than 1.44 MB ?
A: | Yes; File mkfloppy.bat must be then used with option -h . But: there will be more read/write errors than there are with 1.44 MB floppy disks.
Q: | Why is today - Monday, Jan 1st 2001 - the circuit of yesterday (Sunday) used ?
A: | Because FLI4L knows holidays.
Q: | How can I set time automatically on a Windows client during start-up ?
A: | Create a new short-cut in Autostart folder of Windows. Command line will be: C:\Windows\NET.EXE time \\fli4l /set /yes. (this is an example; it is possible that you might have to set the correct path) AND "close" on exiting the application.
Q: | How can a driver be included to the start floppy disk ?
A: | All tools that are necessary to do so can be found in: fli4l-x/src/README.
Q: | Does FLI4L offer the opportunity to route between two Ethernets ?
A: | This option exists from version 1.5; it is also possible to do routing for Ethernet / Token Ring.
Q: | Is it correct that FLI4L 1.5 will at least need 12 MB RAM ?
A: | No; under www.fli4l.de there are rootfs images with 2.5 MB RAM disk for 8 MB RAM and with 8 MB RAM disk for (min.) 24 MB RAM (enough space for almost all OPT packages).
Q: | I installed OPT package Junkbuster. Now I want to enable spec. clients to access the internet only through this proxy. How do I have to configure FLI4L for this ?
A: | Enter the client(s) in FORWARD_DENY_HOST_X; then surfing the internet will only be possible via your proxy.
Q: | What do I have to do, if I want to keep a page (IP) at dtdns at actual values ?
A: | See Mini Howto for IP actualisation on a HTML page by Carl Kossack, the OPT_DTDNS package (under AddON on FLI4Līs homepage) by Jens Fischer and DynDNS providers by Tobias Gruetzmacher.
