Mandrake 9.1 as firewall

PetarS · 07-19-2003, 03:07 PM

Hi, I'm very new with Linux so I have few questions about it
1. Can I, as I've been told to, install and set up Mandrake 9.1 for firewall (internet server-gateway) ?
2. Is it neccesary to start KDE desktop? Or, can I have it running in some "lighter" mode?
3. Where can I find some quick instructions to do these things?
- General idea is to have a Windows based network with internet access trough Linux base firewall- If you have any suggestions, I'll be glad to hear them

THANKS

Can I, as I've been told to, install and set up Mandrake 9.1 for firewall (internet server-gateway) ?
Yes, you will to active IP forwarding and masquerading and learn to use iptables. There are GUI tools that can help you setup a firewall in Linux.

Is it neccesary to start KDE desktop? Or, can I have it running in some "lighter" mode?
There are many different Desktops available for Linux (KDE, GNOME, Ximian, IceWin, WindowMaker, etc)

Where can I find some quick instructions to do these things?
If you do a search on LQ, you will find many threads concerning iptables, ip masquerading and firewalls in Linux.

Ok, I'll try that tomorow
I have to set up a modem first, winmodem problems(Shark USB and USR V90 ISA modem) ... Can I use Zoltrix FM336i (older but not a winmodem)?

Yes, I don't see why that modem would not work in Linux.

As for starting up Linux in a "lighter mode", you don't need to boot in a GUI at all. Once the system is set-up as a firewall and internet server, you can have it start in runlevel 3 which is the non-graphical mode.

Ok, thanks, now next question- if for any reason zoltrix won't work, what type of modem should I buy - something that installs easy and linux recognize itself?

Lemme jump in here real quick and ask something...

You are looking for a linux firewall on a dial up network to masquerade/filter/"firewall" your windoze boxes? On a dial up connection?

Just curious...

External modems are nearly guaranteed to work, but you'll pay for em because of that. Check out the hardware section as I'm sure there'll be a few modems mentioned "not" to buy, that'll help narrow it down a bit. Also, check Mandrake's HCL - Hardware Compatibility List as well as redhat's:

With mandrake it shouldn't be much of a problem once you get the drive, but that's really probably an understatement.

Cool

have you thought about using shorewall on your mandrake box?

it rocks.

Well, I've visited HCL site and found out that I will have to buy a new modem, any how, thanks for informations, now I have to check that "shorewall"
