Linux box as Gateway to internet for Windows Network
 
I have Microsoft network of 20 windows 2000 prof clients and 2 windows 2000 server; 1 server as Domain Controller and another has broadband connection with 2 NIC. One NIC connects to Broadband and another to LAN.

Now im planning to use linux server for the place of second pc with broadband conenectio. Do u think its a good idea interms of security? Will i be able to share the internet connections. What about the viruses?

i'd suggest using linux as a dedicated firewall and gateway server:

http://ipcop.org
http://smoothwall.org

Take a look at www.smoothwall.org

In term of security and stability it is a very good choice to have a linux box serving as a router/gateway.
Tough there are not a lot of viruses for linux, there are many for Windows. This means you will still have to run AV software on the windows machines. In my opinion it's not really necessary to run AV software on a linux box. But if you want some extra protection, it can't hurt.

oh these firewall systems... they are linux still. you can install other programs, such as netowrk virus scanners, on them while still being a firewall. i run ntop (.org) on my ipcop box for example.

I have looked at smoothwall & ipcop, they seems perfect solution. By the way ive been using a internet management software called Winproxy, is there any for Linux with which i can manage internet conenctions like which pc can access which cannot, managing access of http, ftp, and all.

acid_kewpie 11-26-2004 08:30 AM

you can open certain port acces based on IP within either ipcop or SW (ipcop is a fork of and old SW 1.0 release).

note that these are not strictly proxies, just routing firewalls, much mcuh more straightforward and direct. I think that the commerical versions of SW including squid attachments if you did want to proxy too.. not really needed though. either of these two can deny http traffic to certain machines with little hassle.

i use squid proxy as transperantly. actually i dont use disrtos which are desinged as firewall. i use redhat and prefer to modify it for my network requests. if u r a beginner, firewall distros are good choice for u. they have good and easy web interfaces.

i tried some solutions such as winproxy, wingate, M$ ISA on windows side before. but noone of them were good enough. actually they are nothing against linux based solutions.

addationally u can prefer squidguard(.org) with squid to block most of adware porno warez sites (over 100.000). u may prefer dansguardian(.org) instead of squidguard. most of firewall distro comes with dansguardian or similar softwares already. redwall(.sourceforge.net) is an another firewall distro. u have lots of choices in linux world.

I use squid too on a Redhat 9 box and it has always served my network well! The stability of of the program is good and I usually don't have any problems.

bickyz 11-28-2004 05:32 AM

I vee looked at squidguard, redwall, dansguardian. They seems to be configured from command based, is there any GUI based? Will be much easier..

maxut 11-29-2004 04:04 AM

sorry i wasnt clear enough. squidguard and dansguardian are programs which works with squid. they r not distro.

redwall is a firewall distro which includes squid, dansguardian, vpn, firewall and much more. i didnt try redwall nor smothwall. i tried astaro(.com) (commercial firewall distro) for testing. most (maybe all) of firewall distros have easy web interface for remote configuration. just get one (or more) of them. install it to test box. and see what it is. do not install it to any computer which is used. if u dont have a test box, backup all of data before starting.

good luck.

I use smoothwall to protect a netwok of seven other computers running Win98 / mandy 10. I am seriously thinking of switching to IP Cop though.
I am going to run a computer in server-only mode, that will use SME Server 6.0.
Linux firewalls are great, generally easy to set up and quite reliable. And can run on older equipment, Astaro needs a bigger HDD than the others though.

good luck
live long and prosper
