Louie,

If you would like to see a few different DMZ configurations, please visit my website : www.firewall.cx 

Under the "Firewalls" menu you will find the DMZ topic.

Also, under 'Firewalls-->NAT-->Static NAT--> Concepts and Examples' you will find a nice DMZ example to help you, should you decide to implement it.

Cheers,

Chris P.

I currently have a project to make a DMZ farm of servers. I actually want to
make this firewall
be splitted in to 4 or more networks. I'll be trying to host 3 different
company, I would like to
try using Iptables as my main firewall and gateway before the internet.

Could this be done? And which documents should i read? I currently have a
different network that i am masquerading right now. But i had never tried a
dmz type that is so complicated yet for me.

Hope i could have feedback on my problem!

..piece of cake, several ways:  http://ipcop.org/  needs its 
own box, http://shorewall.net/ does really does too in your 
case, add in http://webmin.com/ to control it too, from a web 
browser, or, you can control both from ssh.

I personally would avoid ipcop because the last time I checked it was
still 2.2 based and was not a stateful firewall.  I can't speak for
shorewall, I haven't had a chance to play with it yet (we wrote our own
firewall code + web interface so I haven't kept up too much on some of
these other projects).

..ipcop-0.1.1 thru 1.2.0 are 2.2/ipchains and _not_ stateful, 
1.3 upwards is 2.4/iptables and stateful, just like shorewall.  
For production requiring statefulness, you want shorewall, 
until ipcop-1.3beta1 is found demonstrably stable.

..ah, time to back off on the panting and _take_ that time.  ;-)

You might take a look at Shorewall (http://www.shorewall.net) -- it makes 
setting up these types of configurations much easier than it would be by 
hand. Start with http://www.shorewall.net/shorewall_setup_guide.htm to get 
an idea of your options. While that document describes just a 
three-interface firewall with DMZ, extending it to include more networks is 
straightforward.
