Thread: Server Firewall?

I have to make all the Network Traffic go by a Gentoo Box with Iptables.
But I have no idea what to Google to find information about how to do that..
So basicly the system is like this:
Inet - Zywall - Webserver - <GENTOO, This one> - MicroSoft SBS - Desktops
How can I setup that Gentoo box?
What do I have to Google?
Since I really have no idea..
WhooWhoo I think I nearly control IPtables now.. ^^
Though I can only edit the Config File :P I know I shouldnt change it in that way.
But hey it works. And I understand it.. So what the
I still have a couple of Questions about it though.
Id like to know if there is a Certificate like "Certificated iptables Technician" or a Good book about it. Since well I understand how it works and stuff. But I know for sure there are some cool tricks I dont know yet. (Like putting the Always - Drop as last Rule in every chain )
Also Id like to know were the Logs are Saved?
Since there isnt a iptables file in the /var/log/ dirs.
Oh and when I open the config file I see the names of the chains eg. INPUT [0:0] what does the [0:0] mean? And I also like to know if there is a way to Filter Destination MAC adres. Since I have no clue how to do that. And when i google for that I get something that just doesnt work.. (eg. iptables -A INPUT -m mac --mac-source 00:0F:EA:91:04:08 -j DROP)
And well I still have my first problem. The one with the netting. I think I have to do that with Redirecting or something but I really have no idea how to google for the problem..
Well, is there anyone who can answer nearly all my Questions?
Or knows a good online Tutorial? Or a Book or a course about IPtables?
Since this one is really good.. ^^

Not sure i understand your question.
Routing comes to mind when passing packets from one interface/host o another.

I not a linux pro but as far as I know the term is Dual Subnet.
After googling abit and stuff I think its called NAT and not Dual Subnet.
Dual Subnet. is that you have a Diffrent Subnet on two sides right?
NAT is sharing one IP with eachother so thats not what I really want aswell.
So, well I want to do the following thing:
(WAN) Wire -> NIC (Eth0) -> IPtables Filtering Junk Out -> NIC (Eth1) -> Wire (LAN)
(I know its kinda offtopic but while reading I also got intrested into Squid. Is there also such a great tutorial of?)
