3.2. Placement of the firewall/router in a Skolelinux/Debian-edu Network[id=coyoteplacement]
 | Although I keep mentioning the necessary firewall/router and Coyote Linux in the same sentences, that doesn't mean that you must use Coyote Linux for this purpose. You can use a dedicated router from any commercial manufacturer you like, or something similar to Coyote Linux such as FloppyFirewall, Gibraltar. It's just that I personally prefer Coyote Linux. You must just remember that whatever firewall/router you use, it must be configured like A |
The firewall/router has a defined role in the Skolelinux/Debian-edu network. Without it, the network will not function optimally.
Coyote Linux has two network cards, each having different roles. One network card is to be connected to the existing network, so that it gets connected to the Internet. In Coyote Linux, this network interface is called WAN, eth1, Internet. The other card, which is to be connected to your Skolelinux/Debian-edu network is called LAN, eth0, LAN network. This card is connected either directly to the Skolelinux/Debian-edu mainserver with a crossover cable (for small networks), or via a switch making a so-called 10.0.2/23-backbone network.
 | Don't mix up the different roles of eth0 and eth1 in Coyote Linux and Skolelinux/Debian-edu |
A similar diagram with an overview of a complete Skolelinux/Debian-edu network is available in Section 4.1
