  There are two network cards in Coyote Linux, one (LAN) is connected to the Skolelinux/Debian-edu server, the other is connected with a crossed cable, or via a switch to another network (WAN). Sometimes it can be a bit difficult to decide which network card is which, especially if they are both connected to the same address. The method we use to determine which card is which, is to use a crossed cable and connect it to the network card in the Skolelinux/Debian-edu main server.
