A new window will appear concerning the network configuration that looks like this :

This is where you need to select the network card which will be used for the green interface. Once this network card has been detected it will ask you to specify a private address:  This address corresponds to the Gateway of the client computers on the green network.

Note: It is recommended to perform a search before manually selecting a network card in the list (remember: cards from X that are based on chipsets from Y that are recognized as Y branded cards under Windows are to be avoided).

Select the IP address of the green interface, for example 192.168.1.1:

A message will be displayed indicating that IPCop has been successfully installed on your computer and that your CD should be removed from the drive, once ejected press [Enter].

The system will restart and the installation will finish by asking you the keyboard that is currently installed on your system. For French you should select “fr-latin1” then [OK], next select “Europe/Paris” as your time zone (if you live in France).

A host name will be asked for which will correspond to the IPCop server name, then a domain name (leave “localdomain” if you don’t have one).

You will then arrive at the configuration of your modem step (if you have one):

  • If you are currently using a modem to connect your computer to the Internet, you can connect it directly to IPCop. If you are going to use a device of this type then it is best to select the device from the available list (“*AUTODETECT*” makes it possible to simplify the search process), to then activate the modem continue the installation with the corresponding button.  Your modem will then be defined as the red interface.
  • If you don’t intend to use a modem, select “deactivate RNIS (ISDN)” to continue the installation. One of your network cards will automatically be designated as the red zone interface during the installation process.
