As we discussed in previous chapters, IPCop has a color scheme for referencing the NICs installed in the system. This is the first point in the installation process where we encounter these.

The Green interface corresponds to our local network and we can select this interface now. The simplest method is to allow IPCop to Probe for the network card, which it completes very reliably. If, however, we know exactly which make and model of card we want to use, we can choose to Select it manually which will then provide us with a list of known cards to choose from.
