Many decisions need to be made before we can begin to configure the network interfaces. These can be, and in fact normally are, both complex and highly dependent upon many “local” factors. Some of these are listed below:
Are the systems located in separate buildings or connected to different physical networks, requiring hardware to bridge them?
