Intro to OpenBSD networking

In contrast to its sysv counterparts like Linux, OpenBSD has a very different way of controlling network interfaces and setting parameters. Other competing systems commonly use menu-based or graphical configuration utilities to make the administrator's life easier. OpenBSD chooses to stray from this, instead focusing their efforts on the functionality and correctness of its networking components. The example being used here is the setup of a gateway machine with one PPP interface and one Ethernet interface.
