If you're a small business owner looking for a reliable email server, a curious Windows administrator, or if you just want to put that old computer in the closet to work, you'll learn how to get things up and running quickly.

This book is a guide to FreeBSD for network administrators; therefore it does not cover basic installation and configuration of FreeBSD, but is about using FreeBSD to build, secure, and maintain networks. After introducing the basic tools for monitoring the performance and security of the system the book moves on to cover using jails-FreeBSD virtual environments-to secure your network. Then it shows how to overcome the different bottlenecks that you may meet depending on the services you are running by tweaking different parameters to maintain a high performance from your FreeBSD server. Next it covers using the ifconfig utility to configure interfaces with different layer protocols and about connectivity testing and debugging tools. After covering using User PPP or Kernel PPP for Point-to-Point Protocol network configuration it explains basic IP forwarding in FreeBSD and the use of the built-in routing daemons, routed and route6d, which support RIPv1, RIPv2, RIPng, and RDISC. Next it covers the OpenOSPFD and OpenBGPD daemons that you can install to run OSPF and BGP on your host. Then it covers setup and configuration of IPFW and PF, and finally looks at some important internet services and how to set them up on your FreeBSD server.
