Mastering pfSense - Second Edition

By: David Zientara

Overview of this book

pfSense has the same reliability and stability as even the most popular commercial firewall offerings on the market – but, like the very best open-source software, it doesn’t limit you. You’re in control – you can exploit and customize pfSense around your security needs. Mastering pfSense - Second Edition, covers features that have long been part of pfSense such as captive portal, VLANs, traffic shaping, VPNs, load balancing, Common Address Redundancy Protocol (CARP), multi-WAN, and routing. It also covers features that have been added with the release of 2.4, such as support for ZFS partitions and OpenVPN 2.4. This book takes into account the fact that, in order to support increased cryptographic loads, pfSense version 2.5 will require a CPU that supports AES-NI. The second edition of this book places more of an emphasis on the practical side of utilizing pfSense than the previous edition, and, as a result, more examples are provided which show in step-by-step fashion how to implement many features.

Server load balancing

Configuring server load balancing in pfSense involves two steps. First, you must create one or more virtual-server pools. Second, you must create one or more virtual server (the server to which clients will actually connect).

To begin server load balancing configuration, navigate to Services | Load Balancer. There are four tabs available: Pools, Virtual Servers, Monitors, and Settings. Configuration begins on the Pools tab; on this tab, click on the Add button to add a server pool.

On the pool configuration page, enter an appropriate name in the Name edit box. The next field is the Mode drop-down box; the choices are as follows:

  • Load Balancing: This will balance the load across all servers in the pool
  • Failover: The first server in the pool is used unless it fails; then it fails over to other servers in the pool
