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.

Chapter 5 – Network Address Translation

  1. Classless networks (CIDR), private networks (RFC 1918 networks), and IPv6. Any two would be acceptable.
  2. No; we do not need to alter the Outbound NAT settings because outbound NAT rules were generated for each of the non-WAN interfaces.
  3. Two rules (one for IPsec and the other for all other traffic).
  4. 1:1 NAT.
  5. The port forwarding traffic will be blocked by the firewall.
  6. We normally don’t care what the source of the incoming traffic is.
  7. (a) 7000; (b) 3389.
  8. (a) Multihoming and route aggregation are both valid answers. (b) DHCPv6.
