Overview of this book

Palo Alto Networks’ integrated platform makes it easy to manage network and cloud security along with endpoint protection and a wide range of security services. This book is an end-to-end guide to configure firewalls and deploy them in your network infrastructure. You will see how to quickly set up, configure and understand the technology, and troubleshoot any issues that may occur. This book will serve as your go-to reference for everything from setting up to troubleshooting complex issues. You will learn your way around the web interface and command-line structure, understand how the technology works so you can confidently predict the expected behavior, and successfully troubleshoot any anomalies you may encounter. Finally, you will see how to deploy firewalls in a cloud environment, and special or unique considerations when setting them to protect resources. By the end of this book, for your configuration setup you will instinctively know how to approach challenges, find the resources you need, and solve most issues efficiently.

Setting up the VPN

There are several ways of connecting devices in a secure way.

Palo Alto Networks firewalls currently support the following protocols:

  • Generic Routing Encapsulation (GRE) is a fairly old protocol that is not very secure but can be useful if legacy devices need to be connected to the firewall to provide rudimentary security to the encapsulated packets.
  • Internet Protocol Security (IPSec) is the de facto tunneling protocol between remote sites and can be used for very strong encryption.
  • Secure Socket Layer (SSL), which is really Transport Layer Security (TLS), is used to connect endpoints over a network-friendly protocol.

To set up GRE tunnels, you can set up a connection in Networks | GRE Tunnels. All you need to configure is the following:

  • Name (this can be any description)
  • Source interface
  • Source IP is the IP associated with the source interface
  • Destination IP is the IP for the remote peer
  • Tunnel...
