Check Point Firewall Administration R81.10+

By: Vladimir Yakovlev

Overview of this book

Check Point firewalls are the premiere firewalls, access control, and threat prevention appliances for physical and virtual infrastructures. With Check Point’s superior security, administrators can help maintain confidentiality, integrity, and the availability of their resources protected by firewalls and threat prevention devices. This hands-on guide covers everything you need to be fluent in using Check Point firewalls for your operations. This book familiarizes you with Check Point firewalls and their most common implementation scenarios, showing you how to deploy them from scratch. You will begin by following the deployment and configuration of Check Point products and advance to their administration for an organization. Once you’ve learned how to plan, prepare, and implement Check Point infrastructure components and grasped the fundamental principles of their operation, you’ll be guided through the creation and modification of access control policies of increasing complexity, as well as the inclusion of additional features. To run your routine operations infallibly, you’ll also learn how to monitor security logs and dashboards. Generating reports detailing current or historical traffic patterns and security incidents is also covered. By the end of this book, you'll have gained the knowledge necessary to implement and comfortably operate Check Point firewalls.

Automatic NAT

Automatic NAT is configured in the properties of objects. Each time NAT is defined in the properties of a gateway/cluster, management server, host, network, or range, several rules for each object are automatically created in the corresponding Automatic Generated Rules sections.

We should bear in mind that since we are working in a single security domain with the common objects database, once NAT has been configured for an object, the corresponding automatic rules will be identical in all the policy packages we might create.

Automatic static NAT

Static NAT refers to the consistent translation of hosts’ original IP addresses into specific addresses. Let’s take a look at a few example implementations next.

One-to-one

Automatic static NAT is defined in a host object and performs one-to-one NAT, translating the actual IP address of the object into the address we would like it to be accessible by from the networks behind different interface(s...
