Checkpoint 156-215.81 Based on Real Exam Environment

Gaia can be managed through CLI, WebUI, and SmartDashboard1, p. 17-18. CLI is a command-line interface that allows administrators to configure and monitor Gaia using commands and scripts. WebUI is a web-based interface that allows administrators to configure and monitor Gaia using a browser. SmartDashboard is a graphical user interface that allows administrators to manage security policies and objects for Gaia devices.

The CDT utility supports all upgrades, including major version upgrades, Jumbo HFA’s, and hotfixes3. References: Check Point Upgrade Service Engine (CPUSE) - Gaia Deployment Agent

If the NAT property ‘Translate destination on client side’ is not enabled in Global properties, nothing needs to be configured on the client side, because the Gateway takes care of all details necessary. The Gateway translates the destination IP address before sending the packet to the client, so the client does not need to know about the NAT rule or add any host route or ARP entry.

NAT (Network Address Translation) is a technique that modifies the IP addresses or ports of packets that pass through a security gateway. NAT can be configured in two ways: Automatic or Manual. Automatic NAT means that the NAT rules are generated automatically by the security gateway based on the NAT properties of network objects. Manual NAT means that the NAT rules are defined explicitly by the administrator in the NAT policy. Proxy ARP (Address Resolution Protocol) is a technique that allows a security gateway to answer ARP requests on behalf of other hosts. Proxy ARP is needed when a host on one network segment tries to communicate with a host on another network segment that has a different IP address than its own. In some scenarios, an administrator will need to manually define Proxy ARP for NAT to work properly. One such scenario is when they configure a Manual Static NAT which translates to an IP address that does not belong to one of the firewall’s interfaces2.
