Introduction

The VSX Virtual System Extension. Check Point virtual networking solution, hosted on a computer or cluster with virtual abstractions of Check Point Security Gateways and other network devices. These Virtual Devices provide the same functionality as their physical counterparts. Administration Guide describes the Virtual System eXtension product that runs several virtual firewalls on the same hardware.

Each Virtual System works as a Security Gateway Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources., typically protecting a specified network. When packets arrive at the VSX Gateway Physical server that hosts VSX virtual networks, including all Virtual Devices that provide the functionality of physical network devices. It holds at least one Virtual System, which is called VS0., it sends traffic to the Virtual System Virtual Device on a VSX Gateway or VSX Cluster Member that implements the functionality of a Security Gateway. Acronym: VS. protecting the destination network. The Virtual System inspects all traffic and allows or rejects it according to rules defined in the security policy Collection of rules that control network traffic and enforce organization guidelines for data protection and access to resources with packet inspection..

In order to better understand how virtual networks work, it is important to compare physical network environments with their virtual (VSX) counterparts. While physical networks consist of many hardware components, VSX virtual networks reside on a single configurable VSX Gateway or cluster Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing. that defines and protects multiple independent networks, together with their virtual components.

Example Physical Network Topology

In a typical deployment with multiple Security Gateways, each protects a separate network.

Each physical Security Gateway has interfaces to the perimeter router and to the network it protects.

Example VSX Virtual Network Topology

Deploy one VSX Gateway with four Virtual Systems to protect multiple networks.

3	VSX Gateway. Each Virtual System in a VSX environment is a Security Gateway, with the same security and networking functionality as a physical gateway. Each handles packet traffic to and from the one network it protects.
4	Warp Links. Virtual interfaces and network cables connect the Virtual Systems and the Virtual Switch Virtual Device on a VSX Gateway or VSX Cluster Member that functions as a physical switch. Acronym: VSW..
5	Virtual Switch. Connects all the Virtual Systems to the Internet router.
