A VSX Gateway is a physical machine that hosts virtual "networks", consisting of Virtual Devices that provide the functionality of their physical network counterparts such as: Security Gateways, routers and switches.

A VSX Gateway performs the following tasks:

• Communicates with the management server to handle provisioning and configuration for all Virtual Devices
• Manages state synchronization for High Availability and for Load Sharing in cluster deployments.

Management Server Connections

A management server (Security Management Server or Multi-Domain Server) connects to the VSX Gateway and provides provisioning and configuration services for Virtual Devices located on the VSX Gateway. You can connect the management server to the VSX Gateway using one of the following scenarios.

• Local Connection: The management server connects directly to the VSX Gateway using a dedicated management interface.
• Remote Connection: The management server connects remotely from an external or internal network by means of a router connected to a management interface. This method ensures segregation of management traffic from all other traffic.
