Virtual Firewall

Virtual Firewall

Increasing small-scale private networks have been established. Most of these private networks belong to small-scale enterprises. Such enterprises require high security and cannot afford a private security device.

The device can be divided into multiple virtual firewalls to serve multiple small-scale private networks.

A virtual firewall integrates a VPN instance and a security instance. It provides a private routing plane and security service for the virtual firewall users.

VPN Instance

A VPN instance provides separated VPN routes for the users under a virtual firewall. These VPN routes are used to forward the packets received by a virtual firewall.

Security Instance

A security instance provides separated security services for the users under a virtual firewall. The security instances contain private interfaces, zones, interzones, ACL rules, and NAT rules. They provide the security services such as address binding, blacklist, packet filtering, traffic statistics and monitoring, attack defense, ASPF, and NAT for the users under the virtual firewalls.
