VPN Gateways

A VPN gateway can be embodied in software on a server, an enhancement to a router or firewall, or a security appliance. A VPN gateway handles the high-speed encryption/decryption, negotiates the SAs (Security Associations), provides tunneling services, and generally makes sure things get done to make a VPN connection.

The data processing requirements for running a VPN are high because of the heavy demands of encrypting and decrypting data as it passes through the VPN gateway. Because of these demands, choosing a VPN gateway that can handle the load is an important factor in deciding on a VPN solution.

The better VPN solutions use a dedicated security device or appliance that offloads the VPN and Internet security processing off a computer or router and puts it on a platform with a high-performance processor designed for high-demand data processing. An Internet security appliance is a standalone hardware platform that sits between the public and private networks to prevent unauthorized intrusions into the private network and acts as the VPN gateway.

SonicWALL VPN appliances are high performance, hardware-based security platforms that provide support for an expanding array of security services. All SonicWALL appliances include these features:

Reassembly-Free Deep Packet Inspection (RFDPI) At the heart of every SonicWALL network security solution is their patented RFDPI engine. SonicWALL’s pioneering RFDPI technology unifies multiple security products into a single integrated suite, enabling administrators to manage local, remote and mobile network security simply and cost-effectively. RFDPI increases productivity by allowing IT to create reusable and adaptive policy control. More than simply a security approach, RFDPI incorporates object-based contextual controls over user identity and access; application identity and access; data leakage; network optimization; as well as granular reporting, auditing and forensics.

IP Address Management SonicWALL VPN appliances include built in NAT (Network Address Translation) and DHCP (Dynamic Host Configuration Protocol) features that enable remote offices to be integrated into the organization’s network and allow offices with multiple PCs to share broadband connections.

Ease of Management and Administration SonicWALL VPN appliances are designed for easy setup and administration using a streamlined Web-based interface. They can also be managed remotely from a central location using the Global Management System.

SonicOS Utilizing the new SonicOS operating system, SonicWALL appliances offer a choice between absolute ease of use for basic networks and ultimate flexibility for more complex networks. SonicOS Standard, allows rapid deployment in basic networks with a user-friendly Web interface and powerful wizards. SonicOS Enhanced is an optional software upgrade that builds upon SonicOS Standard to deliver advanced features for more complex network installations.

High Performance, Scalable Hardware Architecture SonicWALL’s robust architecture based on powerful RISC processors supports throughput rates of over 100 Mbps allowing maximum performance of your network. In addition, the appliances utilize a solid-state design with no moving parts, which increases reliability and reduces downtime.

VPN Single-Arm Mode Enables a SonicWALL appliance to connect to a WAN interface on a subnet with an existing firewall and process all VPN traffic, removing the burden of encryption/decryption from the firewall protecting the Internet connections.

RIP Advertising RIP Advertising dynamically advertises updated VPN and static routing information to the internal network ensuring reliable connectivity to the critical resources. RIPv1 and RIPv2 are supported.

AES Support Support for the Advanced Encryption Standard (AES), an encryption algorithm in the process of emerging as the de facto encryption standard.
