Easily manage all aspects of the network from a single interface. Each port on the SonicWALL Firewall can be divided into zones that are separated from the other. By also dividing a connected managed switch, we can isolate systems into different networks. There are multiple options of external managed switches that can be connected to the SonicWALL management interface. In this example, the top image is the SonicWALL TZ350 Firewall divided into zones, including:

    • X0 - Local Area Network
    • X1 - Internet Connection
    • X2 - Wireless Networks - Virtual Access Points (VAP)
      • X2:V2 - Public VAP
      • X2:V3 - Private VAP
      • X2:V4 - TV VAP
      • X2:V5 - Tenant VAP
    • X3 - Security Cameras
    • X4 - Streaming Music

The Connected Switch is divided into Virtual Local Area Networks (VLANs) & linked directly from the SonicWALL Firewall & then on out to endpoints on the individual networks.

Dynamic DNS

Dynamic DNS

Dynamic DNS

Dyn DNS enables Access Control as well as Internet Connectivity by using Fully Qualified Domain Names, even behind Dynamic IP address connections. Host Names are setup for:

    • Remote connectivity to network devices
    • Authentication of Remote access authorization

As a leading Dynamic DNS provider, Oracle allows you to choose a unique hostname (ex: and link it to any IP-compatible device (router, webcam, security camera, DVR, thermostat, computer, file storage, etc.). As the IP addresses used to access these devices change, Oracle takes care of updating it for you, ensuring you are always connected.

Site to Site VPN

Site to Site VPN

Site to Site VPN

A Virtual Private Network (VPN) provides a secure connection between two or more computers or protected networks over the public Internet. It provides authentication to ensure that the information is going to and from the correct parties. It also offers security to protect the data from viewing or tampering en route.

A VPN is created by establishing a secure tunnel through the Internet. This tunnel is a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption. It is flexible in that you can change it at any time to add more nodes, change the nodes, or remove them altogether. VPN is less costly, because it uses the existing Internet infrastructure.

VPNs can support either remote access—connecting a user’s computer to a corporate network—or site to site, which is connecting two networks. A VPN can also be used to interconnect two similar networks over a dissimilar middle network: for example, two IPv6 networks connecting over an IPv4 network.

SSL VPN - Secured Remote Access

SSL VPN - Secured Remote Access

SSL Virtual Office

SSL VPN - Secured Remote Access

NetExtender is an SSL VPN client for Windows, Mac or Linux users that is downloaded transparently and that allows you to run any application securely on the company's network. It uses Point-to-Point Protocol (PPP). NetExtender allows remote clients seamless access to resources on your local network. Users can access NetExtender two ways:

  • Logging in to the Virtual Office web portal provided by the SonicWall security appliance and clicking on the NetExtender button.
  • Launching the standalone NetExtender client.

The NetExtender standalone client is installed the first time you launch NetExtender. Thereafter, it can be accessed directly from the Start menu on Windows systems, from the Application folder or dock on MacOS systems, or by the path name or from the shortcut bar on Linux systems.

NetExtender provides remote users with full access to your protected internal network. The experience is virtually identical to that of using a traditional IPSec VPN client, but NetExtender does not require any manual client installation. Instead, the NetExtender Windows client is automatically installed on a remote user's PC by an ActiveX control when using the Internet Explorer browser, or with the XPCOM plugin when using Firefox.

On MacOS systems, supported browsers use Java controls to automatically install NetExtender from the Virtual Office portal. Linux systems can also install and use the NetExtender client.

After installation, NetExtender automatically launches and connects a virtual adapter for secure SSL-VPN point-to-point access to permitted hosts and subnets on the internal network.



DPI-SSL Categories


Deep Packet Inspection over Secure Socket Layer DPI-SSL

Deep Packet Inspection of Secure Socket Layer (DPI-SSL) extends SonicWall’s Deep Packet Inspection technology to the inspection of encrypted HTTPS traffic and other SSL-based traffic. The SSL traffic is decrypted (intercepted) transparently, scanned for threats, and then re-encrypted and, if no threats or vulnerabilities are found, sent along to its destination.

DPI-SSL provides additional security, application control, and data-leakage prevention for analyzing encrypted HTTPS and other SSL-based traffic. DPI-SSL supports:

    • Transport Layer Security (TLS) Handshake Protocol 1.2 and earlier versions – Starting with SonicOS, the TLS 1.2 communication protocol is supported during SSL inspection/decryption between the firewall and the server in DPI-SSL deployments (previously, TLS 1.2 was only supported between client and firewall). SonicOS also supports TLS 1.2 in other areas as well.
    • SHA-256 – All re-signed server certificates are signed with the SHA-256 hash algorithm.
    • Perfect Forward Secrecy (PFS) – Perfect Forward Secrecy-based ciphers and other stronger ciphers are prioritized over weak ciphers in the advertised cipher suite. As a result, the client or server is not expected to negotiate a weak cipher unless the client or server does not support a strong cipher.

DPI-SSL also supports application-level Bandwidth Management over SSL tunnels. App Rules HTTP bandwidth management policies also applies to content that is accessed over HTTPS when DPI-SSL is enabled for App Rules.

Security Camera Remote Access

Many businesses need security camera recorder systems & want to be able to view camera activity remotely or receive alerts on mobile devices about alerts & events. The SonicWALL Firewall is able to connect these security cameras to mobile / remote devices for secured remote access & administration.

By creating a separate Zone in the SonicWALL, we can isolate the security recorder network from Local Area Network Computers & other Zones. Firewall Access Control Policies can be created to allow or deny Internet access on a granular level.
