How Mobile Connect Works

Modern business practices increasingly require that users be able to access any network resource (files, internal websites, and so on), anytime, anywhere. At the same time, ensuring the security of these resources is a constant struggle. While most users are aware that they must protect PCs from network security risks, this security awareness does not always extend to Chrome OS devices like the Dell Chromebook 11. And yet, Chromebooks are increasingly being used in enterprises and academic institutions. Furthermore, remote Chromebook users can often use insecure, untrusted, public Wi-Fi hot spots to connect to the Internet. It is therefore a challenge to provide secure, mobile access while still guarding against the inherent security risks faced by mobile users.

The SonicWall Mobile Connect for Chrome OS app provides secure, mobile access to sensitive network resources. Mobile Connect establishes a Secure Socket Layer Virtual Private Network (SSL VPN) connection to private networks that are protected by SonicWall security appliances. All traffic to and from the private network is securely transmitted over the SSL VPN tunnel.

After installing SonicWall Mobile Connect from the Chrome Web Store, to get started with Mobile Connect:

1
Ensure that the SonicWall SMA or firewall appliance being used by Mobile Connect is connected to the network.
2
Configure Network Information (server name, username, password, and so on).
3
Mobile Connect establishes a SSL VPN tunnel to the SonicWall security appliance.
4
You can now access resources on the private network. All traffic to and from the private network is securely transmitted over the SSL VPN tunnel.

SonicWall Appliance Support

SonicWall Mobile Connect is a free app, but requires a concurrent user license on one of the following SonicWall solutions in order to function properly:

SonicWall firewall appliances including the TZ, NSA, E-Class NSA, and SuperMassive™ 9000 Series running SonicOS 5.8.1.0 or higher
SonicWall Secure Mobile Access 100 Series / SRA appliances running 7.5 or higher

Required Network Information

To use Mobile Connect, you need the following information from your network administrator or IT Support:

Server name or address - This is either the IP address or URL of the SSL VPN server to which you are connecting.
Username and password - Typically, you are required to enter your username and password, although some connections might not require this.
Domain name - The domain name of the SSL VPN server. Mobile Connect might be able to automatically determine this when it first contacts the server, or there could be multiple domains that can be selected.

DNS Domain Settings on Appliances

Before Mobile Connect users are able to access the private network, the network administrator must configure the DNS Domain on the SonicWall appliance. When the Mobile Connect user accesses a URL on the private network, the configured DNS domain is used to resolve the hostname lookup. For public domains that do not match the configured DNS domain, the DNS server for the Wi-Fi or cellular network is used.

NOTE: The Mobile Connect user does not need to perform any configuration tasks related to DNS. The following information is for SonicWall network administrators.
