Setup is simple and straightforward. The device has a default IP address, which is convenient and avoids the need for a serial connection, but might conflict with another device on the network.
As the configuration process involves changing the IP address and subnet mask of the PC used to manage the setup, it is better to set up a separate temporary network to avoid address conflicts. (The vendor said there is a setup tool on the CD which avoids this problem without changing the IP address on the PC).
The device will detect the connectivity mode during setup, but it is advisable to determine how the ISP distributes IP addresses before connecting to the internet. The firewall software is installed in the appliance, and the only software needed on the management PC is a web browser with Java support.
SonicWALL has provided suitable browser software for Mac, Windows and Linux operating systems on the accompanying CD, which also contains the VPN client software, recovery utilities and comprehensive administration documentation. Online help is available through the browser.
The default firewall settings allow access from any machine on the LAN to any address on the internet, while blocking all access from the internet to the LAN. Adding new rules is easy by using either the rule wizard provided or the standard rule-editing routines.
The simple browser interface is deceptive, because there are many advanced options that can be accessed, but the standard facilities are adequate for most purposes. The browser interface gives access to the system's administration and monitoring functions, and allows reporting and alerting processes to be configured. Logs can be sent at predetermined times by email or to a syslog server. Alerts can also be sent to a specified email address.
