Configuring Intranet Settings
Network > Intranet
The SonicWALL security appliance can be configured as an Intranet firewall to prevent network users 
from accessing sensitive servers. By default, users on your LAN can access the Internet router, but 
not devices connected to the WAN port of the SonicWALL security appliance. To enable access to the 
area between the SonicWALL security appliance WAN port and the Internet, you must configure the 
Intranet settings on the SonicWALL security appliance on the Network > Intranet page.
Intranet firewalling is achieved by connecting the SonicWALL security appliance between an 
unprotected and a protected segment, as shown below.
