Intranet
The SonicWALL 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. To enable access to the area
between the SonicWALL WAN port and the Internet, you must configure the Intranet
settings on the SonicWALL.
Intranet firewalling is achieved by connecting the SonicWALL between an unprotected and
a protected segment, as shown below.
Installation
1. Connect the LAN Ethernet port on the back of the SonicWALL to the network segment
to be protected against unauthorized access.
2. Connect the WAN Ethernet port on the back of the SonicWALL to the rest of the
network.
Note: Devices connected to the WAN port do not have firewall protection. It is
recommended that you use another SonicWALL Internet security appliance to protect
computers on the WAN
.
3. Connect the SonicWALL to a power outlet. For SonicWALL PRO 200 and SonicWALL
PRO 300, press the Power Switch to the ON position.
