Intranet - Dell SonicWALL GX250 Manual

Intranet

The SonicWALL may 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 need to 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 net-
work 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 GX250 and SonicWALL
GX650, press the Power Switch to the ON position.
