Gigabit Content Security Router User’s Manual

3.2 Security router Network Connection

The device has 4 WAN ports and a hardware DMZ port; therefore, users can connect the device to the

Internet, and configure a connection to a Public IP server at the same time.

WAN connection

：

A WAN port can be connected with xDSL Modem, Fiber Modem, Switching Hub, or

through an external router to connect to the Internet.

LAN Connection:

The LAN port can be connected to a Switching Hub or directly to a PC. Users can

use servers for monitoring or filtering through the port after “Physical Port Management” configuration
is done.
