Intrusion detection system

An intrusion detection system monitors network activity, looking for policy violations,

and malicious or suspicious activity. The CGNV's intrusion detection system logs all

such activity to the Security > Logs screen.

7.1.3

Every networking device has a unique Media Access Control (MAC) address that

uniquely identifies it on the network. When you enable MAC address filtering on the

CGNV's firewall, you can set up a list of devices, identified by their MAC addresses,

and then specify whether you want to:

Deny the devices on the list access to the CGNV and the network (in which case

all other devices can access the network)

Allow the devices on the list to access the network (in which case no other

devices can access the network).

7.1.4

Service filtering is a way of preventing users on the LAN from connecting with devices

on the WAN via specific services, protocols or applications. It achieves this by

permitting or denying traffic from the LAN to pass to the WAN, based on the target

port.

7.2

Use this screen to turn firewall features on or off and to allow or permit certain

applications and protocols. You can select the level of firewall protection from pre-

defined options, or create a custom protection profile.

NOTE:

To block specific ports, use the Service Filter screen (see
