4.1.2

INTRUSION DETECTION SYSTEM

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

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

such activity to the Firewall > Local Logs screen.

4.1.3

The CGN allows you to use the ping utility on the LAN (in the WAN/LAN > Debug

screen) and also on the WAN (in the Firewall > Firewall Options screen). For more

information, see

Debugging (Ping and Traceroute)

4.1.4

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

identifies it on the network. When you enable MAC address filtering on the CGN's

firewall, you can set up a list of MAC addresses, and then specify whether you want

to:



Deny the devices on the list access to the CGN 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)

4.1.5

IP filtering allows you to prevent computers on the LAN from sending certain types of

data to the WAN. You can use this to prevent unwanted outgoing communications.

Specify the IP address of the computer on the LAN from which you want to prevent

communications, and specify the port range of the communications you want to

prevent. The CGN discards outgoing data packets that match the criteria you

specified.
