Intrusion Detection System; Ping; Mac Filtering; Ip Filtering - Hitron CGN2 User Manual

4.1.2

INTRUSION DETECTION SYSTEM

An intrusion detection system monitors network activity, looking for policy violations,
and malicious or suspicious activity. The CGN2's intrusion detection system logs all
such activity to the Firewall > Local Logs screen.
4.1.3

PING

The CGN2 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

MAC FILTERING

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 CGN2'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 CGN2 and the network (in which case

all other devices can access the network)
or
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

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 CGN2 discards outgoing data packets that match the criteria you
specified.
