You can also protect the router from Denial-of-Service attacks. Denial of Ser-
vice (DoS) attacks are attacks to a computer or network with the objective of
creating as much data traffic as possible and thereby overloading the system.
If DoS protection is enabled using the 'Activate protection against Denial Of
Service' setting, the router, after detecting a DoS attack, discards all corre-
sponding packets.
The Intrusion Detection System (IDS) is used to detect intruders in a computer
or network.
The 'Activate Intrusion Detection System' option lets you configure how the
firewall is to react to a detected intrusion attempt and how it is to deal with
the corresponding packets. The following are your options:
b
'Yes': The packets are discarded without notification.
b 'No': The packets are forwarded.
Additionally, you can instruct the firewall to filter out certain data packets.
ቢ Click 'Rules table'. This opens a window with a list of rules. Click 'Add'.
ባ You can define the rules in the window that follows. The following
options are available:
ć
'Source IP address': Source IP address, or 0.0.0.0 if the filter is to
apply to all IP addresses.
ć 'Source subnet mask': Source subnet mask which, together with the
source IP address, determines the source network, or 0.0.0.0 if the fil-
ter is to apply to all IP addresses.
ć 'From source port' and 'To source port' define the port range for the
packets being filtered. If both values are specified as 0, the filter
applies to all source ports.
