5 Configuring Firewall/NAT Settings

5.1

DoS (Denial of Service) Protection and Stateful Packet Inspection

5.2

Default ACL Rules

SL-6000 provides built-in firewall/NAT functions, enabling you to
protect the system against denial of service (DoS) attacks and other
types of malicious accesses to your LAN while providing Internet
access sharing at the same time. You can also specify how to
monitor attempted attacks, and who should be automatically
notified.
This chapter describes how to create/modify/delete ACL (Access
Control List) rules to control the data passing through your network.
You will use firewall configuration pages to:
Create, modify and delete inbound/outbound ACL rules.
Create, modify and delete pre-defined services to be used
in inbound/outbound ACL configurations.
View ACL inbound/outbound rules
View firewall statistics.
Note: •When you define an ACL rule, you instruct the SL-6000 to
examine each data packet it receives to determine whether it meets
criteria set forth in the rule. The criteria can include the network or
internet protocol it is carrying, the direction in which it is traveling (for
example, from the LAN to the Internet or vice versa), the IP address
of the sending computer, the destination IP address, and other
characteristics of the packet data. If the packet matches the criteria
established in a rule, the packet can either be accepted (forwarded
towards its destination), or denied (discarded), depending on the
action specified in the rule.
The firewall as implemented in SL-6000 provides DoS protection
and stateful packet inspection as the first line security for your
network. No configuration is required for this protection on your
network as long as firewall is enabled for SL-6000. By default, the
firewall is enabled at the factory.
SL-6000 supports three types of default access rules:
Inbound Access Rules: for controlling incoming access to
computers on your LAN.
Outbound Access Rules: for controlling outbound access to
external networks for hosts on your LAN.
Self Access Rules: for controlling access to SL-6000 itself.
