Firewall Configuration
Firewall configuration, also known as IP filtering, refers to the selective blocking of the passage
of IP packets between global and local networks. The filtering is based on rules that describe
the characteristics of the packet. For example, the contents of the IP header, the input/output
interface or the protocol.
This feature is used mainly in firewall applications to filter the packets that could potentially
harm the network system or generate unnecessary traffic in the network.
You can use the Firewall Configuration form to enable a firewall on the console server. You
can define rules to allow or disallow packets and configure filtering of packets that are sent and
received through the console server.
The administrator can configure the device to filter packets like a firewall. Packet filtering relies
on defined chains and rules.
Each entry in the list on the Firewall Configuration form represents a chain with a set of rules.
By default the list has three built-in chains. The chains accept all INPUT, FORWARD and
OUTPUT packets. You can use the Edit, Delete, Add and Edit Rules buttons on the form to
perform the following to configure packet filtering:
