IP Filtering
Selecting Configuration>Network>IP Filtering in Expert mode brings up the
IP Filtering form as shown in the following figure.
Figure 4-34: IP Filtering Configuration Form
You can use the IP Filtering form to filter traffic to and from the KVM/net and
block traffic according to rules you define.
The KVM/net uses chains and rules for filtering packets like a firewall. Each
entry in the list represents a chain with a set of rules.
The form by default has three built-in chains, as shown in the previous figure.
The chains accept all INPUT, FORWARD, and OUTPUT packets. You can
use the form to do the following to specify packet filtering:
• Add a new chain and specify rules for that chain
• Add new rules
• Delete existing chains and rules.
Add Rule and Edit Rule Options
The Add Rule and Edit Rule dialog boxes have the fields and options shown
in the following figure.
