Firewall and NAT
The firewall and NATfeature enables an administrator to configure the rules governing traffic
filtering, IPforwarding and address translation within the appliance.
NOTE: The appliance is specially designed for managing and providing access to device management
consoles. It is not supported as a general purpose router, switch or packet filter.
The firewall and NAT features are built from a series of named definitions for networks, hosts,
interfaces and services. Before you can configure the firewall and NAT policies, you must define
the objects that will be used within the policy rules. It is best to start by defining the interfaces, then
defining the networks that will be referenced by your policy rules before finally defining the hosts
and services. Each of these are described in the next sections.
The appliance will already have knowledge of various hosts, networks and interfaces; these objects
will be created at the time they are defined or discovered by the appliance. For example, upon
connecting a UMIQmodule to the appliance, a host definition will be created matching the name
assigned to the UMIQ module target.
Interfaces
By default, all physical and virtual interfaces defined within the appliance will be listed on the
Interfaces tab. You can access the Interfaces tab by clicking Firewall and NAT from the sidebar.
