Fact Sheet on Linux Firewall Builder

Firewall Builder is a firewall management and graphical configuration tool that supports many open source platforms, Cisco IOS firewall. Firewall Builder is mostly used Linux operating systems. This tutorial shows you how to use objects in the object interface firewall interface Builder.Interface objects are used by firewalls to accommodate objects and can not exist alone. The dialog box specific to the interface object that belongs to the firewall can be described in several parameters. Here is a list of these categories: Name – The name of the object of the interface must match the name of the interface of the firewall machine represents.Management – If a firewall has multiple network interfaces, one of them must be assigned to management "interface", which is used for all communication between Firewall Builder and specific firewall.Label – This field is not used, but it serves the purpose of an interface description label.Unprotected: an interface that is not to assign any access lists or firewall rules. External Interface: Assign an interface that connects directly to the interface Internet.Regular – This option is used when the interface has an IP address assigned to it.Address dynamically allocated – Unlike the normal interface, this option is used when the interface has a dynamic Puerto address.Bridge – Use this option for a bridge port interface firewall.Unnumbered – Use this option if the interface and you can not have an IP address.Security level – This option is self-explanatory it. The security level can be set to external, internal, or have a numeric value between 0 and Zone 100.Network – This option is used to establish the zone Cisco PIX network. The dropdown list shows all current network objects. The user will then have the option of choosing one of these network objects to the order of the compiler that refers to the network can be reached.Assigning Use Policy Rules ObjectYou interface can use the object interface to assign the rules of policy. For example, you can drag and drop or copy and objects beyond the interface to the policy column for the firewall rules match. You can also use the interface object with dynamic addresses in the rules of politics. When an interface has a dynamically assigned address, this means that the address is unknown to the compiler Firewall Builder policy when the configuration script is generated. The compiler uses the features of the firewall order to solve this problem.
