If Flag is checked the event is flagged for easier viewing in the event log.įlag is always enabled if the action is Block. It is up to you to decide to best fit for your network, whether you only want to block specific ports or you want to block everything and allow only a few services.Īdditionally a session can be flagged. In this scenario all inbound sessions are blocked by NAT except those explicitly allowed with port forwards.īecause of this, the Firewall does not block anything by default. Flagging a session marks it in the logs for reviewing in the event logs or reports, but has no direct effect on the network traffic. The Rules documentation describes how rules work and how they are configured. The Firewall app provides the same functionality as the traditional "firewall" - the ability to use rules to control which computers and communicate on a network.
Good reporting visible via a Web interface, and with alerts sent via email is very important.The term "Firewall" has grown to encompass many functionalities and has a wide array of meanings. The firewall acts as a VPN endpoint and the rules component helps manage what remote VPN users or sites can and cannot access on the network. Almost all current firewalls provide virtual private network VPN functions. Firewalls go far beyond this basic functionality, however. These are required components for any system calling itself a firewall. An interface for creating and managing these rules, usually a Web interface for ease-of-use is also needed. TCP and UDP protocol management beyond basic port filtering is important as well, allowing or restricting particular applications or functions. The firewall components and applications you require include a core routing and protocol filtering component, which also can provide network address translation NAT functionality.

Some free firewall packages include the base Linux OS and install completely, without the need for selecting, downloading and installing or compiling individual components, configuring Web management or other controls, and so forth.

Windows is a possibility, but most all of the Open Source firewall applications were designed to run on Linux or other Unix variants in some cases. First you will need to choose an operating system platform for your firewall. Network design, firewall rules creation and testing, and firewall deployment are all discussed.

This article examines what hardware and software components you need, firewall design basics, and how to configure, test, and deploy a strong firewall. Home users might consider a Wi-Fi adapter for the internal interface since they may not have or want cabling connecting the firewall to the ideal spot for their wireless router or hub.īuild Your Own Firewall: Software ComponentsCreating a firewall using your own hardware and free firewall software and applications is possible. You may want to use a gigabit BaseT Ethernet interface for your internal networks if you want or need the higher throughput. One for your internal or protected network, and another for the external or Internet network. The main point here is that you will want one network interface for each physical network: two at a minimum. This can either be a good thing or a bad thing. Next you should consider network interface NIC options. First, you will want to be sure that the motherboard has a high-performance bus controller and that there are enough expansion slots to accomplish what you want. Engineering and deploying firewalls created from scratch will take more time and effort than installing a commercial product, but the result can be optimized and tuned for your particular technical needs.
