FreeBSD Firewall

If man cannot live alone, the same thing goes for computers. Even if a personal computer is not part of a LAN (Local Area Network), somehow it still is connected to the main stream – the Internet. With millions of websites in the world, no wonder that web developers and administrators are always on the lookout for reliable and even free open source firewalls to protect their most valuable servers. One of the important tasks they need to know and implement is how to configure a FreeBSD Firewall.

FreeBSD – recently being regarded as the “Uknown giant among free operating systems” is gaining its name as an advanced and robust operating system for servers, desktops and other computer platforms. For over thirty years, a large group of individuals are behind its creation, maintenance and constant improvement. Most of the information congested websites are run by powerful servers that are protected by a FreeBSD firewall, together with it, are its remarkable security capabilities and its ability to handle complex network activities.

On the other hand, one open source software for servers such as Linux has one of its distributions also known as the famous Ubuntu. An Ubuntu firewall can still be configured to run together with a FreeBSD firewall . This combination produces a very stable and secure network. Both of these firewall uses sets of rules to check network packets that flow through the network. It acts like a police that allows or blocks certain connections as customized by the administrator. Moreover, there are three different firewall packages built into a FreeBSD configuration, one is the IPFILTER (IPF), IPFIREWALL (IPFW) and OPENBSD’a  Packetfilter (PF). By default, there are different three FreeBSD firewall because different people have different needs. To learn more about the deeper configuration for this set-up, various information are readily available in the internet. Look for resources under Ubuntu, FreeBSD.org online, and Ubuntu firewall search keys.

To conclude, since FreeBSD and Ubuntu are both open source applications meaning and there are lots of developers all working together for its constant improvement hence firewalls built on this systems is enough to assure the most doubtful of minds.
