    Advanced Policy FirewallFree

    Advanced Policy Firewall (APF) is the best-in-class firewall based on iptables and features all the features and functionalities required by modern-day’s custom deployed Linux installations as well as Internet deployed servers. The configuration process is simple, easy to figure out, and is designed to provide every small and major information to the end-user so that they won’t have any trouble during usage. From a technical sense, the firewall makes use of up-to-date iptables (Netfilter) projects for better protection.

    There are three kinds of policies offered by APF are split into three policies named as Sanity based policies, Static rule-based policies, and Connection-based stateful policies. Each of these differs greatly from one another, and the goal behind this is to facilitate the end-user. The Static rule-based policy is basically the commonly known method of firewalling. This comes in handy when the firewall has a static set of instructions that determine how traffic should behave in specific conditions.

    A good example to clarify this scenario is when you refuse or allow an address to access the server using the trust system or utilizing conf.apf to open a new port. The Connection based stateful policy allows you to differentiate between legitimate packets for various connections. The features of Advanced Policy Firewall include optional rate-limited event logging, descriptive configuration file with comments for better understanding, debug mode, outbound network filtering based on user id, fast load feature, application-based network filtering, and optional implicit blocks of ident service. Apart from these, there are many more characteristics that have been added to deliver the best experience to the end-user.
