Abstract
In recent years, the number of users connected to the Internet has experienced a phenomenal growth. The security of systems and networks become essential. That is why the performance of Linux firewall and Berkeley Software Distribution (BSD) are of paramount importance in security systems and networks in all businesses. The following evaluates the firewall based tool that we have developed in Python and Scapy, which performs time measurements by serving packets traversing the firewall test. Several results were presented: the speed of the firewall under FreeBSD in terms of service time compared to the speed of the firewall under Linux as the number of rules increases; the speed of the filtering rule of a firewall stateless in terms of service time compared to the filtering rule of an active firewall gradually as the number of rules increases. Then, for care of simplicity, we have presented the queue M/M/1/K to model the performances of firewalls. The resulting model was validated using Simulink and mean squared error. The analytical model and Simulink of the firewalls are presented in the article.

We developed in python and Scapy 2.2.0 and its interface was made with Qt4 Designer
The Matlab tool was used for the activities of modeling, curves and comparison with firewalls and stateless firewalls; in particular depending on the number of rules using both TCP and UDP protocols
Summary
That is why firewalls such as IP cop Linux and BSD PF sense are of paramount importance. Various studies [1] [2] [3] proposed modeling, analysis, simulation and management of firewall policy; the work [4] [5] [6] presented designs, implementa-. L. Rabetafika tions firewall with software and hardware tools. [7]-[16] studied firewall filtering management and classifying packets in a secure architecture. In this paper there is a presentation tool which was developed in python and Scapy 2.2.0. Its interface was performed with Qt4 designer to measure the performance of the firewall. There is the presentation of the model in Simulink
