Abstract: With the grown of internet, the transfer of package should be secured and grantee that availability, integrity, and confidentiality of data are met. Firewalls are multihomed server node models with gateway capabilities. The firewall rejects all remote-login traffic while accepting other applications. Based on the characteristics of their proxy servers, datagrams of some applications experience additional latency while being forwarded. This paper analyzed the use of firewall node model that connected as external network with different QoS parameters like: IP Traffic Dropped, Download Response Time, IP Processing Delay and Traffic Received. By applying the specified security policies, firewalls aim to protect the local network against the unauthorized access attempts from outside world.
