Abstract

Nowadays networking is not something new for us, we have hear about networking applications and problems every day at the present time. We can now easily communicate with each other despite the distance apart, exchange data, audio, video, and information. Network consists of Local Area Network (LAN) and Wide Area Network (WAN). Local Area Network is a computer network that covers only a small area networks, such as campus computer networks, buildings, offices, homes, or schools. While the Wide Area Network is a data communications network that operates beyond the geographic scope of the LAN. Knowing the applications, devices, and protocols before designing the network is very important to build a reliable and safe network. We have designed, build, and simulated a network using EIGRP, VPN, DMZ and IDS/IPS. The result of our simulation shows the network has a good performance, secure, and reliable.
