Information and communication system technology with VPN site-to-site IPsec

This research aims to solve network problems in Information and Communication Technology (ICT) project at Gelora Bung Karno (GBK) gym building. The ICT project was created for the 18th Asian Games event. The technologies used in ICT projects in GBK are VLAN (virtual lan) and Virtual Private Network (VPN). The problem in this ICT project is the end device must be connected through the two switched layers but using a different network. VLAN is a solution to divide the network segment without having to follow the physical condition of the device. This project was made by using four stages. Those stages are analysis, design, implementation and testing. On ICT systems, VLAN are used to divide network segments required for Access Point and CCTV requirements. VLAN are simulated in GNS3 and VMWARE software. As a result, access points and CCTV as end users are connected to the core routers in the network operational center via the layer two switch. The next problem is the lack of efficient monitoring and troubleshooting system. Monitoring and troubleshooting systems must be done from the Network Operational Center (NOC) in GBK. Monitoring and troubleshooting systems are more effectively done directly from the developer's local network by accessing the local network of ICT projects over the internet. This mechanism is called a VPN. VPN technology is used to access local networks that exist in ICT projects using the local network of related developer companies. The VPN uses IPSec as encryption for the packet data equality. The results show that VPN is able to connect local network in ICT GBK project with local network of developer company through internet.
