VPN server that connects telework users with VPN

　Interlink's "Group -only VPN Server+NGN" is a VPN service that allows multiple members working in a telework environment to share the same network (group LAN).

　As a component of the system, a VPN server connected to both NGN and the Internet on the NTT FLET'S line is provided.The user connects to the VPN server from the terminal where the VPN client software is installed via the Internet connection line.

　It is a service that specializes in using a VPN client on a PC to share a VPN segment.Members connected to the VPN server can belong to the same network like in -house LAN.

　On the VPN server, the open source WireGuard is operating as a VPN software.It is a VPN function built into the Linux kernel, and can be used by installing VPN client software on Windows or Mac.

　Both NTT FLET'S line NGN and Internet can be used as a connecting route to the VPN server.The NGN network can use the NTT East NGN network at the beginning of the service.The NTT West NGN network will be available within 2021.

　Users who use NGN on the Internet connection line can directly connect to the VPN server without going through the provider (Internet connection operator) network.Users who do not use NGN connect via the Internet (the VPN server to be connected has a fixed IPV4 fixed IP address).

　If you need higher security, you can prohibit access from the Internet (IPv4) by setting the control panel.In this case, it can only be accessed from the NGN network.If the server to be accessed is installed in NGN, it will be less likely to receive unauthorized access.
