Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
From the end user, packets travel over a wholesale network service provider's network to a server called a Broadband Remote Access Server , a protocol converter and router combined. On legacy networks the path from end user customer premises' equipment to the BRAS may be over an ATM network. From there on, over an IP network, an L2TP tunnel ...
As such, it may not be a viable authentication option for some remote access installations. Most networks that use PPTP have to apply additional security measures or be deemed completely inappropriate for the modern internet environment. At the same time, doing so means negating the aforementioned benefits of the protocol to some point. [12]
It is then encapsulated into a new IP packet with a new IP header. Tunnel mode is used to create virtual private networks for network-to-network communications (e.g. between routers to link sites), host-to-network communications (e.g. remote user access) and host-to-host communications (e.g. private chat). [32] Tunnel mode supports NAT traversal.
OpenVPN Access Server (OpenVPN-AS) is based on the Community Edition, but provides additional paid and proprietary features like LDAP integration, SMB server, Web UI management and provides a set of installation and configuration tools that are reported to simplify the rapid deployment of a VPN remote-access solution.
For example, suppose a user utilizes a remote access VPN software client connecting to a campus network using a hotel wireless network. The user with split tunneling enabled is able to connect to file servers , database servers , mail servers and other servers on the corporate network through the VPN connection.
