A remote access VPN, or more specifically, a secure remote access VPN, is a virtual private network connection that offers remote workers, such as telecommuters or road warriors, a secure way into the network. This type of VPN is sometimes referred to as a “dial-up VPN” and allows single connections from multiple user access devices into a centralized VPN gateway.
Another class of VPN is a side-to-side virtual private network, typically used for secure connections between branch offices. Here, the secure tunneled connection is established between two or more gateway devices. There are two main VPN topologies for such a network. The first is a hub-and-spoke topology, where one gateway is the designated hub and the other gateways are the spokes, essentially, resembling a star topology. The second is mesh topology, where the gateways are interconnected. In a full mesh network, all gateways are connected directly to one another.
