VPN
Site to site VPN is used for connecting disparate sites to your LAN. See Remote access for information about remote user access. There are several ways to establish VPN connections between FortiProxys, and some that can be applied to other VPN appliances.
Site to site
Site to site VPNs are used for a single, secure connection between two sites, or between a site and a cloud service. The connection can be to an external party, such as a contractor or MSSP, or within the same business, such as to connect a remote site to the headquarters.
