Site-to-Site VPN

Site-to-Site is a type of VPN configuration that connects two or more separate networks. In this setup, all devices in the connected networks can reach each other as if they were in a single local network. Site-to-Site VPNs are typically used to connect corporate locations, branch offices, or data centers. The configuration is usually performed on the network gateways or firewalls of the participating locations.
