A site-to-site VPN allows campuses in multiple fixed locations to establish secure connections with each other over a public network such as the Internet. We established tunnels for interconnecting Ettimadai campus, Bengaluru campus and Kochi campus from Amritapuri campus over internet.
Even though the purpose of a site-to-site VPN is different from that of a remote-access VPN, it could use some of the same software and equipment. Ideally, though, a site-to-site VPN should eliminate the need for each computer to run VPN client software as if it were on a remote-access VPN. Site-to-site VPNs connect entire networks to each other, this means, site-to-site VPN can be used to connect a campus network to another remote campus network. Each site is equipped with a VPN gateway, such as a router, firewall or VPN concentrator
