Virtual Private Networks (VPN) are used create a private and secure connection to the public Internet.
VPN protects the privacy of the user by hiding the user’s location and identity when online.
A VPN gateway can be attached to a private network to establish a site-to-site VPN tunnel. With a VPN gateway, machines, devices, and third-party sites can communicate. To access the gateway, authentication and authorization is required. Strict rules are applied in order to protect the data transmitted as well maintaining a secure connection.
A site-to-site vpn is a networking setup where two or more networks are privately connected.
Site-to-site VPNs provide an encrypted link between VPN gateways located at each network and ensure encryption in data transfer until the data reaches its destination.
We restrict some DigitalOcean network traffic which prevents functionality like configuring direct server return and using Droplets as routers and site-to-site VPN gateways.
A VPN tunnel is a secret pipeline between two or more destinations in a protected private network over the Internet. It is dictated by rules and protocols on how data is shared within the network. Users can only have access to the tunnel if they have been authenticated.
