Connect entire networks to each other, in the past, a leased line or Frame Relay connection was required to connect sites, but because most corporations now have Internet access, these connections can be replaced with site-to-site VPNs.

Internal hosts have no knowledge that a VPN exists.

Created when devices on both sides of the VPN connection are aware of the VPN configuration in advance.

End hosts send and receive normal TCP/IP traffic through a VPN gateway.

The VPN gateway is responsible for encapsulating and encrypting outbound traffic for all traffic from a particular site

The VPN gateway then sends it through a VPN tunnel over the Internet to a peer VPN gateway at the target site.

Upon receipt, the peer VPN gateway strips the headers, decrypts the content, and relays the packet toward the target host inside its private network.
