Describe the two types of VPN networks.

Site-to-site VPNs:

  • A site-to-site VPN is an extension of classic WAN networking and can connect a branch office network to a company headquarters network.
  • Hosts send and receive TCP/IP traffic through a VPN “gateway,” which could be a router, PIX firewall appliance, or Adaptive Security Appliance (ASA).
  • The VPN gateway is responsible for encapsulating and encrypting outbound traffic for all the traffic from a particular site and sending it through a VPN tunnel over the Internet to a peer VPN gateway at the target site.
  • On receipt, the peer VPN gateway strips the headers, decrypts the content, and relays the packet toward the target host inside its private network.

Remote-access VPNs:

  • Mobile users and telecommuters use remote-access VPNs extensively.
  • Remote VPN connections typically take advantage of existing broadband connections.
  • Each host typically has VPN client software that encapsulates and encrypts that traffic before sending it over the Internet to the VPN gateway at the edge of the target network.
  • On receipt, the VPN gateway handles the data in the same way it would handle data from a site-to-site VPN.
