There are many standards and protocols for VPNs The standard implemented in the LevelOne Broadband VPN Gateway is IPSec IPSec IPSec is a near ubiquitous VPN security standard designed for use with TCP IP networks It works at the packet level and authenticates and encrypts all packets traveling over the VPN Tunnel Thus it does not matter what applications are used on your PC Any application can use the VPN like any other network connection IPsec VPNs exchange information through logical connections called SAs Security Associa tions An SA is simply a definition of the protocols algorithms and keys used between the two VPN devices endpoints Each IPsec VPN has two SAs one in each direction If IKE Internet Key Exchange is used to generate and exchange keys there are also SA s for the IKE connection as well as the IPsec connection There are two security modes possible with IPSec e Transport Mode the payload data part of the packet 1s encapsulated through encryp tion but the IP header remains in the clear unchanged The LevelOne Broadband VPN Gateway does NOT support Transport Mode e Tunnel Mode everything is encapsulated including the original IP header and a new IP header is generated Only the new header in the clear 1 e not protected This system pro vides enhanced security The LevelOne Broadband VPN Gateway always uses Tunnel Mode IKE IKE Internet Key Exchange is an optional but widel
