Open publisher page 0 citations

Abstract

IPSec protocols ensure data secure while it being transported across a network. NAT devices in a network change the data of a package header. There are problems when the VPN tunnel based on IPSec protocols passes through NAT devices. IPSec-NAT incompatibilities are discussed and implement of VPN's NAT traversal is introduced here. It has been implemented in VPN gateways, and solves the IPSec-NAT incompatibilities.
