Paper Abstract

Similar to conventional NAT gateways, NAT-PT gateways break traditional TCP/IP’s end-to-end argument property; hence, any IP-based applications protected by IPSec protocol cannot traverse NAT-PT gateways properly. The interworking issues between IPSec and NAT-PT gateways under IPv4/IPv6 co-existent environments were studied: this paper first pointed out the deficiency of current NAT-Traversal scheme when interworking with NAT-PT gateways and proposed an enhanced scheme, which enabled interworking between IPSec and NAT-PT gateways and served the following three scenarios: 1) secure communication between IPv6 hosts and IPv4 hosts; 2) secure communication between IPv6 subnets and IPv4 subnets; 3) secure communication between remote IPv6 hosts and legacy IPv4 subnets.
