METHOD AND DEVICE FOR SUPPORTING A 6TO4 TUNNELING PROTOCOL ACROSS A NETWORK ADDRESS TRANSLATION MECHANISM

摘要

Through a network address translation mechanism is disclosed a method for supporting a 6to4 tunneling protocol. The method includes receiving a transmission side IPv6 packet encapsulated into an IPv4 packet, and converts the private IPv4 source address in the IPv4 header of the outbound packet into a public IPv4 source address, and transmits the converted packet over the IPv4 network and, to the step of the bonding of the interface ID value of the private IPv4 address and the 6to4 source address for opposite address translation stored in the inbound packet further comprising. The corresponding apparatus is also claimed. ; 6to4 tunneling, IPv4 packets, IPv6 packets, private address, public address, encapsulation
