  • Shared port address translation on a router behaving as NAT & NAT-PT gateway
    Patent number: 7356045
    Abstract: A method for transparently sharing at least one IPv4 address among a plurality of hosts wherein at least a first host of the plurality of hosts uses the IPv4 protocol and wherein at least a second host of the plurality of hosts uses an IPv6 protocol is provided. A first data having a first source address and a first destination address is received. A network address translation with port address translation is performed, if the first data is in an IPv4 protocol. A network address translation protocol translation with port address translation is performed, if the first data is in an IPv6 protocol.
    Type: Grant

  • Method and apparatus for providing IPv6 networks to communicate with overlapping IPv4 networks using NAT-PT
    Patent number: 7333510
    Abstract: A method for providing handling of data sent between a first network and at least a second network and a third network, wherein the first network is of a first protocol and the at least second and third networks are of a second protocol at least partially overlap is provided. A packet transmitted from the first network is received. The packet has a first address prefix if the packet is directed to the second network and has a second address prefix if the packet is directed to the third network. A destination address of the packet and a source address of the packet are translated from the first protocol to the second protocol. The packet is directed to the second network if the packet has the first address prefix. The packet is directed to the third network if the packet has the second address prefix.
