Abstract：NAT64isatechnologythatconvertsIPv6packetsinto IPv4packets.Withthepromotionof IPv6，the interconnection between IPv4 and IPv6 networks has become a key issue.As a core technology for realizing heterogeneous networkcommunication，NAT64playsanimportantroleinnetworktransition.BasedontheHuaweiUSG60OOvfirewallthispaper constructsahybridnetworkenvironmentincludingwiredandwirelessscenariosthroughtheeNSPsimulationpltfomtostudythe principles，configurationmethods，andsecuritypoliciesofNAT64technology.Bysimulatingbidirectionalcommunicationbetween IPv6andIPv4networks，thefeasibityand'securityofNAT64inhybridnetworkenvironmentsareverfied.Combinedwith performancetestdata，itsimpactonthenetworkisquantiativelyanalyzedtoprovideatechnicalreferenceforthesmoth transitionofenterprisenetworks.TheresultsshowthattheNAT64configurationoftheHuaweiUSG6OOvfrewallcanffectively achieveheterogeneousnetworkinterconnection.Whileensuringnetworksecurity，itsperformancemetstheactualdeployment requirements of enterprises，providingareliableand eficient technical reference for IPv4/IPv6 transition.
