IPv6 deployments use different NGtrans mechanisms, depending on the network situation. Therefore, a mobile network should be able to initiate secure connectivity with the corresponding home network. The correlation between transition mechanisms used in existing network and transition mechanisms supported by the mobile network, is an important factor in secure connectivity with a corresponding home network. In this paper, VPN scenarios applicable to mobile networks during the transition to IPv6, have been analyzed. In addition, performance costs have also been evaluated, in order to establish connectivity according to VPN models with each transition phase. In addition, this paper analyzes factors affecting performance, through numeric analysis for NEMO VPN model, under an IPv6 transition environment. As shown in our study, a NEMO VPN creating hierarchical or sequential tunnels should be proposed after careful evaluation of not only security vulnerabilities but also performance requirements.
