Abstract
A communication method and apparatus using the IP address of a gateway for an MN in a VPN are provided. When the MN is to access the VPN, the gateway acting an FA in the VPN performs a Mobile IP registration on behalf of the MN and is allocated a HoA for the MN from an HA. Therefore, the number of addresses required for the Mobile IP registration of the MN is reduced and overlap between an IP-in-IP tunnel for Mobile Internet and an IPsec tunnel for the VPN is avoided. As a result, packet transmission overhead is reduced.
