REMOTE ACCESS METHOD IN A NETWORK COMPRISING A NAT DEVICE

摘要

The present invention relates to a method for allowing remote access between an RAC (Remote Access Client) and an RAS (Remote Access Server) in a network environment employing a NAT (Network Address Translation) device, comprising acquiring a Transmission Address Set (TAS) for a Home Remote Access Server (Home RAS) from an external server, registering the acquired Transmission Address Set on a Transmission Address Resolution Server (TAR Server), receiving an IP packet from the remote access client using the registered transmission address set, and transmitting a response packet via the transmission path of the received IP packet. Thus, the RAC can remotely access the RAS even in the network comprising the NAT device and an optimum communication path can be resolved.
